Counties that Biden won in the 2020 presidential election accounted for 68 percent of U.S. job growth from 2016 to 2019. By flipping Maricopa County, Arizona, which had gone to the Republican candidate in the past three presidential elections, Biden was able to win 19 of the 20 counties that had the biggest increases in total jobs. Union County, North Carolina, (outside Charlotte), which ranked 20th, was the Trump county with the most employment growth. Among the counties ranked between 20 and 100 for employment growth, Biden won two-thirds of those counties. Florida and Texas together accounted for around one-fifth of total jobs gained across both Trump and Biden counties.
