The census was taken during the COVID-19 pandemic, which affected its administration. The census recorded a resident population of 331,449,281 in the 50 states and the national capital of Washington, D.C., reflecting an increase of 7.4 percent, or 22,703,743, over that of 2010.[3] The growth rate was the second-lowest ever recorded, and the net increase was the sixth highest in history. This was the first census where the 10 most-populous states each surpassed 10 million residents, and the first census where the 10 most-populous cities each surpassed 1 million residents.
