Percent Change in the Total and Foreign-born Populations
New York City, 1900 to 2023
Throughout its history, New York City’s population has been shaped by the ebb and flow of immigrants. European immigration helped fuel dramatic population growth in the initial decades of the 1900s and, in the latter half of the century, the city’s population was reshaped by the Immigration and Nationality Act of 1965 (also known as the Hart-Celler Act). This pivotal legislation repealed immigration quotas that favored northern and western Europeans and established a fairer system for all countries, resulting in a large increase in immigrants from other parts of the world. These new sources of immigration helped change the racial and ethnic make-up of the city. This chapter first examines the overall growth of New York’s population since the turn of the last century and shows how immigration has long fueled the city’s population growth and, later in the century, stemmed its decline. It next examines the top immigrant groups in 2023 and goes on to analyze the changing composition of the city’s immigrant population since 1970, the period that was directly affected by the 1965 law and subsequent amendments. Data throughout this chapter are from U.S. decennial censuses and the American Community Survey.
New York’s population grew for most of the 20th century and for the first two decades of the 21st century (Table 2.1 and Figure 2.1). Following the 1898 consolidation of the five boroughs, the city’s population stood at 3.4 million in 1900. Population growth, largely fueled by immigration, was highest in the first decade of the 20th century, with the city’s population increasing 38.7 percent, reaching 4.8 million in 1910. Continued immigration, domestic inflows, and natural increase (births minus deaths) resulted in further large increases, with the city reaching 6.9 million in 1930, doubling in size in just three decades.
With the onset of the Great Depression and World War II, as well as restrictive national immigration policies in place at the time, immigration tapered off in the 1930s and 1940s, but the city continued to grow due to domestic flows from the South and from Puerto Rico. By 1950, the city’s population had reached 7.9 million. High Baby Boom fertility and domestic inflows in the 1950s did not fully counter the large out-migration to the suburbs, and growth dipped during this period. With the enactment of the 1965 Immigration and Nationality Act, immigration increased once again, and by 1970 the city’s population rebounded to its 1950 high of 7.9 million.
The substantial increase in immigration in the 1970s was insufficient to offset the very large domestic outflow during the decade. As a result, the city’s population declined by 10.4 percent, to 7.1 million in 1980. Lower domestic out-migration in the 1980s, a higher level of immigration, and greater natural increase all resulted in a return to growth, with the city’s population enumerated at 7.3 million in 1990. With continued growth in the 1990s, the city’s population surpassed 8 million for the first time in 2000.
Over a decade later, the city’s population had increased to 8.4 million in 2013 and reached an all-time high of 8.8 million in 2020. The outbreak of Covid-19 at the start of the third decade of the 21st century produced steep declines, resulting in the city’s population dipping to 8.4 million by 2023.1 It has since increased to 8.5 million in 2024 as domestic outflows moderated and international flows to the city increased.
The U.S. Census Bureau’s American Community Survey (ACS) provides detailed information on the place of birth of city residents. Respondents who wrote-in a place of birth outside the United States and its territories, and whose parents were not American citizens, are included in the foreign-born population.2 The overwhelming share of the foreign-born are lawful immigrants, i.e., persons who were at one time admitted to the United States for lawful permanent residence under the provisions of the Immigration and Nationality Act. The foreign-born population, however, also includes non-immigrants, such as students, business personnel, and diplomats, who have been admitted to the United States for a temporary duration. The foreign-born also includes unauthorized immigrants. In this study, we use the terms foreign-born and immigrants interchangeably.
The 2023 ACS, which is the primary source of data for this report, does not fully reflect the foreign-born population in New York City, in part due to an underestimate of migration at the national level. It also does not accurately reflect all migrants and asylum seekers who arrived in 2022 and 2023 who were living in temporary shelters. A methodological update was integrated into the 2024 estimates which improved estimates of international migration, and the Census Bureau also incorporated data provided by the city on the increase in migrants and asylum seekers in temporary shelters. The result of these improvements was an upward revision of 133,000 to the estimate of New York City’s population as of July 2023, largely attributable to the influx of migrants. Updated figures for the total and foreign-born populations will be reflected in the 2024 ACS data.
The foreign-born population totaled 1.3 million in 1900 and increased by 674,000 to reach 1.9 million by the end of the decade. Both the increase in the foreign-born (53.1 percent) and the foreign-born share of the 1910 population (40.8 percent) have been unmatched in subsequent decades. This large increase was due to a wave of immigration from southern and eastern Europe, which continued into the early 1920s. Although restrictive immigration policies slowed inflows in the latter half of the 1920s, New York City’s foreign-born population still reached a new peak of 2.4 million by 1930. However, the sharp decline in immigration during the Great Depression and World War II led to a sustained reduction in the foreign-born population over the following four decades, reaching a low of 1.4 million by 1970. Changes in immigration law in 1965 resulted in a resurgence in immigration, and the foreign-born population rose in the following decades. The largest absolute increase in the foreign-born population occurred in the 1990s, with 788,000 foreign-born added to the population, which helped establish a new peak of 2.9 million foreign-born New Yorkers in 2000. Thus, the first and last decades of the century were bookends to the largest increases in the city’s foreign-born. Growth slowed substantially in the new century, with the foreign-born population increasing to over 3.1 million in 2013, and remaining roughly the same in 2023. The foreign-born comprised 37.5 percent of the city’s population in 2023, compared to their 14.3 percent share of the U.S. population.
At the turn of the last century, New York City was home to 12.3 percent (Figure 2.2) of the nation’s foreign-born population of 10.3 million. With southern and eastern European immigrants settling disproportionately in New York, the city’s share of the U.S. foreign-born population increased in the next four decades, reaching 18.4 percent in 1940. As immigration waned, and many longer-resident immigrants out-migrated from New York, the city’s share of the nation’s foreign-born population began to decline. By 1970, under 15 percent of the country’s foreign-born made their home in New York City. While immigration to the city rebounded after the passage of the 1965 Immigration and Nationality Act, flows to the United States as a whole increased even faster, as Mexicans and most Asian groups settled largely on the West Coast. By 2023, just 6.5 percent of the U.S. foreign-born lived in New York City. This still represented a disproportionate share of the nation’s foreign-born, given that the city accounted for under 2.5 percent of the U.S. population in 2023.
In order to get a broad picture of the foreign-born from around the globe, Figure 2.3 divides the world into six “areas of origin”: Latin America, Asia, the non-Hispanic Caribbean,3 Europe, Africa, and an “All Other Areas” category, while Figure 2.4 shows the areas of origin of the 2023 foreign-born population in New York City and the United States.
Latin America was the top area of origin in New York City, accounting for nearly one-third of the city’s immigrants. While this represented a substantial share locally, Latin Americans comprised an even larger portion of the nation’s foreign-born, at 46 percent. Asian immigrants comprised 30 percent of the city’s foreign-born—a proportion that closely mirrored their 31 percent share nationwide. In contrast with Latin Americans and Asians, immigrants from the non-Hispanic Caribbean disproportionately made their home in New York City where they accounted for 17 percent of the foreign-born population, but comprised just 5 percent of the nation’s immigrants. Europeans were also over-represented in New York, accounting for 14 percent of the city’s immigrants, exceeding their 10 percent share of the nation’s foreign-born. Africans comprised the smallest share of the city’s immigrants (just over 5 percent), similar to their nearly 6 percent share of the U.S. foreign-born.
