Justice White
delivered the opinion of the Court.
At issue in this case is the constitutionality of a New York criminal statute which prohibits persons from knowingly promoting sexual performances by children under the age of 16 by distributing material which depicts such performances.
I
In recent years, the exploitive use of children in the production of pornography has become a serious national problem. The Federal Government and 47 States have sought to combat the problem with statutes specifically directed at the production of child pornography. At least half of such statutes do not require that the materials produced be legally obscene. Thirty-five States and the United States Congress have also passed legislation prohibiting the distribution of such materials; 20 States prohibit the distribution of material depicting children engaged in sexual conduct without requiring that the material be legally obscene.
New York is one of the 20. In 1977, the New York Legislature enacted Article 263 of its Penal Law. N. Y. Penal Law, Art. 263 (McKinney 1980). Section 263.05 criminalizes as a class C felony the use of a child in a sexual performance:
“A person is guilty of the use of a child in a sexual performance if knowing the character and content thereof he employs, authorizes or induces a child less than sixteen years of age to engage in a sexual performance or being a parent, legal guardian or custodian of such child, he consents to the participation by such child in a sexual performance.”
A “[s]exual performance” is defined as “any performance or part thereof which includes sexual conduct by a child less than sixteen years of age.” § 263.00(1). “Sexual conduct” is in turn defined in §263.00(3):
“ ‘Sexual conduct’ means actual or simulated sexual intercourse, deviate sexual intercourse, sexual bestiality, masturbation, sado-masochistic abuse, or lewd exhibition of the genitals.”
A performance is defined as “any play, motion picture, photograph or dance” or “any other visual representation exhibited before an audience.” §263.00(4).
At issue in this case is §263.15, defining a class D felony:
“A person is guilty of promoting a sexual performance by a child when, knowing the character and content thereof, he produces, directs or promotes any performance which includes sexual conduct by a child less than sixteen years of age.”
To “promote” is also defined:
“‘Promote’ means to procure, manufacture, issue, sell, give, provide, lend, mail, deliver, transfer, transmute, publish, distribute, circulate, disseminate, present, exhibit or advertise, or to offer or agree to do the same.” §263.00(5).
A companion provision bans only the knowing dissemination of obscene material. §263.10.
This case arose when Paul Ferber, the proprietor of a Manhattan bookstore specializing in sexually oriented products, sold two films to an undercover police officer. The films are devoted almost exclusively to depicting young boys masturbating. Ferber was indicted on two counts of violating §263.10 and two counts of violating §263.15, the two New York laws controlling dissemination of child pornography. After a jury trial, Ferber was acquitted of the two counts of promoting an obscene sexual performance, but found guilty of the two counts under §263.15, which did not require proof that the films were obscene. Ferber’s convictions were affirmed without opinion by the Appellate Division of the New York State Supreme Court. 74 App. Div. 2d 558, 424 N. Y. S. 2d 967 (1980).
The New York Court of Appeals reversed, holding that §263.15 violated the First Amendment. 52 N. Y. 2d 674, 422 N. E. 2d 523 (1981). The court began by noting that in light of § 263.10’s explicit inclusion of an obscenity standard, §263.15 could not be construed to include such a standard. Therefore, “the statute would . . . prohibit the promotion of materials which are traditionally entitled to constitutional protection from government interference under the First Amendment.” 52 N. Y. 2d, at 678, 422 N. E. 2d, at 525. Although the court recognized the State’s “legitimate interest in protecting the welfare of minors” and noted that this “interest may transcend First Amendment concerns,” id., at 679, 422 N. E. 2d, at 525-526, it nevertheless found two fatal defects in the New York statute. Section 263.15 was under-inclusive because it discriminated against visual portrayals of children engaged in sexual activity by not also prohibiting the distribution of films of other dangerous activity. It was also overbroad because it prohibited the distribution of materials produced outside the State, as well as materials, such as medical books and educational sources, which “deal with adolescent sex in a realistic but nonobscene manner.” 52 N. Y. 2d, at 681, 422 N. E. 2d, at 526. Two judges dissented. We granted the State’s petition for certiorari, 454 U. S. 1052 (1981), presenting the single question:
“To prevent the abuse of children who are made to engage in sexual conduct for commercial purposes, could the New York State Legislature, consistent with the First Amendment, prohibit the dissemination of material which shows children engaged in sexual conduct, regardless of whether such material is obscene?”
II
The Court of Appeals proceeded on the assumption that the standard of obscenity incorporated in §263.10, which follows the guidelines enunciated in Miller v. California, 413 U. S. 15 (1973), constitutes the appropriate line dividing protected from unprotected expression by which to measure a regulation directed at child pornography. It was on the premise that “nonobscene adolescent sex” could not be singled out for special treatment that the court found §263.15 “strikingly underinclusive.” Moreover, the assumption that the constitutionally permissible regulation of pornography could not be more extensive with respect to the distribution of material depicting children may also have led the court to conclude that a narrowing construction of §263.15 was unavailable.
The Court of Appeals’ assumption was not unreasonable in light of our decisions. This case, however, constitutes our first examination of a statute directed at and limited to depictions of sexual activity involving children. We believe our inquiry should begin with the question of whether a State has somewhat more freedom in proscribing works which portray sexual acts or lewd exhibitions of genitalia by children.
A
In Chaplinsky v. New Hampshire, 315 U. S. 568 (1942), the Court laid the foundation for the excision of obscenity from the realm of constitutionally protected expression:
“There are certain well-defined and narrowly limited classes of speech, the prevention and punishment of which have never been thought to raise any Constitutional problem. These include the lewd and obscene .... It has been well observed that such utterances are no essential part of any exposition of ideas, and are of such slight social value as a step to truth that any benefit that may be derived from them is clearly outweighed by the social interest in order and morality.” Id., at 571-572 (footnotes omitted).
