Review Questions
How did life expectancy changes during the post-World War II era affect family dynamics in American society?
Following World War II, life expectancy increased significantly due to advancements in healthcare and living standards. This rise allowed for longer intergenerational relationships, as grandparents lived longer and were more likely to be involved in family life. The changing dynamics often led to more multi-generational households, affecting social structures and family responsibilities.

The baby boom had a profound effect on life expectancy statistics as it not only increased the population but also shifted the demographic profile of society. As this large cohort aged, their longevity contributed to overall life expectancy rates. Additionally, their presence influenced healthcare policies and social services designed to cater to an aging population.
