Urban geography is the study of how people use space in cities and how things are arranged in relation to each other. A city is defined functionally by what it does, not just by its size or population. It serves as the center of business and culture for a surrounding region. Elements of cities include suburbs, which touch the central city or other suburbs, and exurbs, which are smaller residential and commercial units farther from the main city. Land in cities is used for residential, industrial, and commercial purposes, and cities tend to develop near water access, at transportation intersections, or in sheltered areas that provide defensive positions or fuel and food supplies.
