Demographics are the most recent statistical characteristics of a population. These types of data are used widely in sociology (and especially in the sub-field of demography), public policy, and marketing. [ Commonly examined demographics include gender, race, age, disabilities, mobility, home ownership, employment status, and even location. Demographic trends describe the historical changes in demographics in a population over time. Both distributions and trends of values within a demographic variable are of interest. Demographics are about the population of a region and the culture of the people there.
