Final answer:
The exact percentage of people over 65 requiring institutional care is not provided, but the data indicates a significant portion of the elderly population may need such care due to challenges in family caregiving and the increasing aging population.
Step-by-step explanation:
The question asks about the percentage of people over 65 who require institutional care. While the provided information does not give a direct percentage, it informs us about the challenges faced by the elderly, particularly in securing needed support and healthcare. With approximately 20% of the U.S. population over 60 years old, a significant number of individuals may require medical care.
However, family caregiving is strained due to employment commitments of caregivers, leading to gaps in care. The elderly population growth, known as "the graying of America," indicates a larger number of seniors who might need institutional care, especially as their life expectancy increases. Given these factors, while an exact percentage is not provided, it is implied that a substantial portion of the elderly may need institutional care.
