This essay examines ethnicity, nuptuality, and fertility in four centr
al Wisconsin counties which typi ed newly opened areas in the North Ce
ntral Region during the late nineteenth century. Frontier settlement w
as largely a family affair involving far more immigrants than native-b
orn migrants. Central Wisconsin settlers had higher child-woman ratios
than their national counterparts because they were more likely to be
married, and their children were more apt to survive infancy. Interrel
ated factors involving marriage patterns, religious beliefs, residence
, and husband's occupation were responsible for the fertility differen
tials among the ethnic groups within the region.
