Which data source is most useful for understanding the age distribution of a population when interpreting health data for a school district?

• A. Centers for Disease Control and Prevention
• B. County health department
• C. United States Census Bureau
• D. Michigan Department of Health and Human Services

Answer: (C)

Understanding how many children and young people live in a school district relies on reliable demographic data that breaks down the population by age for the district’s geography. The United States Census Bureau is the primary source for this kind of information, providing official counts and age distributions through the decennial census and the American Community Survey. This data lets you estimate how many students are in different age groups within the district, which is essential when interpreting health metrics—such as vaccination rates, access to school-based health programs, or prevalence of health conditions—in the context of the actual student population. Other sources primarily focus on health indicators for a given area and may not offer the detailed, up-to-date age structure by school-district boundaries, so the Census Bureau is the most useful starting point for understanding age distribution.
