According to the U.S. Census Bureau, nearly 30,000 ditched major cities last year. The bureau accounted for people aged 25 to 39 years old. A report from Axios says the moves are mainly due to rising house costs. It adds that young people are mostly re-locating to suburbs outside of high-priced cities. Major urban areas where young people are fleeing include Chicago and Washington, D.C. 'The Wall Street Journal' says that some affordable cities are seeing a rise in millennials. These areas include Austin, Texas, and Columbus, Ohio. According to SmartAsset, a 2018 report shows that NYC is losing in popularity to Seattle and Denver.
