The problem of discrimination against families within the context of changing sex roles and the growing diversity of family structure is discussed in this paper. It begins with an analysis of underlying social trends, then focuses on sex discrimination and discrimination against different family types and concludes with an interpretation of emerging family values. In Section One: Trends in Sex Roles and Family Life, discussion centers upon women's rising labor force participation, changes in household form, and measures of discrimination. Section Two: Sex Role Discrimination and Family Life focuses on the issues of economic support functions, child care and nurturing, and the impact of sex discrimination on both husband-wife and female-headed families. In Section Three: Discrimination by Household Type and Family Form, issues for single-parent families, living arrangements of unrelated individuals, as well as extended families, family size, and family composition are discussed. In conclusion, Section Four: Possible Future Developments briefly explores the topics of greater sex role flexibility, broader definitions of family values, diversity in life patterns, and policies to promote equity among and choice of alternate family forms.
