Children live in a variety of family arrangements, some of which are complex, as a consequence of the marriage, divorce, and remarriage patterns of their parents. In addition, one-third of children today are born out-of-wedlock and may grow-up in singleparent families or spend significant portions of their lives with other relatives or stepparents. This report examines the diversity of childrenfs living arrangements in American households. The data are from the household relationship module of the Survey of Income and Program Participation (SIPP), collected in the fall of 1996, and update a 1994 study that presented estimates from the 1991 SIPP panel of the number of children growing up in various family situations.
