There is a strong tradition in the social sciences that links the migr
ation of southern blacks to northern cities with changes in family str
ucture in the North. This article examines that assumption by comparin
g the living arrangements of children and women for migrants and nonmi
grants in northern central cities. Data from the newly available Integ
rated Public Use Microdata Series, for the period 1940 through 1990, a
re used for this purpose. The findings show that northern urbanites wi
th ''southern origins'' actually exhibited move traditional family pat
terns - more children living with two parents, more ever-married women
living with their spouses, and fewer never-married mothers. It is con
cluded that the evidence yields no support for the longstanding assump
tion that southern migrants contributed disproportionately to changes
in the African American family in northern cities during this century.
