What sources of data are used by demographers? Be sure to explain the information that each source provides to the demographer.

Answer:

Demographers use censuses, which count the population and provide information such as age, household size, and location. They use vital statistics or civil records, such as birth and death registrations, to track changes in the population and calculate rates. They also use sample surveys to collect detailed information from a smaller group and generalize the results to the larger population. Migration records can show how many people move into or out of an area.
