Demographics

Demographics are the most recent statistical characteristics of a population. These types of data are used widely in sociology (and especially in the subfield of demography), public policy, and marketing. Commonly examined demographics include gender, race, age, disabilities, mobility, home ownership, employment status, and even location.