Embracing this judgment, the Court squarely held in Roth v. United States, 354 U. S. 476 (1957), that “obscenity is not within the area of constitutionally protected speech or press.” Id., at 485. The Court recognized that “rejection of obscenity as utterly without redeeming social importance” was implicit in the history of the First Amendment: The original States provided for the prosecution of libel, blasphemy, and profanity, and the “universal judgment that obscenity should be restrained [is] reflected in the international agreement of over 50 nations, in the obscenity laws of all of the 48 states, and in the 20 obscenity laws enacted by Congress from 1842 to 1956.” Id., at 484-485 (footnotes omitted).
Roth was followed by 15 years during which this Court struggled with “the intractable obscenity problem.” Interstate Circuit, Inc. v. Dallas, 390 U. S. 676, 704 (1968) (opinion of Harlan, J.). See, e. g., Redrup v. New York, 386 U. S. 767 (1967). Despite considerable vacillation over the proper definition of obscenity, a majority of the Members of the Court remained firm in the position that “the States have a legitimate interest in prohibiting dissemination or exhibition of obscene material when the mode of dissemination carries with it a significant danger of offending the sensibilities of unwilling recipients or of exposure to juveniles.” Miller v. California, supra, at 18-19 (footnote omitted); Stanley v. Georgia, 394 U. S. 557, 567 (1969); Ginsberg v. New York, 390 U. S. 629, 637-643 (1968); Interstate Circuit, Inc. v. Dallas, supra, at 690; Redrup v. New York, supra, at 769; Jacobellis v. Ohio, 378 U. S. 184, 195 (1964).
Throughout this period, we recognized “the inherent dangers of undertaking to regulate any form of expression.” Miller v. California, supra, at 23. Consequently, our difficulty was not only to assure that statutes designed to regulate obscene materials sufficiently defined what was prohibited, but also to devise substantive limits on what fell within the permissible scope of regulation. In Miller v. California, supra, a majority of the Court agreed that a “state offense must also be limited to works which, taken as a whole, appeal to the prurient interest in sex, which portray sexual conduct in a patently offensive way, and which, taken as a whole, do not have serious literary, artistic, political, or scientific value.” Id., at 24. Over the past decade, we have adhered to the guidelines expressed in Miller, which subsequently has been followed in the regulatory schemes of most States.
B
The Miller standard, like its predecessors, was an accommodation between the State’s interests in protecting the “sensibilities of unwilling recipients” from exposure to pornographic material and the dangers of censorship inherent in unabashedly content-based laws. Like obscenity statutes, laws directed at the dissemination of child pornography run the risk of suppressing protected expression by allowing the hand of the censor to become unduly heavy. For the following reasons, however, we are persuaded that the States are entitled to greater leeway in the regulation of pornographic depictions of children.
First. It is evident beyond the need for elaboration that a State’s interest in “safeguarding the physical and psychological well-being of a minor” is “compelling.” Globe Newspaper Co. v. Superior Court, 457 U. S. 596, 607 (1982). “A democratic society rests, for its continuance, upon the healthy, well-rounded growth of young people into full maturity as citizens.” Prince v. Massachusetts, 321 U. S. 158, 168 (1944). Accordingly, we have sustained legislation aimed at protecting the physical and emotional well-being of youth even when the laws have operated in the sensitive area of constitutionally protected rights. In Prince v. Massachusetts, supra, the Court held that a statute prohibiting use of a child to distribute literature on the street was valid notwithstanding the statute’s effect on a First Amendment activity. In Ginsberg v. New York, supra, we sustained a New York law protecting children from exposure to nonobscene literature. Most recently, we held that the Government’s interest in the “well-being of its youth” justified special treatment of indecent broadcasting received by adults as well as children. FCC v. Pacifica Foundation, 438 U. S. 726 (1978).
The prevention of sexual exploitation and abuse of children constitutes a government objective of surpassing importance. The legislative findings accompanying passage of the New York laws reflect this concern:
“[T]here has been a proliferation of exploitation of children as subjects in sexual performances. The care of children is a sacred trust and should not be abused by those who seek to profit through a commercial network based upon the exploitation of children. The public policy of the state demands the protection of children from exploitation through sexual performances.” 1977 N. Y. Laws, ch. 910, § l.
We shall not second-guess this legislative judgment. Respondent has not intimated that we do so. Suffice it to say that virtually all of the States and the United States have passed legislation proscribing the production of or otherwise combating “child pornography.” The legislative judgment, as well as the judgment found in the relevant literature, is that the use of children as subjects of pornographic materials is harmful to the physiological, emotional, and mental health of the child. That judgment, we think, easily passes muster under the First Amendment.
Second. The distribution of photographs and films depicting sexual activity by juveniles is intrinsically related to the sexual abuse of children in at least two ways. First, the materials produced are a permanent record of the children’s participation and the harm to the child is exacerbated by their circulation. Second, the distribution network for child pornography must be closed if the production of material which requires the sexual exploitation of children is to be effectively controlled. Indeed, there is no serious contention that the legislature was unjustified in believing that it is difficult, if not impossible, to halt the exploitation of children by pursuing only those who produce the photographs and movies. While the production of pornographic materials is a low-profile, clandestine industry, the need to market the resulting products requires a visible apparatus of distribution. The most expeditious if not the only practical method of law enforcement may be to dry up the market for this material by imposing severe criminal penalties on persons selling, advertising, or otherwise promoting the product. Thirty-five States and Congress have concluded that restraints on the distribution of pornographic materials are required in order to effectively combat the problem, and there is a body of literature and testimony to support these legislative conclusions. Cf. United States v. Darby, 312 U. S. 100 (1941) (upholding federal restrictions on sale of goods manufactured in violation of Fair Labor Standards Act).
