Which characteristic is used to describe an urban settlement?

Urban settlements are characterized by their typically large size. These areas are usually densely populated, featuring a multitude of residential, commercial, and industrial developments. The large population often results in a diverse range of facilities and services such as schools, hospitals, and transportation networks, which distinguish urban areas from rural settlements.

In contrast, characteristics associated with smaller or rural areas include lower population density, agricultural land use, and more open space. Urban settlements thrive on the concentration of resources, economic activities, and infrastructure, marking a significant departure from the features typical of small, rural, or isolated communities. Therefore, the emphasis on size, as represented in the correct answer, is a fundamental attribute of urban environments.
