I investigate the factors that fostered the rise in separate living quarter
s for older nonmarried women since mid-century by examining the impact of O
ld Age Assistance on living arrangements in 1940 and 1950. I find that Old
Age Assistance substantially increased demand for separate living quarters,
but that demand depended upon the rules of the program, in particular whet
her children were held legally responsible for the care of their aged paren
ts. I argue that more than half of the decline in the fraction of older non
married women living with kin from 1950 to 1990 can be attributed to rising
Social Security benefits and expanded eligiblity and to the fact that Soci
al Security benefits were given with no strings attached. (C) 1999 Elsevier
