Utilizing 1970 census data on a 45-county area in the northern Upper Great Lakes Region, the following questions were addressed: (1) In what ways do recent migrants to this nonmetropolitan region differ from those "nonmigrants" who resided in the region in both 1965 and 1970? (2) To what extent do the recent migrants from metropolitan counties differ from migrants from other nonmetropolitan counties? (3) Does the origin of migrants influence the character of their location in 1970? The populations represented were 985,000 residents of the region in 1970 who were 5 years or older and had reported U.S. residence in 1965 and a sub-population of 322,000 white heads of households in 1970. Migrants and non-migrants were compared in terms of sex differences, location of residence (urban, rural, rural nonfarm, and group quarters), age differences, and selected characteristics of white household heads. Results indicated that: inmigrants were considerably younger than the non-migrant residents (due to a higher propensity to migrate among the young in general and due to substantial outmigration among the young of this region); the majority of inmigrants had metropolitan origins and urban destinations, although they were attracted disproportionately to rural nonfarm locations (especially the older migrants seeking retirement); a substantial proportion of the inmigrants were enumerated in group quarters in 1970, having changed residence to attend an academic institution.
