History of Immigration From the 1850s to the Present

For example, in 1914 (the peak year of immigration for that era), 1.2 million immigrants arrived. In 1991 (the peak year of the new immigration), 1.8 million immigrants came. But this comparison is somewhat misleading. In 1914, the population of the United States was 99 million compared to 252 million in 1991. ................
