What sociologist argued that the nuclear family was dominant in Western Europe due to life expectancy?

The correct response highlights the sociologist who is often associated with the argument that life expectancy has a significant impact on the structure of family in Western Europe, specifically regarding the prominence of the nuclear family. This perspective emphasizes that as life expectancy increased, there was a tendency for families to become more nuclear in structure, enabling them to establish a more independent and self-reliant household.

This viewpoint interlinks with broader sociological themes concerning family dynamics and the changes in social norms over time. Understanding how demographics like life expectancy can shift family structures aids in comprehending the evolution of family forms in different cultural contexts.

The other names mentioned are not primarily recognized for this specific argument on life expectancy influencing the nuclear family structure. Their works may focus on various aspects of family and social structures, but they do not make the same connection in relation to life expectancy and the dominance of the nuclear family in Western Europe.
