What does a census represent?

A census serves as the official head count of the population, capturing important demographic information about the number of people living in a specified area. This comprehensive count provides essential data that helps governments and organizations plan public services, allocate resources, and make informed policy decisions. The census aims to enumerate every individual, ensuring that even smaller or marginalized communities are represented.

In contrast, the other options focus on specific aspects of society but do not encompass the broad scope of a census. For instance, a survey about healthcare usage targets healthcare-related data rather than a complete population count. Similarly, a census does not specifically assess economic status or measure land area per person; these aspects may be evaluated through different statistical methods or surveys, but they do not define what a census is.
