The demographic and socioeconomic characteristics of single parent fam
ilies have changed dramatically during the past three decades. The inc
rease in single parent families, which was particularly great during t
he late 1960s and 1970s, slowed in the 1980s. Whereas the increase in
divorce fueled the growth in one-parent families in the 1960s and 1970
s, delayed marriage and childbearing outside marriage contributed far
more to growth in the mother-child families during the 1980s than did
marital disruption. During the 1980s, father-child families increased
faster than mother-child families. By 1990, almost one in five single
parent families was maintained by a father, although only 3 percent of
all children lived in this type of household. Single parenting on the
part of unmarried mothers is much higher within the black than white
community and racial differences were as large or larger at the beginn
ing of the 1990s as a generation earlier. Whereas two-thirds of white
children currently live with both biological parents, only one-quarter
of black children do so. Single parent families remain disadvantaged
relative to two-parent families in economic status, health, and housin
g conditions and children living with a never-married mother are the m
ost economically disadvantaged group of children in single parent fami
lies. Projections are that one-half of children born in the 1980s will
spend some time living in a one-parent situation. The picture of life
with a single parent is being enhanced by new data collection and ana
lyses of extended family living arrangements and the role of cohabitat
ion. Among children born in the 1980s, it is estimated that as much as
one-third of the time they will spend in a mother-child family will b
e in their grandparents home or living in a household which includes t
heir mother's cohabitating partner.
