Which variables are included in census data?

• A. Population size and the distribution of age, sex, race, and ethnicity
• B. Only income and employment
• C. Geographic coordinates only
• D. Education level only

Answer: (A)

Census data are designed to describe who lives in a community and how they are distributed across the population. The core variables include population size and the basic demographic characteristics that describe people: age, sex, race, and ethnicity. Knowing these helps planners size services, target health resources, and identify groups with greater needs.

Other options miss the broader, multi-variable scope of census data. Income and employment are important, but they’re typically gathered in other surveys rather than the decennial census. Geographic coordinates are useful for mapping, but they aren’t the primary variables the census collects. Education level is only one facet and doesn’t by itself represent census data.
