Are large cities losing young families faster than population overall?
Core argument: The under-five population in large urban U.S. counties fell 6.1% between April 2020 and July 2022, while those counties' overall population declined just 0.9%.
Since the beginning of the pandemic, the cumulative decline of under-five populations in large urban counties is now more than 6% —nearly twice the rate of decline nationally. Large urban areas are losing families with young children substantially faster than they are losing population overall. While the under-five population in such counties fell 6.1% between April 2020 and July 2022, the overall population declined by just 0.9%. In some of the country’s very largest counties, including New York, Cook County, IL, and Los Angeles, the population of young children is more than 10% smaller than in April 2020. Out-migration of young families from large and small urban counties has been more severe in the Mid-Atlantic and West Coast, while the under-five population actually grew in urban counties in the Southeast last year.
