Demographic Statistics
Demographic statistics (pronunciation: /dɪˌmɒɡræfɪk stəˈtɪstɪks/) are a form of quantitative data that represent the characteristics of a population. These characteristics can include age, sex, income level, race, employment, location, and any other population-specific factors.
Etymology
The term "demographic" originates from the Greek words "demos" meaning people and "grapho" meaning to write. "Statistics" is derived from the Latin word "statisticum collegium" which means council of state.

Uses of Demographic Statistics
Demographic statistics are used in a variety of fields, including marketing, politics, and economics. They are used to understand the characteristics of a population and to predict trends.

Additionally, demographic statistics can only provide a snapshot of a population at a certain point in time and may not accurately represent changes over time.
