In the United States, a small proportion of private donors gives to international charity. We explore the profile of these donors with a view to understanding who supports international causes relative to domestic causes only and, more generally, what shapes public concern for those in need in other countries. Using data from the 2001 survey on "Giving and Volunteering in the United States," we employ a series of probit regressions to compare the sociodemographic correlates of giving to international causes with 11 other domestic causes such as health, education, and the arts. We find that while income is not associated with the likelihood of international giving, postgraduate education, being foreign-born, and religiosity are large and significant predictors. We also explore the impact of various measures of social capital and civic engagement, and find that institutional trust and youth volunteering are strongly associated with international giving relative to the other causes.