Respondent does not contend that the State is unjustified in pursuing those who distribute child pornography. Rather, he argues that it is enough for the State to prohibit the distribution of materials that are legally obscene under the Miller test. While some States may find that this approach properly accommodates its interests, it does not follow that the First Amendment prohibits a State from going further. The Miller standard, like all general definitions of what may be banned as obscene, does not reflect the State’s particular and more compelling interest in prosecuting those who promote the sexual exploitation of children. Thus, the question under the Miller test of whether a work, taken as a whole, appeals to the prurient interest of the average person bears no connection to the issue of whether a child has been physically or psychologically harmed in the production of the work. Similarly, a sexually explicit depiction need not be “patently offensive” in order to have required the sexual exploitation of a child for its production. In addition, a work which, taken on the whole, contains serious literary, artistic, political, or scientific value may nevertheless embody the hardest core of child pornography. “It is irrelevant to the child [who has been abused] whether or not the material. . . has a literary, artistic, political or social value.” Memorandum of Assemblyman Lasher in Support of §263.15. We therefore cannot conclude that the Miller standard is a satisfactory solution to the child pornography problem.
Third. The advertising and selling of child pornography provide an economic motive for and are thus an integral part of the production of such materials, an activity illegal throughout the Nation. “It rarely has been suggested that the constitutional freedom for speech and press extends its immunity to speech or writing used as an integral part of conduct in violation of a valid criminal statute.” Giboney v. Empire Storage & Ice Co., 336 U. S. 490, 498 (1949). We note that were the statutes outlawing the employment of children in these films and photographs fully effective, and the constitutionality of these laws has not been questioned, the First Amendment implications would be no greater than that presented by laws against distribution: enforceable production laws would leave no child pornography to be marketed.
Fourth. The value of permitting live performances and photographic reproductions of children engaged in lewd sexual conduct is exceedingly modest, if not de minimis. We consider it unlikely that visual depictions of children performing sexual acts or lewdly exhibiting their genitals would often constitute an important and necessary part of a literary performance or scientific or educational work. As a state judge in this case observed, if it were necessary for literary or artistic value, a person over the statutory age who perhaps looked younger could be utilized. Simulation outside of the prohibition of the statute could provide another alternative. Nor is there any question here of censoring a particular literary theme or portrayal of sexual activity. The First Amendment interest is limited to that of rendering the portrayal somewhat more “realistic” by utilizing or photographing children.
Fifth. Recognizing and classifying child pornography as a category of material outside the protection of the First Amendment is not incompatible with our earlier decisions. “The question whether speech is, or is not, protected by the First Amendment often depends on the content of the speech.” Young v. American Mini Theatres, Inc., 427 U. S. 50, 66 (1976) (opinion of Stevens, J., joined by Burger, C. J., and White and Rehnquist, JJ.). See also FCC v. Pacifica Foundation, 438 U. S. 726, 742-748 (1978) (opinion of Stevens, J., joined by Burger, C. J., and Rehnquist, J.). “[I]t is the content of [an] utterance that determines whether it is a protected epithet or an unprotected ‘fighting comment.’” Young v. American Mini Theatres, Inc., supra, at 66. See Chaplinsky v. New Hampshire, 315 U. S. 568 (1942). Leaving aside the special considerations when public officials are the target, New York Times Co. v. Sullivan, 376 U. S. 254 (1964), a libelous publication is not protected by the Constitution. Beauhamais v. Illinois, 343 U. S. 250 (1952). Thus, it is not rare that a content-based classification of speech has been accepted because it may be appropriately generalized that within the confines of the given classification, the evil to be restricted so overwhelmingly outweighs the expressive interests, if any, at stake, that no process of case-by-case adjudication is required. When a definable class of material, such as that covered by § 26B. 15, bears so heavily and pervasively on the welfare of children engaged in its production, we think the balance of competing interests is clearly struck and that it is permissible to consider these materials as without the protection of the First Amendment.
C
There are, of course, limits on the category of child pornography which, like obscenity, is unprotected by the First Amendment. As with all legislation in this sensitive area, the conduct to be prohibited must be adequately defined by the applicable state law, as written or authoritatively construed. Here the nature of the harm to be combated requires that the state offense be limited to works that visually depict sexual conduct by children below a specified age. The category of “sexual conduct” proscribed must also be suitably limited and described.
The test for child pornography is separate from the obscenity standard enunciated in Miller, but may be compared to it for the purpose of clarity. The Miller formulation is adjusted in the following respects: A trier of fact need not find that the material appeals to the prurient interest of the average person; it is not required that sexual conduct portrayed be done so in a patently offensive manner; and the material at issue need not be considered as a whole. We note that the distribution of descriptions or other depictions of sexual conduct, not otherwise obscene, which do not involve live performance or photographic or other visual reproduction of live performances, retains First Amendment protection. As with obscenity laws, criminal responsibility may not be imposed without some element of scienter on the part of the defendant. Smith v. California, 361 U. S. 147 (1959); Hamling v. United States, 418 U. S. 87 (1974).
D
Section 263.15’s prohibition incorporates a definition of sexual conduct that comports with the above-stated principles. The forbidden acts to be depicted are listed with sufficient precision and represent the kind of conduct that, if it were the theme of a work, could render it legally obscene: “actual or simulated sexual intercourse, deviate sexual intercourse, sexual bestiality, masturbation, sado-masochistic abuse, or lewd exhibition of the genitals.” § 263.00(3). The term “lewd exhibition of the genitals” is not unknown in this area and, indeed, was given in Miller as an example of a permissible regulation. 413 U. S., at 25. A performance is defined only to include live or visual depictions: “any play, motion picture, photograph or dance . . . [or] other visual representation exhibited before an audience.” §263.00(4). Section 263.15 expressly includes a scienter requirement.
