What is a key advantage of census data?

• A. They provide complete data about social and economic characteristics
• B. They are biased toward a specific subgroup
• C. They lack any information about population
• D. They are limited to health records

Answer: (A)

One major advantage is that census data aim to count every person in the population, providing complete data about social and economic characteristics for the defined population. Because it tries to cover everyone, it reduces sampling error and allows detailed analysis across subgroups and geographic areas, which is invaluable for planning, policy, and resource allocation. The other statements describe drawbacks or narrower data sources that don’t reflect the broad, universal scope of census information.
