About the Data 

The Labor Force Participation Rate determines what percentage of the working age population is in the labor force. The Bureau of Labor Statistics (BLS) defines civilian labor force to include all persons in the civilian noninstitutional population, ages 16 and older, classified as either employed or unemployed. In order to be considered unemployed, an individual must have had no employment during the reference week, been available for work, and have made an effort to find employment for four weeks leading up to the reference week.

This data comes from the American Community Survey, a survey done yearly by the US Census Bureau among a sample of residents and was retrived from the Ruth Mott Foundation's Community Dashboard. Statistics are an estimate of persons by place of residence, not jobs or where a person works.
