The correct answer is: d) All of the above
A census is a count of a population. It is a statistical survey that collects data about the population, such as age, sex, race, ethnicity, housing, and employment. The census is used to determine the number of people in a country or region, and to collect information about the characteristics of the population. This information is used to plan for the future, such as by determining the need for schools, hospitals, and other public services.
Demographics are the characteristics of a population, such as age, sex, race, ethnicity, and religion. Social indicators are measures of the well-being of a population, such as poverty, crime, and education. Economic activities are the things that people do to earn a living, such as working, running a business, or investing.
The census collects data on all of these aspects of the population. This data is used to track changes in the population over time, to identify areas with special needs, and to make decisions about how to allocate resources.
