What Do Demographers Study?

A demographer studies the characteristics of human populations, such as size, growth, density, distribution and vital statistics. Vital statistics include statistics relating to important events in human life such as births, deaths and marriages.

Demographers collect and analyze quantitative data relating to human populations. Demographic studies can be done using entire societies or groups within a society based on criteria such as nationality, religion or gender. Demographic data can be interpreted into statistics used in fields such as housing, healthcare and business.

Many demographers specialize in the study of certain populations and relationships. Demographers may study specific areas, such as women in business or the effects of employees having a college education in a certain industry. Demographers can be employed by government and social service agencies to aid in planning. Businesses may also rely on demographic research for advertising and product development.

Demographers regularly study data related to population distribution including migrations. This data includes immigration and emigration statistics and trends. Demographers use the data that they collect and interpret to predict trends in areas such as population growth and distribution. Demographic data can be collected in a variety of ways including surveys and interviews. It can also be collected from sources such as government censuses and immigration records.
