Each year, approximately one million individuals reported volunteering abroad with marginal fluctuations year to year. This report gathered data from the volunteer supplement to the Current Populations Survey (CPS) from September 2004 through September 2010. Thus, this report provides a picture of demographic characteristics of international volunteer service among the U.S. population and the the rate and frequency during this time.