We hold that §263.15 sufficiently describes a category of material the production and distribution of which is not entitled to First Amendment protection. It is therefore clear that there is nothing unconstitutionally “underinclusive” about a statute that singles out this category of material for proscription. It also follows that the State is not barred by the First Amendment from prohibiting the distribution of unprotected materials produced outside the State.
Ill
It remains to address the claim that the New York statute is unconstitutionally overbroad because it would forbid the distribution of material with serious literary, scientific, or educational value or material which does not threaten the harms sought to be combated by the State. Respondent prevailed on that ground below, and it is to that issue that we now turn.
The New York Court of Appeals recognized that over-breadth scrutiny has been limited with respect to conduct-related regulation, Broadrick v. Oklahoma, 413 U. S. 601 (1973), but it did not apply the test enunciated in Broadrick because the challenged statute, in its view, was directed at “pure speech.” The court went on to find that §263.15 was fatally overbroad: “[T]he statute would prohibit the showing of any play or movie in which a child portrays a defined sexual act, real or simulated, in a nonobscene manner. It would also prohibit the sale, showing, or distributing of medical or educational materials containing photographs of such acts. Indeed, by its terms, the statute would prohibit those who oppose such portrayals from providing illustrations of what they oppose.” 52 N. Y. 2d, at 678, 422 N. E. 2d, at 525.
While the construction that a state court gives a state statute is not a matter subject to our review, Wainwright v. Stone, 414 U. S. 21, 22-28 (1973); Gooding v. Wilson, 405 U. S. 518, 520 (1972), this Court is the final arbiter of whether the Federal Constitution necessitated-the invalidation of a state law. It is only through this process of review that we may correct erroneous applications of the Constitution that err on the side of an overly broad reading of our doctrines and precedents, as well as state-court decisions giving the Constitution too little shrift. A state court is not free to avoid a proper facial attack on federal constitutional grounds. Bigelow v. Virginia, 421 U. S. 809, 817 (1975). By the same token, it should not be compelled to entertain an overbreadth attack when not required to do so by the Constitution.
A
The traditional rule is that a person to whom a statute may constitutionally be applied may not challenge that statute on the ground that it may conceivably be applied unconstitutionally to others in situations not before the Court. Broadrick v. Oklahoma, supra, at 610; United States v. Raines, 362 U. S. 17, 21 (1960); Carmichael v. Southern Coal & Coke Co., 301 U. S. 495, 513 (1937); Yazoo & M. V. R. Co. v. Jackson Vinegar Co., 226 U. S. 217, 219-220 (1912). In Broadrick, we recognized that this rule reflects two cardinal principles of our constitutional order: the personal nature of constitutional rights, McGowan v. Maryland, 366 U. S. 420, 429 (1961), and prudential limitations on constitutional adjudication. In United States v. Raines, supra, at 21, we noted the “incontrovertible proposition” that it “‘would indeed be undesirable for this Court to consider every conceivable situation which might possibly arise in the application of complex and comprehensive legislation/” (quoting Barrows v. Jackson, 346 U. S. 249, 256 (1953)). By focusing on the factual situation before us, and similar cases necessary for development of a constitutional rule, we face “flesh-and-blood” legal problems with data “relevant and adequate to an informed judgment.” This practice also fulfills a valuable institutional purpose: it allows state courts the opportunity to construe a law to avoid constitutional infirmities.
What has come to be known as the First Amendment overbreadth doctrine is one of the few exceptions to this principle and must be justified by “weighty countervailing policies.” United States v. Raines, supra, at 22-23. The doctrine is predicated on the sensitive nature of protected expression: “persons whose expression is constitutionally protected may well refrain from exercising their rights for fear of criminal sanctions by a statute susceptible of application to protected expression.” Village of Schaumburg v. Citizens for a Better Environment, 444 U. S. 620, 634 (1980); Gooding v. Wilson, supra, at 521. It is for this reason that we have allowed persons to attack overly broad statutes even though the conduct of the person making the attack is clearly unprotected and could be proscribed by a law drawn with the requisite specificity. Dombrowski v. Pfister, 380 U. S. 479, 486 (1965); Thornhill v. Alabama, 310 U. S. 88, 97-98 (1940); United States v. Raines, supra, at 21-22; Gooding v. Wilson, supra, at 521.
The scope of the First Amendment overbreadth doctrine, like most exceptions to established principles, must be carefully tied to the circumstances in which facial invalidation of a statute is truly warranted. Because of the wide-reaching effects of striking down a statute on its face at the request of one whose own conduct may be punished despite the First Amendment, we have recognized that the overbreadth doctrine is “strong medicine” and have employed it with hesitation, and then “only as a last resort.” Broadrick, 413 U. S., at 613. We have, in consequence, insisted that the over-breadth involved be “substantial” before the statute involved will be invalidated on its face.
In Broadrick, we explained the basis for this requirement:
“[T]he plain import of our cases is, at the very least, that facial overbreadth adjudication is an exception to our traditional rules of practice and that its function, a limited one at the outset, attenuates as the otherwise unprotected behavior that it forbids the State to sanction moves from ‘pure speech’ toward conduct and that conduct — even if expressive — falls within the scope of otherwise valid criminal laws that reflect legitimate state interests in maintaining comprehensive controls over harmful, constitutionally unprotected conduct. Although such laws, if too broadly worded, may deter protected speech to some unknown extent, there comes a point where that effect — at best a prediction — cannot, with confidence, justify invalidating a statute on its face and so prohibiting a State from enforcing the statute against conduct that is admittedly within its power to proscribe. Cf. Alderman v. United States, 394 U. S. 165, 174-175 (1969).” Id., at 615.
We accordingly held that “particularly where conduct and not merely speech is involved, we believe that the overbreadth of a statute must not only be real, but substantial as well, judged in relation to the statute’s plainly legitimate sweep.” Ibid.
