The first official economic growth statistics for all U.S. counties show which industries contributed to growth from region to region and in counties large, medium, and small across the nation.
These new Bureau of Economic Analysis statistics feature every county's gross domestic product – the value of goods and services produced within the county – and how much the inflation-adjusted GDP grew or decreased from the previous year. The statistics, for 2001 through 2018, also show industries' contributions to the change in each county's GDP.;
