Has America's foreign-born share risen above its previous historical peak?
Core argument: America's foreign-born population surpassed 50 million for the first time in 2024, according to Current Population Survey estimates.
In 2024, according to CPS estimates, America’s total foreign-born population surpassed the 50 million mark for the first time. No less significant, the CPS series indicates that the foreign-born now exceed 15% of the national population for the first time since such figures were first collected (in the 1850 census). The previous high water mark for percentage of foreign-born was in 1890—during what we might call America’s first wave of mass immigration, when the fraction peaked at 14.8%. The immigration restrictions enacted in the 1920s reflected the deep unpopularity of mass immigration at that time among influential political constituencies. Strong anti-immigration sentiment had been evident in America since at least the 1890s; sweeping national restrictions on immigration were very nearly enacted in 1905. Mass immigration was associated in the contemporary mentality with the widening income and wealth gaps and depressed wages for less skilled native-born men that characterized the First Gilded Age. It is a reminder that stringent curbs on immigration have occurred in the USA before.
