Demographic history of New York City



The racial and ethnic history of New York City has varied widely; from its sale to the Dutch by Native American residents, to the modern multi-cultural period. New York City has had a largely white population, and most foreign born immigrants to the city before the end of World War II were from Europe. However, this changed in the decades after World War II, when all of the boroughs became more  diverse, and when immigration from places outside Europe was increased largely due to the Immigration and Nationality Act of 1965.

Overview
The population of New York City was over 90% Non-Hispanic White until the post-World War II era. Large numbers of Blacks, Hispanics, or Asians began settling in Manhattan in the 1920s and in the rest of NYC after World War II. The slowest area in the city to change its racial makeup was Staten Island, which was the only borough of New York City to retain a Non-Hispanic White majority after the 1980s. Between 1900 and 2010, New York City's total Black population increased by about thirty-five times, while its Asian population increased by over one-hundred-and-fifty times over the same period. The large Black migration to New York City helped cause the Harlem Renaissance, a rich cultural period for the African Americans living in New York (especially in Harlem neighborhood, the namesake) between the end of World War I and the Great Depression. New York's Hispanic population increased by almost twenty times between 1940 and 2010, while its total Non-Hispanic White population decreased by over 60% over the same time period.

New York's five boroughs have had different settlement histories. The Bronx and Brooklyn were the most popular destinations for Blacks to settle, while Queens was the most popular destination for Asian migrants to NYC and the Bronx was the most popular destination for Hispanic migrants to move to. New York City's total population more than doubled between 1900 and 2010 (with a period of population stagnation between 1950 and 1990). The Bronx, Queens, and Staten Island experienced enormous population growth between 1900 and 2010, much higher than New York's average population growth. Brooklyn's population grew at a much slower rate during this time period, while Manhattan actually had fewer people in 2010 than in 1900.

New York City has always had a much greater percentage of immigrants as part of its total population than the whole United States has. Right before World War I over 40% of New York City's total population was composed of immigrants. After immigration restrictions were passed in the 1920s, immigrants as a percentage of New York's total population dropped to 18% in 1970, before rebounding back up to 36% in 2000. The recorded increase in the city's immigrant percentage after 1970 occurred after the passage of the Immigration Act of 1965 (which took effect in 1968) and at a time when a greater number of immigrants than before were coming to the United States. Most of the earlier immigrants to New York City were from Europe (initially from Western Europe, and then more from Eastern Europe). A large percentage of the immigrants that came to New York City after 1965 were from non-European countries. Large numbers of Irish people arrived in New York City during the Great Famine in the 1840s, while Germans, Italians, Jews, and other European ethnic groups arrived in NYC mostly during the late 19th and early 20th centuries. Because of the abolition of the National Origins Formula, a large percentage of the immigrants that came to New York City after 1965 were from non-European countries. Of the immigrants in the state, about three million live in New York City. The number of immigrants living in New York City increased only slightly from 2000 to 2011, with an increase from 2,871,032 to 3,066,599 residents being born outside the United States.

Citywide
During the early 20th century, from 1900 to 1940, New York City's population was predominantly White, accounting for over 93% of the population, with the Black community constituting less than 3%. By the 1950s, the White population decreased to around 90%, while the Black population increased to nearly 10%. From 1970 to 1980, more pronounced shifts occurred, with the White population dropping to 60.72%, the Black population increasing to 25.23%, and a notable rise in the Hispanic/Latino population to 19.88%. The 1990s brought further diversification, with the White population falling to 44.66% by 2000, and growth in the Black, Asian, and Hispanic/Latino populations. The most recent decade from 2010 to 2020 saw a continued decrease in the White population to 34.09%, significant growth in the Asian population to 15.73%, stability in the Black population around 22-25%, and growth in the Hispanic/Latino community to 28.29%. The Other or Mixed category also grew to 28.11%. Throughout this period, New York City remained a hub for immigrants, with the foreign-born population peaking at 37.51% in 2010. Overall, these trends reflect the transformation of New York City into an increasingly multicultural metropolis, with a progressive decline in the White population and expanding representation of Black, Asian, Hispanic/Latino, and Other or Mixed groups. Foreign-born population data from 2020 Census not yet available (as of Sept 2021).

Brooklyn
In the early 1900s, Brooklyn was predominantly White, with the White population comprising 98.31% in 1900 and staying above 98% through 1920. The Black population was very small at this time, constituting only 1.57% in 1900, while the Asian population was even smaller at 0.11%.

The 1930s started to see a slight decline in the White population, dropping to 97.20%, and the Black population began to grow, reaching 2.69% by 1930. The Asian population remained negligible.

From the 1940s to the 1960s, the decline in the White population became more pronounced, dropping to 92.22% in 1950 and then to 85.48% in 1960. During this period, the Black population increased to 14.14%, and the Asian population began to grow, albeit slowly.

The 1970s and 1980s marked a significant shift in Brooklyn's demographics. The White population fell to 73.24% in 1970 and then sharply to 56.01% in 1980. The Black population increased to 25.22% in 1970 and 32.40% in 1980. The Asian community and Other or Mixed category became more substantial, reaching 1.93% and 9.67%, respectively, in 1980. The Hispanic/Latino community grew to 17.58%, and the foreign-born population remained relatively high, at 23.80% in 1980.

In the last three decades, from 1990 to 2010, Brooklyn's racial and ethnic diversity expanded further. The White population declined to below half of the total, reaching 42.80% in 2010, while the Black population remained around 34-37%. The Asian population increased significantly to 10.52% by 2010, and the Other or Mixed category reached 12.34%. The Hispanic/Latino population hovered around 19-20%, and the foreign-born population grew to 36.44% in 2010.

Manhattan
The demographic landscape of Manhattan has shifted considerably over the past century. In 1900, the borough was overwhelmingly White, with a White population that constituted 97.78% of the total, while Black residents made up only 1.96%. Over the subsequent decades, the proportion of White residents gradually decreased, falling to 94.96% in 1920 and then more sharply to 87.47% in 1930. The Black population simultaneously grew to 12.03% in 1930.

From the 1940s through the 1960s, the decline in the White population continued, with percentages dropping to 79.41% in 1950 and 74.89% in 1960. During this period, the Black population increased to nearly one-quarter of the total, reaching 23.38% in 1960. Additionally, the Asian population began to grow, reaching 1.50% in 1960.

The 1970s and 1980s marked a significant transformation in Manhattan's racial composition. The White population fell below 60%, reaching 58.90% in 1980, while the Black population stabilized around 20-25%. The Asian community continued to grow, reaching 5.10% in 1980, and the Other or Mixed category emerged as a more substantial portion of the population, making up 14.31% in 1980. The Hispanic/Latino community also became more prominent, growing to 23.54% in 1980.

In recent decades, from 1990 to 2010, the racial diversity in Manhattan has continued to expand. The White population remained around 57-58%, while the Black population fluctuated around 15-17%. The Asian population grew to 11.38% by 2010, and the Other or Mixed category increased to 15.62%. The Hispanic/Latino population remained significant, at 25.45% in 2010, and the foreign-born population has been consistently high, reaching 29.66% in 2010.
