Definition - What does Demographic Data mean?
Techopedia explains Demographic Data
Demographic data is also used by marketers and business entities for targeted advertising and product distribution. For example, in areas with a large population density of Latinos, fast food restaurants often offer Mexican-themed foods as opposed to Mediterranean ones. Branches of famous American fast food companies in foreign countries often tailor their menu according to the local taste. All of these are due to demographic research using demographic data.
