There is a growing moving-away from cities, Frey said
"Census: Big cities in US aren't growing like they used to" - Associated Press. 5/23/2019.
Most of the nation’s largest cities last year grew by a fraction of the numbers they did earlier in the decade, according to population and housing unit estimates released Thursday by the U.S. Census Bureau.
The previous growth big cities had experienced in the first half of the decade was fueled by millennials who delayed home-buying in the suburbs after the recession and stuck it out in large cities, said William Frey, a senior fellow at The Brooking Institution’s Metropolitan Policy Program.
