To America in the Twentieth Century
(numbers in millions)
14.53 million - Fueled by relative prosperity at home and a world war and economic turmoil abroad, immigration to the U.S. exploded during the first 20 years, the biggest influx to date.
4.6 million - Although immigration remained strong during the Roaring '20s, the Great Depression of the '30s quickly trimmed the flow of immigrants down as jobs and wealth became scarce in the U.S.
3.55 million - Immigration rose slightly during WWII but not to pre-Depression levels. The Cold War of the '50s kept these rates low.
7.8 million - Two decades of strong job growth in the U.S. were enough to boost the immigration rate to pre-Depression levels.
