Immigration is essential to counter sharp declines in growthJust how much do different immigration levels affect future U.S. population growth?
The other three scenarios are: 1) a “high immigration” scenario, which assumes a 50% increase in immigration going forward; 2) a “low immigration” scenario, which assumes a roughly 50% decrease; and 3) a “zero immigration” scenario, which assumes no new immigration to the U.S., but does allow for out-migration from the country.
The “main” immigration scenario would lead to population growth of 22%, from 333 million to 404 million.
With a rapidly aging native-born population, immigration will ensure growth—especially among the youth and labor force populations.
It is also important to note that the nation will continue to become more racially and ethnically diverse under all immigration scenarios.