Broadrick examined a regulation involving restrictions on political campaign activity, an area not considered “pure speech,” and thus it was unnecessary to consider the proper overbreadth test when a law arguably reaches traditional forms of expression such as books and films. As we intimated in Broadrick, the requirement of substantial over-breadth extended “at the very least” to cases involving conduct plus speech. This case, which poses the question squarely, convinces us that the rationale of Broadrick is sound and should be applied in the present context involving the harmful employment of children to make sexually explicit materials for distribution.
The premise that a law should not be invalidated for overbreadth unless it reaches a substantial number of impermissible applications is hardly novel. On most occasions involving facial invalidation, the Court has stressed the embracing sweep of the statute over protected expression. Indeed, Justice Brennan observed in his dissenting opinion in Broadrick:
“We have never held that a statute should be held invalid on its face merely because it is possible to conceive of a single impermissible application, and in that sense a requirement of substantial overbreadth is already implicit in the doctrine.” Id., at 630.
The requirement of substantial overbreadth is directly derived from the purpose and nature of the doctrine. While a sweeping statute, or one incapable of limitation, has the potential to repeatedly chill the' exercise of expressive activity by many individuals, the extent of deterrence of protected speech can be expected to decrease with the declining reach of the regulation. This observation appears equally applicable to the publication of books and films as it is to activities, such as picketing or participation in election campaigns, which have previously been categorized as involving conduct plus speech. We see no appreciable difference between the position of a publisher or bookseller in doubt as to the reach of New York’s child pornography law and the situation faced by the Oklahoma state employees with respect to that State’s restriction on partisan political activity. Indeed, it could reasonably be argued that the bookseller, with an economic incentive to sell materials that may fall within the statute’s scope, may be less likely to be deterred than the employee who wishes to engage in political campaign activity. Cf. Bates v. State Bar of Arizona, 433 U. S. 350, 380-381 (1977) (overbreadth analysis inapplicable to commercial speech).
This requirement of substantial overbreadth may justifiably be applied to statutory challenges which arise in defense of a criminal prosecution as well as civil enforcement or actions seeking a declaratory judgment. Cf. Parker v. Levy, 417 U. S. 733, 760 (1974). Indeed, the Court’s practice when confronted with ordinary criminal laws that are sought to be applied against protected conduct is not to invalidate the law in toto, but rather to reverse the particular conviction. Cantwell v. Connecticut, 310 U. S. 296 (1940); Edwards v. South Carolina, 372 U. S. 229 (1973). We recognize, however, that the penalty to be imposed is relevant in determining whether demonstrable overbreadth is substantial. We simply hold that the fact that a criminal prohibition is involved does not obviate the need for the inquiry or a priori warrant a finding of substantial overbreadth.
B
Applying these principles, we hold that § 263.15 is not substantially overbroad. We consider this the paradigmatic case of a state statute whose legitimate reach dwarfs its arguably impermissible applications. New York, as we have held, may constitutionally prohibit dissemination of material specified in §263.15. While the reach of the statute is directed at the hard core of child pornography, the Court of Appeals was understandably concerned that some protected expression, ranging from medical textbooks to pictorials in the National Geographic would fall prey to the statute. How often, if ever, it may be necessary to employ children to engage in conduct clearly within the reach of §263.15 in order to produce educational, medical, or artistic works cannot be known with certainty. Yet we seriously doubt, and it has not been suggested, that these arguably impermissible applications of the statute amount to more than a tiny fraction of the materials within the statute’s reach. Nor will we assume that the New York courts will widen the possibly invalid reach of the statute by giving an expansive construction to the proscription on “lewd exhibition[s] of the genitals.” Under these circumstances, §263.15 is “not substantially overbroad and . . . whatever overbreadth may exist should be cured through case-by-case analysis of the fact situations to which its sanctions, assertedly, may not be applied.” Broadrick v. Oklahoma, 413 U. S., at 615-616.
IV
Because § 263.15 is not substantially overbroad, it is unnecessary to consider its application to material that does not depict sexual conduct of a type that New York may restrict consistent with the First Amendment. As applied to Paul Ferber and to others who distribute similar material, the statute does not violate the First Amendment as applied to the States through the Fourteenth. The judgment of the New York Court of Appeals is reversed, and the case is remanded to that court for further proceedings not inconsistent with this opinion.
So ordered.
Justice Blackmun concurs in the result.
“[CJhild pornography and child prostitution have become highly organized, multimillion dollar industries that operate on a nationwide scale.” S. Rep. No. 95-438, p. 5 (1977). One researcher has documented the existence of over 260 different magazines which depict children engaging in sexually explicit conduct. Ibid. “Such magazines depict children, some as young as three to five years of age .... The activities featured range from lewd poses to intercourse, fellatio, cunnilingus, masturbation, rape, incest and sado-masochism.” Id., at 6. In Los Angeles alone, police reported that 30,000 children have been sexually exploited. Sexual Exploitation of Children, Hearings before the Subcommittee on Select Education of the House Committee on Education and Labor, 95th Cong., 1st Sess., 41-42 (1977).
In addition to New York, 19 States have prohibited the dissemination of material depicting children engaged in sexual conduct regardless of whether the material is obscene. Ariz. Rev. Stat.

