Ancestry

According to the 2020 United States Census, Hawaii had a population of 1,455,271. The state's population identified as 37.2% Asian; 25.3% Multiracial; 22.9% White; 10.8% Native Hawaiians and other Pacific Islanders; 9.5% Hispanic and Latinos of any race; 1.6% Black or African American; 1.8% from some other race; and 0.3% Native American and Alaskan Native.

Hawaii has the highest percentage of Asian Americans and multiracial Americans and the lowest percentage of White Americans of any state. It is the only state where people who identify as Asian Americans are the largest ethnic group. In 2012, 14.5% of the resident population under age 1 was non-Hispanic white. Hawaii's Asian population consists mainly of 198,000 (14.6%) Filipino Americans, 185,000 (13.6%) Japanese Americans, roughly 55,000 (4.0%) Chinese Americans, and 24,000 (1.8%) Korean Americans.

Over 120,000 (8.8%) Hispanic and Latino Americans live in Hawaii. Mexican Americans number over 35,000 (2.6%); Puerto Ricans exceed 44,000 (3.2%). Multiracial Americans constitute almost 25% of Hawaii's population, exceeding 320,000 people. Hawaii is the only state to have a tri-racial group as its largest multiracial group, one that includes white, Asian and Native Hawaiian/Pacific Islander (22% of all mutiracial population). The non-Hispanic White population numbers around 310,000—just over 20% of the population. The multi-racial population outnumbers the non-Hispanic white population by about 10,000 people. In 1970, the Census Bureau reported Hawaii's population was 38.8% white and 57.7% Asian and Pacific Islander.

There are more than 80,000 Indigenous Hawaiians—5.9% of the population. Including those with partial ancestry, Samoan Americans constitute 2.8% of Hawaii's population, and Tongan Americans constitute 0.6%.

The five largest European ancestries in Hawaii are German (7.4%), Irish (5.2%), English (4.6%), Portuguese (4.3%) and Italian (2.7%). About 82.2% of the state's residents were born in the United States. Roughly 75% of foreign-born residents originate from Asia. Hawaii is a majority-minority state. It was expected to be one of three states that would not have a non-Hispanic white plurality in 2014; the other two are California and New Mexico.

The third group of foreigners to arrive in Hawaii were from China. Chinese workers on Western trading ships settled in Hawaii starting in 1789. In 1820, the first American missionaries arrived to preach Christianity and teach the Hawaiians Western ways. As of 2015, a large proportion of Hawaii's population have Asian ancestry—especially Filipino, Japanese and Chinese. Many are descendants of immigrants brought to work on the sugarcane plantations in the mid-to-late 19th century. The first 153 Japanese immigrants arrived in Hawaii on June 19, 1868. They were not approved by the then-current Japanese government because the contract was between a broker and the Tokugawa shogunate —by then replaced by the Meiji Restoration. The first Japanese current-government-approved immigrants arrived on February 9, 1885, after Kalākaua's petition to Emperor Meiji when Kalākaua visited Japan in 1881.

Almost 13,000 Portuguese migrants had arrived by 1899; they also worked on the sugarcane plantations. By 1901, more than 5,000 Puerto Ricans were living in Hawaii.
