Many changes in marital status and living arrangements have occurred over the last few decades. Noteworthy have been the continuing trends toward postponement of first marriage and higher levels of divorce. These and other marital status changes, particularly in the family formation ages, have re-shaped the living arrangements of children and adults since the 1970's - fewer children now live with two parents and more adults live alone. This report is based on the March 1996 Current Population Survey and provides estimates for the resident population, excluding military in barracks and people in institutions.
