To determine America’s fastest shrinking cities, 24/7 Wall St. reviewed data from the U.S. Census Bureau’s Population and Housing Estimates Program. Metropolitan statistical areas were ranked based on the percentage change in total population from July 1, 2010, to July 1, 2019. Data on population change due to natural change — the net difference between births and deaths — and due to net migration also came from the Census Bureau. Supplemental data on median household income came from the Census Bureau’s 2019 American Community Survey. Data on annual unemployment rate and employment changes came from the Bureau of Labor Statistics. These data are pre the COVID-19 pandemic.
