Between 800,000 and 1,100,000 individuals in the US reported volunteering internationally each year from 2004 to 2012. Young, White college graduates with higher incomes, those who were employed, and married people were the most frequent international volunteers, the majority of whom served with a religious organization.
Data for this report were gathered from the volunteer supplements to the Current Population Survey (CPS)— a monthly survey of approximately 60,000 households—from September 2004 through September 2012. The volunteer supplement includes questions about domestic and international service performed. Two items specifically assess the rate and frequency of international volunteer service. (See Appendix 1 for more detailed information about sampling, definitions, and analysis.)
