This post was updated on April 18, 2022 to correct the data point related to international migration in 2020-21 (244,622).
America’s population size is standing still, according to new data from the U.S. Census Bureau. Population growth over the 12-month period from July 1, 2020 through July 1, 2021 stood at unprecedented low of just 0.12%. This is the lowest annual growth since the Bureau began collecting such statistics in 1900, and reflects how all components of population change—deaths, births, and immigration levels—were impacted during a period when the COVID-19 pandemic became most prevalent.[i]
The new estimates show that during this period, population growth declined from the previous year in 31 of 50 states as well as Washington, D.C., with 18 states sustaining absolute population losses. In some states, especially California and New York, population losses were exacerbated by inflated out-migration during the pandemic, just as other states such as Florida and Texas benefitted from greater population in-flows.
While COVID-19 clearly played a role in this near-zero population growth, that growth had begun to plummet even before the pandemic. The 2020 census showed that from 2010 to 2020, the U.S. registered the second-lowest decade growth in its history—a consequence, in large part, of the aging of its population, which led to more deaths and fewer births. Nonetheless, the new data shows that pandemic-related demographic forces have left an indelible mark on the nation.
The unprecedented near cessation of U.S. population growth is depicted in Figure 1, which charts annual growth rates in the 121-year period from 1900 to 2021. Over this time, the nation experienced wide variations in growth, resulting from wars, economic booms and busts, as well as changing fertility and immigration patterns.
