We use data from the Voting and Registration Supplement of the Current Population Survey to explore the effects of family structure on turnout in the 2000 presidential election. Our results indicate that family structure, defined as marital status and the presence of children, has substantial consequences for turnout. Married adults are more likely to vote than are those who have never been married; in turn, previously married people are the lightest voters. Children have a smaller but still noteworthy effect on turnout. These results are only partially explained by social and demographic differences. (Contains 3 tables and 4 notes.)