Four States continue to follow the test approved in Memoirs v. Massachusetts, 383 U. S. 413 (1966). Cal. Penal Code Ann. § 311(a) (West Supp. 1982); Conn. Gen. Stat. §53a-193 (1981); Fla. Stat. §847.07 (1981); Ill. Rev. Stat., ch. 38, ¶ 11-20(b) (1979). Five States regulate only the distribution of pornographic material to minors. Me. Rev. Stat. Ann., Tit. 17, § 2911 (Supp. 1981-1982); Mont. Code Ann. § 45-8-201 (1981); N. M. Stat. Ann. §30-37-2 (Supp. 1982); Vt. Stat. Ann., Tit. 13, §2802 (1974); W. Va. Code § 61-8A-2 (1977). Three state obscenity laws do not fall into any of the above categories. Miss. Code Ann. § 97-29-33 (1973), declared invalid in ABC Interstate Theatres, Inc. v. State, 325 So. 2d 123 (Miss. 1976); Wis. Stat. § 944.21(1)(a) (1979-1980), declared invalid in State v. Princess Cinema of Milwaukee, Inc., 96 Wis. 2d 646, 292 N. W. 2d 807 (1980); Wyo. Stat. § 6-5-303 (1977); Alaska has no current state obscenity law.
A number of States employ a different obscenity standard with respect to material distributed to children. See, e. g., Fla. Stat. § 847.0125 (1981).
In addition, the legislature found “the sale of these movies', magazines and photographs depicting the sexual conduct of children to be so abhorrent to the fabric of our society that it urge[d] law enforcement officers to aggressively seek out and prosecute . . . the peddlers ... of this filth by vigorously applying the sanctions contained in this act.” 1977 N. Y. Laws, ch. 910, § 1.
“[T]he use of children as . . . subjects of pornographic materials is very harmful to both the children and the society as a whole.” S. Rep. No. 95-438, p. 5 (1977). It has been found that sexually exploited children are unable to develop healthy affectionate relationships in later life, have sexual dysfunctions, and have a tendency to become sexual abusers as adults. Schoettle, Child Exploitation: A Study of Child Pornography, 19 J. Am. Acad. Child Psychiatry 289, 296 (1980) (hereafter cited as Child Exploitation); Schoettle, Treatment of the Child Pornography Patient, 137 Am. J. Psychiatry 1109, 1110 (1980); Densen-Gerner, Child Prostitution and Child Pornography: Medical, Legal, and Societal Aspects of the Commercial Exploitation of Children, reprinted in U. S. Dept. of Health and Human Services, Sexual Abuse of Children: Selected Readings 77, 80 (1980) (hereafter cited as Commercial Exploitation) (sexually exploited children predisposed to self-destructive behavior such as drug and alcohol abuse or prostitution). See generally Burgess & Holmstrom, Accessory-to-Sex: Pressure, Sex, and Secrecy, in A. Burgess, A. Groth, L. Holmstrom, & S. Sgroi, Sexual Assault of Children and Adolescents 85, 94 (1978); V. De Francis, Protecting the Child Victim of Sex Crimes Committed by Adults 169 (1969); Ellerstein & Canavan, Sexual Abuse of Boys, 134 Am. J. Diseases of Children 255, 256-257 (1980); Finch, Adult Seduction of the Child: Effects on the Child, Medical Aspects of Human Sexuality 170, 185 (Mar. 1973); Groth, Sexual Trauma in the Life Histories of Rapists and Child Molesters, 4 Victimology 10 (1979). Sexual molestation by adults is often involved in the production of child sexual performances. Sexual Exploitation of Children, A Report to the Illinois General Assembly by the Illinois Legislative Investigating Commission 30-31 (1980). When such performances are recorded and distributed, the child’s privacy interests are also invaded. See n. 10, infra.
“As one authority has explained:
“[Plornography poses an even greater threat to the child victim than does sexual abuse or prostitution. Because the child’s actions are reduced to a recording, the pornography may haunt him in future years, long after the original misdeed took place. A child who has posed for a camera must go through life knowing that the recording is circulating within the mass distribution system for child pornography.” Shouvlin, Preventing the Sexual Exploitation of Children: A Model Act, 17 Wake Forest L. Rev. 535, 545 (1981).
See also Child Exploitation 292 (“[I]t is the fear of exposure and the tension of keeping the act secret that seem to have the most profound emotional repercussions”); Note, Protection of Children from Use in Pornography: Toward Constitutional and Enforceable Legislation, 12 U. Mich. J. Law Reform 295, 301 (1979) (hereafter cited as Use in Pornography) (interview with child psychiatrist) (“The victim’s knowledge of publication of the visual material increases the emotional and psychic harm suffered by the child”).
Thus, distribution of the material violates “the individual interest in avoiding disclosure of personal matters.” Whalen v. Roe, 429 U. S. 589, 599 (1977). Respondent cannot undermine the force of the privacy interests involved here by looking to Cox Broadcasting Corp. v. Cohn, 420 U. S. 469 (1975), and Smith v. Daily Mail Publishing Co., 443 U. S. 97 (1979), cases protecting the right of newspapers to publish, respectively, the identity of a rape victim and a youth charged as a juvenile offender. Those cases only stand for the proposition that “if a newspaper lawfully obtains truthful information about a matter of public significance then state officials may not constitutionally punish publication of the information, absent a need ... of the highest order.” Id., at 103.
See Sexual Exploitation of Children, Hearings before the Subcommittee on Crime of the House Judiciary Committee, 95th Cong., 1st Sess., 34 (1977) (statement of Charles Rembar) (“It is an impossible prosecutorial job to try to get at the acts themselves”); id., at 11 (statement of Frank Osanka, Professor of Social Justice and Sociology) (“[W]e have to be very careful. . . that we don’t take comfort in the existence of statutes that are on the books in the connection with the use of children in pornography .... There are usually no witnesses to these acts of producing pornography”); id., at 69 (statement of Investigator Lloyd Martin, Los Angeles Police Department) (producers of child pornography use false names making difficult the tracing of material back from distributor). See also L. Tribe, American Constitutional Law 666, n. 62 (1978); Note, Child Pornography: A New Role for the Obscenity Doctrine, 1978 U. Ill. Law Forum 711, 716, n. 29; Use in Pornography 315 (“passage of criminal laws aimed at producers without similar regulation of distributors will arguably shift the production process further underground”).
