How has the definition of "family" evolved over the last century?

The concept of family has undergone significant transformations throughout the 20th and 21st centuries. Traditional family structures, often characterized by a nuclear model of two parents and their children, have expanded to include a wide variety of forms, such as single-parent families, blended families, and families led by same-sex couples. Additionally, cultural shifts have influenced family roles and responsibilities, altering perceptions and expectations. Investigating these changes offers valuable insights into how societal norms, legal frameworks, and economic pressures have shaped the diverse understanding of family today.
