Demographics

Demographics are the physical characteristics of a population. Commonly-used demographics include race, age, income, disabilities, mobility (in terms of travel time to work or number of vehicles available), educational attainment, home ownership, employment status and even location. Demography is widely used for various purposes and can encompass small, targeted populations or mass populations. Governments use demography for political observations, scientists use it for research purposes while businesses use it in targeting advertising messages.
