This is BEA’s first official release of GDP by county statistics for 2001–2018 for all counties in the United States. The GDP by county statistics incorporate new and additional source data and methodology improvements to the December 2018 prototype GDP by county statistics. This release also expands the industry detail. The new GDP by county statistics along with BEA’s county estimates of personal income offer a more complete picture of local area economic conditions.
The release of GDP by county statistics replaces the release of GDP by metropolitan area statistics, previously occurring each September. GDP by metropolitan area statistics will now be made available with the release of GDP by county statistics, as shown in table 2.
Additional information on the GDP by county statistics, including a brief overview of the estimating methodology and data sources, is available here. Additional in-depth information on the methodology will be available in the February 2020 issue of the Survey of Current Business.
