Which is a main factor that accounts for changes in American family structure?

One main factor that accounts for changes in American family structure is shifting societal attitudes and values. The concept of family has evolved over time, influenced by various factors such as women's emancipation movements, increased acceptance of non-traditional family forms, changing gender roles, and societal shifts towards individualism and personal fulfillment.
