Regional Economic Information System REIS

The U.S. Bureau of Economic Analysis produces annual estimates of employment (jobs) and earnings by place of work each year and for all counties in the nation. These estimates are based on covered payroll employment (ES-202 aka CEW) and administrative records (such as IRS). As a result, the BEA estimates include farm and non-farm sole proprietors, thus capturing a significant segment of jobs; when comparing these estimates against other job numbers for your county, you will likely find that this number is higher.
