Its population increased by 7.7 percent from 2010, when the census recorded a population of roughly 8.2 million residents.
At the start of the coronavirus pandemic last year, many residents left New York for locales with less density and more affordable housing, but the out migration wasn't enough to dent the city's strong growth over the past decade.2. Los Angeles

Phoenix serves as both the state capital and the seat of Maricopa, which contains roughly 61 percent of the state's population.
