Which term is used to describe a built-up area, such as a town or city?

The term used to describe a built-up area, such as a town or city, is "Urban Area." Urban areas are characterized by higher population density and vast human-made structures compared to rural areas. They typically feature infrastructure such as roads, bridges, buildings, and various public services designed to accommodate the larger population.

The concept of urban areas encompasses towns and cities and is integral to discussions about population density, economic activity, and social organization. Urban areas are often central to economic development, cultural exchanges, and administrative functions within a region. Understanding this term is crucial in geography, as it relates to patterns of human settlement and urbanization processes.

Other choices refer to different concepts. Rural areas denote regions that are not urbanized, typically with lower population density and more open space. Civic space generally refers to a specific area within a city designed for public activities and gatherings. Metropolitan regions are larger areas encompassing multiple cities and their suburbs, often defined by economic and social ties.
