The correct answer is: d) All of the above.
A census is a count of a population. The primary objective of a census is to collect data on the population, including demographics, socio-economic indicators, and housing.
Demographics are the characteristics of a population, such as age, sex, race, ethnicity, and marital status. Socio-economic indicators are measures of the economic and social well-being of a population, such as income, education, and employment. Housing data includes information on the type of housing, the number of rooms, and the value of the property.
Census data is used to make decisions about a wide range of issues, such as how many seats each state should have in the House of Representatives, how to allocate federal funds, and where to build new schools and hospitals. It is also used by businesses to make decisions about where to locate their facilities and what products and services to offer.
The United States Census Bureau conducts a census every ten years. The next census will be held in 2020.
