The original purpose of the project (of which this book is an outgrowth) was to investigate the processes of value assimilation and behavioral change; the book has come to describe the economic absorption and cultural integration of Mexican Americans and Negroes into a predominantly Anglo society. The host society consisted of Anglos; they more frequently referred to themselves as Caucasians or whites, but since Mexican Americans were included in the study, it was decided at a very early point that it was best to use the designation Anglos. Focusing on the adjustment problems of inmigrant Mexican Americans and Negroes in a Northern industrial community around 1960, the authors define the basic problem as one of discerning which factors facilitated or impeded the assimilation of new values and the modification of behavior among inmigrants who had left their predominantly rural places of origin, mainly Mississippi and Texas, and now dwelt in the community of Racine, Wisconsin. Chapters in the book are devoted to the relationship of social antecedents to economic absorption and to present income and occupation; generational and intergenerational mobility; external and internal measures of absorption and integration; children and child-rearing practices; world view; associates and association; perceptions of community welfare organizations and agencies; and, implications of the study for community action.
