Which core function involves collecting and analyzing health data to determine population health status?

• A. Policy Development
• B. Assessment
• C. Assurance
• D. Intervention

Answer: (B)

Assessing population health involves systematically gathering health data, analyzing it, and interpreting the results to understand the overall health status of a community. This process—collecting surveillance data, compiling health indicators, and examining trends and disparities—creates a clear picture of how healthy the population is and where problems or priorities lie. That focus on turning data into an understanding of health status is what makes this function the best fit.

Other functions serve different roles: policy development uses information to shape policies and guide governance, assurance ensures that necessary services and quality are in place, and intervention involves putting programs into action to improve health. But when the goal is to collect and analyze data to determine population health status, the activity described is assessment.
