Do periods of high immigration tend to be followed by restrictions?
Core argument: America's foreign-born population share reached nearly 15% in 1890, a threshold not surpassed again until the mid-2020s, before falling to around 5% by 1970.
After periods of high immigration, restrictions have tended to follow. In 1890 the foreign-born share of America’s population reached nearly 15% (a threshold that would not be surpassed until the mid 2020s). The Chinese Exclusion Act of 1882 banned Chinese labourers from immigrating to America for ten years, the first federal law to restrict immigration explicitly based on race or nationality. In 1924 Congress capped annual arrivals from Europe to just 2% of each nationality’s population residing in America at the time of the 1890 census, and banned immigration from Asia outright. These quotas suppressed immigration for 40 years and prevented America from accepting thousands of Jewish refugees fleeing Nazi Europe. By 1970 America’s foreign-born population had fallen to around 5%.
