Providing an overview of American families today is a difficult task because of diversity, not only in race and ethnicity, but also in social, geographical, and cultural backgrounds. These varied family dimensions can influence perceptions and reactions to age, family composition, family characteristics, gender roles, family interests, health issues, economic conditions, education, and religion. In addition, over time, families change in multifaceted ways.

In this article, the author discusses the changes and challenges that families face in a diverse culture.
