The document outlines 5 types of family diversity identified by Rhona and Robert Rapoport: 1) Organizational diversity refers to differences in family roles and structures such as joint or segregated wage earning. 2) Cultural diversity accounts for differences between ethnic and religious groups' family structures. 3) Social class diversity influences family structure and child-rearing based on income differences. 4) Life-stage diversity means family structure depends on people's stages in the life cycle such as with newlyweds or retired couples. 5) Generational diversity exists as attitudes change over time between older and younger generations regarding issues like divorce and homosexuality.
