Which family structure became more common due to changing social trends?

The nuclear family structure, typically consisting of two parents and their children, has become more common in recent decades due to various social trends such as urbanization, economic changes, and shifting cultural values. This structure is often favored in modern societies as it aligns more closely with contemporary lifestyles that prioritize mobility, career changes, and individualism.

In contrast, while extended families, which include other relatives such as grandparents and aunts or uncles, may still exist, they have become less prevalent as people move away from their home towns for opportunities and establish more independent households. Multi-generational families, though visible and useful for cultural and economic reasons, are not the dominant trend in many societies compared to the nuclear family. Compound families, which consist of multiple families living together, are also less common in today's societal norms.

The increasing investment in child-centered upbringing and the pursuit of personal development and career paths have also led to the rise of the nuclear family, making it the predominant family structure in many urban settings.
