National Survey of Families and Households 1987-88 (N = 13,017) data w
ere used to generate population estimates of in- and out-of-household
caregiving for persons of all ages. More than 1 in 7 U.S. adults repor
ted caring for relatives or friends during the previous year, includin
g more than 1 in 5 women aged 35-64. About one third of this care was
provided to nonelderly persons. Multivariate analyses revealed that ge
nder, age, marital status education, ethnicity, education, and employm
ent status helped predict the likelihood of caregiving.