In addition, legal obscenity under Miller is a function of “contemporary community standards.” 413 U. S., at 24. “It is neither realistic nor constitutionally sound to read the First Amendment as requiring that the people of Maine or Mississippi accept public depiction of conduct found tolerable in Las Vegas, or New York City.” Id., at 32. It would be equally unrealistic to equate a community’s toleration for sexually oriented material with the permissible scope of legislation aimed at protecting children from sexual exploitation. Furthermore, a number of States rely on stricter obscenity tests, see n. 7, supra, under which successful prosecution for child pornography may be even more difficult.
One state committee studying the problem declared: “The act of selling these materials is guaranteeing that there will be additional abuse of children.” Texas House Select Committee on Child Pornography: Its Related Causes and Control 132 (1978). See also Commercial Exploitation 80 (“Printed materials cannot be isolated or removed from the process involved in developing them”).
“In Giboney, a unanimous Court held that labor unions could be restrained from picketing a firm in support of a secondary boycott which a State had validly outlawed. In Pittsburgh Press Co. v. Pittsburgh Comm’n on Human Relations, 413 U. S. 376 (1973), the Court allowed an injunction against a newspaper’s furtherance of illegal sex discrimination by placing of job advertisements in gender-designated columns. The Court stated:
“Any First Amendment interest which might be served by advertising an ordinary commercial proposal and which might arguably outweigh the governmental interest supporting the regulation is altogether absent when the commercial activity itself is illegal and the restriction on advertising is incidental to a valid limitation on economic activity.” Id., at 389.
In this connection we note that 18 U. S. C. § 2251 (1976 ed., Supp. IV), making it a federal offense for anyone to use children under the age of 16 in the production of pornographic materials, embraces all “sexually explicit conduct” without imposing an obscenity test. In addition, half of the state laws imposing criminal liability on the producer do not require the visual material to be legally obscene. Use in Pornography 307-308.
96 Misc. 2d, at 676, 409 N. Y. S. 2d, at 637. This is not merely a hypothetical possibility. See Brief for Petitioner 25 and examples cited therein.
Sixteen States define a child as a person under age 18. Four States define a child as under 17 years old. The federal law and 16 States, including New York, define a child as under 16. Illinois and Nebraska define a child as a person under age 16 or who appears as a prepubescent. Ill. Rev. Stat., ch. 38, ¶ 11-20a(a)(1)(A) (1979); Neb. Rev. Stat. §28-1463 (1979). Indiana defines a child as one who is or appears to be under 16. Ind. Code. §§ 35-30-10.1-2, 35-30-10.1-3 (1979). Kentucky provides for two age classifications (16 and 18) and varies punishment according to the victim’s age. Ky. Rev. Stat. §§ 531.300-531.370 (Supp. 1980). See Use in Pornography 307, n. 71 (collecting statutes).
Erznoznik v. City of Jacksonville, 422 U. S. 205 (1975), relied upon by the Court of Appeals, struck down a law against drive-in theaters showing nude scenes if movies could be seen from a public place. Since nudity, without more is protected expression, id,., at 213, we proceeded to consider the underinelusiveness of the ordinance. The Jacksonville ordinance impermissibly singled out movies with nudity for special treatment while failing to regulate other protected speech which created the same alleged risk to traffic. Today, we hold that child pornography as defined in § 263.15 is unprotected speech subject to content-based regulation. Hence, it cannot be underinclusive or unconstitutional for a State to do precisely that.
It is often impossible to determine where such material is produced. The Senate Report accompanying federal child pornography legislation stressed that “it is quite common for photographs or films made in the United States to be sent to foreign countries to be reproduced and then returned to this country in order to give the impression of foreign origin.” S. Rep. No. 95 — 438, p. 6 (1977). In addition, States have not limited their distribution laws to material produced within their own borders because the maintenance of the market itself “leaves open the financial conduit by which the production of such material is funded and materially increases the risk that [local] children will be injured.” 52 N. Y. 2d 674, 688, 422 N. E. 2d 523, 531 (1981) (Jasen, J., dissenting).
In addition to prudential restraints, the traditional rule is grounded in Art. Ill limits on the jurisdiction of federal courts to actual cases and controversies.
“This Court, as is the case with all federal courts, ‘has no jurisdiction to pronounce any statute, either of a State or of the United States, void, because irreconcilable with the Constitution, except as it is called upon to adjudge the legal rights of litigants in actual controversies. In the exercise of that jurisdiction, it is bound by two rules, to which it has rigidly adhered, one, never to anticipate a question of constitutional law in advance of the necessity of deciding it; the other never to formulate a rule of constitutional law broader than is required by the precise facts to which it is to be applied.’ Liverpool, New York & Philadelphia S.S. Co. v. Commissioners of Emigration, 113 U. S. 33, 39.” United States v. Raines, 362 U. S. 17, 21 (1960).
Overbreadth challenges are only one type of facial attack. A person whose activity may be constitutionally regulated nevertheless may argue that the statute under which he is convicted or regulated is invalid on its face. See, e. g., Terminiello v. City of Chicago, 337 U. S. 1, 5 (1949). See generally Monaghan, Overbreadth, 1981 S. Ct. Rev. 1, 10-14.
A. Bickel, The Least Dangerous Branch 115-116 (1962).
Frankfurter & Hart, The Business of the Supreme Court at October Term, 1934, 49 Harv. L. Rev. 68, 95-96 (1935).
