Which statement best describes sustainability concerns regarding health expenditure?

• A. Decreasing costs due to aging population
• B. Increasing costs due to aging population and chronic disease
• C. Health expenditure is stable
• D. Private insurance covers all costs

Answer: (B)

Sustainability of health expenditure is driven by how demand and costs grow as the population ages and chronic disease becomes more common. As people live longer, they typically require more health services—hospital care, long-term support, medications, and ongoing management of multiple conditions. Chronic diseases, which require ongoing monitoring, treatment, and often expensive therapies, add costs year after year. Taken together, these factors push total health spending upward, making rising costs the central sustainability challenge.

Decreasing costs due to an aging population doesn’t fit reality, since aging tends to increase, not reduce, demand for care. Assuming health expenditure is stable ignores clear demographic and disease trends that drive growth. The idea that private insurance covers all costs overlooks system-wide financing realities and gaps in coverage, which are precisely what sustainability concerns address.
