Methodology: 

To determine the fastest shrinking U.S. cities, 24/7 Wall St. reviewed population change between July 2010 and July 2018 (the latest available data) in every U.S. metro area with data from the U.S. Census Bureau’s Population Estimates Program. Figures on each component of population growth — births, deaths, and international and domestic migration — also came from this report and are from April 2010 to July 2018. Employment change between 2010 and 2018 came from the Bureau of Labor Statistics’ Quarterly Census of Employment and Wages. 2018 unemployment rates came from the Bureau of Labor Statistics’ Local Area Unemployment Statistics. Median household income, poverty rate, SNAP recipiency rate, and demographic data are five-year averages from the U.S. Census Bureau’s 2017 American Community Survey.
