Aging Population Increases Health Demands

Steps:

• Identify the demographic change: Rise in retired people means more elderly individuals.
• Link to needs: Elderly often require more healthcare due to age-related issues.
• Connect to government spending: Public health services directly support this group.
• Evaluate options: Match which expenditure aligns with elderly demands.

Why B is correct:

• Health services expenditure rises with aging populations, as defined by public health economics where retiree healthcare costs increase due to chronic conditions and longevity.

Why the others are wrong:

• A. Defence: Relates to national security, unaffected by retiree numbers.
• C. Training grants: Targets workforce development, less relevant for retirees.
• D. Street lighting: Involves infrastructure maintenance, not tied to population age.

Final answer: B
