Which factors contribute to the growing demand for PAs?

• A. Aging population, chronic diseases, and emphasis on cost-effective, quality care
• B. Decreasing life expectancy
• C. Decreasing insured population
• D. Aging population and limited access to care

Answer: (D)

The main idea is that demand for PAs grows when more people need care and when access to care is limited. An aging population naturally requires more medical attention, particularly for chronic conditions and routine management. At the same time, limited access to care—due to physician shortages or uneven distribution—creates a gap that PAs are well positioned to fill. They can provide timely primary and preventive care, manage chronic diseases, and help reduce wait times and costs, especially in underserved areas.

While chronic diseases are a big part of why care is needed, the key driver here is the access gap. Decreasing life expectancy or a shrinking insured population would typically reduce demand or shift it in different directions, whereas an aging population paired with limited access directly increases the need for mid‑level providers like PAs.
