The real gross domestic product (GDP) of private industries has steadily increased nationwide from 2018-2022, with an average percentage increase of 2% each year, or 9% total, despite a drop from 2019-2020 due to the pandemic. However, the same cannot be said across all private industries; of the 14 broad industries captured by U.S. Bureau of Economic Analysis (BEA) data,[1] eight have grown while six decreased over the five-year period from 2018-2022.

From 2002-2021 (the last 20 years for which data is available), the total U.S. real gross domestic product (GDP adjusted for inflation, or Real GDP) increased by approximately 45%, from $13.5 trillion to $19.6 trillion in chained 2012 dollars. On a per capita basis, county-level real GDP increased by an average of 36% over the past 20 years, with a range of growth from -77% (Brooks County, Texas) to 3,950% (Culberson County, Texas).

This edition of Useful Stats takes a high-level look at the United States’ change in Real Gross Domestic Product (RGDP, which is GDP adjusted for inflation) on a per capita basis for each of its counties, boroughs, parishes, etc. (hereon referred to as “counties”). Looking at RGDP per capita allows for an inflation adjusted, population standardized metric for comparing counties over time.

This week’s edition of Useful Stats examines the contributions to county-level GDP in 2020 by industry group. Specifically, this analysis identifies the industries that contributed the most to the economic output of each county in 2020, as well as examining the annual percent changes in industry contribution to county GDP over the previous year. Most industries experienced declines brought on by the economic recession of 2020, although some experienced growth.

Although changes in gross domestic product (GDP) give us an idea of how economies are changing, this measure fails to tell the full story. This edition of Useful Stats examines county-level GDP-per-capita, the measure of economic output for each resident in an area. What we see is strongly skewed data with high 2018 GDP-per-capita levels and high 10-year growth rates concentrated primarily in low population-high output counties.

Building on SSTI’s recent analysis of county-level GDP by industry, this edition moves beyond a single year and examines the changes in real — adjusted for inflation — county GDP and the changes in industry-specific contributions to county GDP for the 10-year period from 2009 to 2018. As shown in the interactive map below, the total 10-year growth rate for counties averaged approximately 21 percent.
