Americans have been highly mobile people. Describe and account for the dominant Population Movements between 1820 and 1900.

Beginning in the 1880s, an era of qualitative immigration restrictions began as certain types of immigrants were barred: prostitutes, workers with contracts that tied them to a particular employer for several years, and Chinese. In the 1920s, quantitative restrictions or quotas set a ceiling on the number of immigrants accepted each year.2

Immigration law changed in 1965. Qualitative and quantitative restrictions were maintained, but national origin preferences that favored the entry of Europeans were dropped. U.S. immigration policy began to favor the entry of foreigners who had U.S. relatives and foreigners requested by U.S. employers. During the 1970s, the origins of most immigrants changed from Europe to Latin America and Asia: U.S. immigration has occurred in waves, with peaks followed by troughs (see figure). The first wave of immigrants, mostly English-speakers from the British Isles, arrived before records were kept beginning in 1820. The second wave, dominated by Irish and German Catholics in the 1840s and 1850s, challenged the dominance of the Protestant church and led to a backlash against Catholics, defused only when the Civil War practically stopped immigration in the 1860s.

The third wave, between 1880 and 1914, brought over 20 million European immigrants to the United States, an average of 650,000 a year at a time when the United States had 75 million residents. Most southern and eastern European immigrants arriving via New York’s Ellis Island found factory jobs in Northeastern and Midwestern cities. Third-wave European immigration was slowed first by World War I and then by numerical quotas in the 1920s.
