The U.S. population grew just 0.1 percent in 2021, the slowest rate since the nation was founded in the 18th century, according to data from the U.S. Census Bureau.
The Census Bureau attributed the slow population growth to the Covid-19 pandemic, though the country has been experiencing low birth rates for several years. Low population growth in recent years has historically been attributed to simultaneously rising death rates of an aging U.S. population and falling declining rates in both births and migration.
Studies showed that net migration from Puerto Rico and foreign countries declined during the Covid-19 pandemic.
