The data for this website were collected through two supplements to the Current Population Survey (CPS); the Volunteer Supplement and the Civic Supplement. The CPS is a monthly survey of about 60,000 households, (approximately 100,000 adults) conducted by the U.S. Census Bureau for the Bureau of Labor Statistics. The selected supplements collect data on the volunteering, voting, and civic activities of adults age 16 and older for volunteering and 18 and older for the civic supplement. Volunteers are considered individuals who performed unpaid volunteer activities through or for an organization at any point during the 12-month period, from September 1 of the prior year through the survey week in September of the survey year.
