The Johnson-Reed Act was a eugenics-inspired federal law designed to limit the number of immigrants allowed into the United States through a national origins or race-based quota. The quota provided immigration visas to 2% of the total number of people of each nationality in the United States as of the 1890 national census. It completely excluded immigrants from Asia.

This chart allows you to see the impact of a 2% quota restriction across several different census years. A few nationalities have been selected, but all immigrant groups were affected by the Johnson-Reed Act.
