A 10-year immigration ban? Here’s the impact that would have on the U.S. population.

We can use Census Bureau data from 2010 and 2019 to show how immigration and population growth are related. Over that period, the population increased in 47 states; the exceptions being Connecticut, Illinois, Vermont and West Virginia. (They are indicated with small orange arrows below.) Take out growth from foreign-born residents, and five additional states would have grown smaller: Michigan, New Jersey, New York, Pennsylvania and Rhode Island.
