Premarital sex
Safe sex practices

Sexual activity among unmarried people who do not have access to information about reproductive health and birth control can increase the rate of teenage pregnancies and contraction of sexually transmitted infections. The rates of teenage pregnancy vary and range from 143 per 1000 girls in some sub-Saharan African countries to 2.9 per 1000 girls in South Korea. The rate for the United States is 52.1 per 1000, the highest in the developed world, and about four times the European Union average. The teenage pregnancy rates between countries must take into account the level of general sex education available and access to contraceptive options.
