The purposes of the study conducted in Saginaw County, Michigan, were to determine (1) changes experienced by Spanish-speaking migrants, especially moves into and out of the labor force; (2) future changes in the availability of Spanish-speaking migrants for agricultural labor; (3) the significance of migrants' settling permanently in Michigan; (4) the extent of change to non-farm labor; (5) how migrant families adjust to their new environment; and (6) how achievements are related to length of time in Michigan. The information obtained by interviewing sample families revealed that: (1) the rural residents of the area were recent arrivals while the more successful urban dwellers were more permanently attached to the area; (2) most of the migrant adults had little difficulty adjusting to their new environment even though their English was limited; (3) since they were unskilled workers, the parents held relatively low educational aspirations, but aspirations were as high as the national level for their children; and (4) once a Mexican American family had moved into a non-farm job there was little desire to return to agricultural work. The conclusion of the study was that the current supply of Spanish-speaking children, both urban and rural, will contribute little to farm labor needs in Michigan. (RH)
