Among volunteers with children under 18 years old, 45.8 percent of mothers and 40.6 percent of fathers volunteered mainly for an educational or youth service organization, such as a school or scouting group.

Volunteers without children under 18 were considerably more likely than parents to

volunteer for other types of organizations, such as hospitals or other health organizations and social or community service organizations.
