Increasing numbers of poor Mexican immigrant families are settling in the rural southeastern United States. Most of these families are from isolated agrarian communities in Mexico and are headed by unskilled laborers or displaced farm workers with little education. Child welfare workers and other service providers in rural communities may be poorly prepared to address the needs of this population. This article provides an overview of the cultural, social, and family dynamics of first generation, working class Mexicans to promote cultural competency among helping professionals. An ecological perspective is used to examine the strengths that poor Mexicans bring from their culture of origin, stresses of the migratory experience and ongoing adaptation, shifts that may occur in family structure and functioning, disruptions in the family life cycle, the role of social supports in family adaptation, and effect of institutional discrimination on family well-being. Suggestions also are made for essential components of adequate in-service education. -Description from source
