What is Gross Domestic Product (GDP) by County?
GDP is a comprehensive measure of the economies of counties. Gross domestic product estimates the value of the goods and services produced in an area. It can be used to compare the size and growth of county economies across the state.

This dataset is not not adjusted for inflation and represents the value of the goods and services in dollars at the time of the estimate. If you are looking to evaluate the growth of county economies over time, use of the Real GDP which is adjusted for inflation would eliminate changes in GDP caused by increases or decreases in the value of the US dollar. More information about the BEA's GDP by County is available here: GDP by County, Metro and Other Areas.

The population and housing unit estimates are released on a flow basis throughout each year. Each new series of data (called vintages) incorporates the latest administrative record data, geographic boundaries, and methodology. Therefore, the entire time series of estimates beginning with the date of the most recent decennial census is revised annually, and estimates from different vintages of data may not be consistent across geography and characteristics detail.
When multiple vintages of data are available, the most recent vintage is the preferred data.

The vintage year (e.g., V2021) refers to the final year of the time series. The reference date for all estimates is July 1, unless otherwise specified.

Additional estimates files may also be accessed via the Census Bureau application programming interface (API).
