About 64.5 million persons, or 28.8 percent of the civilian noninstitutional population age 16 and over, volunteered through or for organizations at least once from September 2003 to September 2004.
One-fourth of men and about one-third of women did volunteer work in the year ended in September 2004, about the same proportions as in the prior year. Women volunteered at a higher rate than men across age groups, education levels, and other major characteristics.
