Between 800,000 and 1,100,000 individuals reported volunteering internationally each year from 2004 to 2010. Young, white, college graduates with higherincomes, employed, and married people were the most frequent candidates for volunteer service abroad. The majority of international volunteers served with a religious organization.
Data for this report were gathered from the September 2004 through September 2010 volunteer supplements to the Current Population Survey (CPS)—a monthly survey of approximately 60,000 households. The volunteer supplement includes questions about service performed domestically and abroad. Two items specifically assess the rate and frequency of international volunteer service. More detailed information about sampling, definitions, and analysis can be found under Methodological Notes at the end of this report.
