Special Report

America's Most Obese Counties

Methodology

To determine America’s most obese counties, 24/7 Tempo reviewed adult obesity rates from the Robert Wood Johnson Foundation and the University of Wisconsin Population Health Institute joint program’s 2021 County Health Rankings & Roadmaps report. 

The adult obesity rate is defined as the share of adults 20 years and older who report a body mass index of 30 kg/m2 or higher. While the CHR report is from 2021, obesity rate figures published in the report are from 2017.

Of the 3,220 counties or county equivalents, 3,142 had boundaries that fell within one of the 50 states or the District of Columbia.

Counties with a 2019 five-year population estimate from the U.S. Census Bureau of less than 1,000 were excluded.

The remaining 3,106 places were ranked based on the adult obesity rate. Additional information on the share of adults who report no leisure-time physical activity, the share of adults diagnosed with diabetes, and the share of adults who report fair or poor health are also from the 2021 CHR.
