A more thorough explanation:

URBAN

Urban, adjective. Of or relating to a city or town; not rural.

The term urban refers to anything that is related to a city or town. It is the opposite of rural, which means countryside or farmland.

• Living in an urban area means having access to public transportation, shopping centers, and entertainment venues.
• The urban landscape is characterized by tall buildings, busy streets, and a lot of people.
• Many people prefer the rural lifestyle because it offers a quieter and more peaceful environment than the urban lifestyle.

The first two examples illustrate the definition of urban by describing the characteristics of a city or town. The third example contrasts urban with rural to emphasize the difference between living in a city versus living in the countryside.
