Using a unique data set, the author investigates gender segregation in volu
ntary organizations. Results indicate that (I) women are more likely than m
en to belong to gender-segregated groups and (2) women's groups primarily r
estrict members to contact with persons of the same age, education, and mar
ital and work status. The article ends with a discussion of how segregated
voluntary associations help perpetuate a social world that is substantially
ordered by gender.
