Review Questions

• How does increased life expectancy affect the demographics of a population?
  • Increased life expectancy leads to an aging population, where a larger percentage of individuals are older adults. This shift impacts various aspects of society, including the workforce, healthcare demands, and support systems for the elderly. With more people living longer lives, there is a greater need for policies that address the needs of older adults and ensure their well-being.
• Discuss the relationship between increased life expectancy and healthcare access in different socioeconomic groups.
  • Increased life expectancy is often linked to better healthcare access; however, disparities exist across socioeconomic groups. Wealthier populations typically have greater access to quality healthcare services, leading to longer life expectancies. In contrast, marginalized communities may face barriers such as poverty or lack of insurance, resulting in lower life expectancies. Addressing these inequalities is essential for improving overall population health.
• Evaluate the implications of increased life expectancy on family dynamics and intergenerational relationships.
  • Increased life expectancy has profound implications for family dynamics as it can alter traditional roles and responsibilities within families. Older adults may require care from younger family members for longer periods, changing the nature of relationships across generations. This shift can lead to increased caregiving responsibilities for middle-aged adults while fostering closer bonds as families navigate the challenges and opportunities presented by longer lifespans. Additionally, it raises questions about resource allocation and support systems needed to assist families in these evolving roles.