“When a federal court is dealing with a federal statute challenged as overbroad, it should, of course, construe the statute to avoid constitutional problems, if the statute is subject to such a limiting construction. Crowell v. Benson, 285 U. S. 22, 62 (1932). Accord, e. g., Haynes v. United States, 390 U. S. 85, 92 (1968) (dictum); Schneider v. Smith, 390 U. S. 17, 27 (1968); United States v. Rumely, 345 U. S. 41, 45 (1953); Ashwander v. TVA, 297 U. S. 288, 348 (1936) (Brandeis, J., concurring). Furthermore, if the federal statute is not subject to a narrowing construction and is impermissibly overbroad, it nevertheless should not be stricken down on its face; if it is severable, only the unconstitutional portion is to be invalidated. United States v. Thirty-seven Photographs, 402 U. S. 363 (1971).
A state court is also free to deal with a state statute in the same way. If the invalid reach of the law is cured, there is no longer reason for proscribing the statute’s application to unprotected conduct. Here, of course, we are dealing with a state statute on direct review of a state-court decision that has construed the statute. ■ Such a construction is binding on us.
Parker v. Levy, 417 U. S. 733, 760 (1974) (“This Court has . . . repeatedly expressed its reluctance to strike down a statute on its face where there were a substantial number of situations to which it might be validly applied. Thus, even if there are marginal applications in which a statute would infringe on First Amendment values, facial invalidation is inappropriate if the ‘remainder of the statute . . . covers a whole range of easily identifiable and constitutionally proscribable . . . conduct . . . .’ CSC v. Letter Carriers, 413 U. S. 548, 580-581 (1973)”). See Bogen, First Amendment Ancillary Doctrines, 37 Md. L. Rev. 679, 712-714 (1978); Note, The First Amendment Overbreadth Doctrine, 83 Harv. L. Rev. 844, 860-861 (1970).
In Gooding v. Wilson, 405 U. S. 518, 519, 527 (1972), the Court’s invalidation of a Georgia statute making it a misdemeanor to use “ ‘opprobrious words or abusive language, tending to cause a breach of the peace’ ” followed from state judicial decisions indicating that “merely to speak words offensive to some who hear them” could constitute a “breach of the peace.” Cases invalidating laws requiring members of a “subversive organization” to take a loyalty oath, Baggett v. Bullitt, 377 U. S. 360 (1964), or register with the government, Dombrowski v. Pfister, 380 U. S. 479 (1965), can be explained on the basis that the laws involved, unlike §263.15, defined no central core of constitutionally regulable conduct; the entire scope of the laws was subject to the uncertainties and vagaries of prosecutorial discretion. See also Bigelow v. Virginia, 421 U. S. 809, 817 (1975) (“the facts of this case well illustrate ‘the statute’s potential for sweeping and improper applications’”) (citation omitted); NAACP v. Button, 371 U. S. 415, 433 (1963) (“We read the decree of the Virginia Supreme Court of Appeals . . . as proscribing any arrangement by which prospective litigants are advised to seek the assistance of particular attorneys”); Thornhill v. Alabama, 310 U. S. 88, 97 (1940) (the statute “does not aim specifically at evils within the allowable area of state control but, on the contrary, sweeps within its ambit other activities that in ordinary circumstances constitute an exercise of freedom of speech or of the press”).
“A substantial overbreadth rule is implicit in the chilling effect rationale. . . . [T]he presumption must be that only substantially overbroad laws set up the kind and degree of chill that is judicially cognizable.” Moreover, “[wjithout a substantial overbreadth limitation, review for over-breadth would be draconian indeed. It is difficult to think of a law that is utterly devoid of potential for unconstitutionality in some conceivable application.” Note, 83 Harv. L. Rev., supra n. 25, at 859, and n. 61.
There is no argument that the films sold by respondent do not fall squarely within the category of activity we have defined as unprotected. Therefore, no independent examination of the material is necessary to assure ourselves that the judgment here “does not constitute a forbidden intrusion on the field of free expression.” New York Times Co. v. Sullivan, 376 U. S. 254, 285 (1964).
What follows is an opinion from the Supreme Court of the United States. Your task is to determine the bases on which the Supreme Court rested its decision with regard to the legal provision that the Court considered in the case. Consider "judicial review (national level)" if the majority determined the constitutionality of some action taken by some unit or official of the federal government, including an interstate compact. Consider "judicial review (state level)" if the majority determined the constitutionality of some action taken by some unit or official of a state or local government. Consider "statutory construction" for cases where the majority interpret a federal statute, treaty, or court rule; if the Court interprets a federal statute governing the powers or jurisdiction of a federal court; if the Court construes a state law as incompatible with a federal law; or if an administrative official interprets a federal statute. Do not consider "statutory construction" where an administrative agency or official acts "pursuant to" a statute, unless the Court interprets the statute to determine if administrative action is proper. Consider "interpretation of administrative regulation or rule, or executive order" if the majority treats federal administrative action in arriving at its decision.Consider "diversity jurisdiction" if the majority said in approximately so many words that under its diversity jurisdiction it is interpreting state law. Consider "federal common law" if the majority indicate that it used a judge-made "doctrine" or "rule; if the Court without more merely specifies the disposition the Court has made of the case and cites one or more of its own previously decided cases unless the citation is qualified by the word "see."; if the case concerns admiralty or maritime law, or some other aspect of the law of nations other than a treaty; if the case concerns the retroactive application of a constitutional provision or a previous decision of the Court; if the case concerns an exclusionary rule, the harmless error rule (though not the statute), the abstention doctrine, comity, res judicata, or collateral estoppel; or if the case concerns a "rule" or "doctrine" that is not specified as related to or connected with a constitutional or statutory provision. Consider "Supreme Court supervision of lower federal or state courts or original jurisdiction" otherwise (i.e., the residual code); for issues pertaining to non-statutorily based Judicial Power topics; for cases arising under the Court's original jurisdiction; in cases in which the Court denied or dismissed the petition for review or where the decision of a lower court is affirmed by a tie vote; or in workers' compensation litigation involving statutory interpretation and, in addition, a discussion of jury determination and/or the sufficiency of the evidence.
