In a community-defined, epidemiologic sample in East Baltimore, we exa
mined grandmothers' rates of co-residence and their;involvement in fou
r parenting activities. Co-residence rates exceeded the national avera
ge. Six types of family households with grandmothers were identified,
and their frequency varied by race. Neither grandmother age nor employ
ment was associated with grandmothers' parenting involvement, although
family structure was. Grandmothers who were the sole parent (21%) or
co-parent with a grandfather (6.5%) were most involved in child care a
nd had the fewest number of helpers. Grandmothers living with single m
others (41%) were the next most involved, while grandmothers in mother
/father households (9%) were least involved.
