13.1 Who Are the Elderly? Aging in Society

Older adults are divided into three age groups: young-old, middle-old, and old-old. Each group has unique characteristics and needs, from maintaining an active lifestyle to requiring significant assistance with daily activities. Understanding these differences is crucial for providing appropriate care and support.

Increased life expectancy has led to a growing population of older adults, impacting healthcare, social systems, and society as a whole. This demographic shift presents challenges, such as increased healthcare costs, but also opportunities for older adults to contribute their knowledge and experience to society.

  • Growing population of older adults, leading to a shift in demographics
  • Increased demand for healthcare and long-term care services to support the aging population
  • Strain on social security and pension systems, as more people rely on these benefits for longer periods
  • Potential for intergenerational conflicts over resources, such as funding for education vs. elder care
