In a rural community people live far apart from their neighbors. People usually must drive to places they need to visit, because it is too far to walk.
Homes in suburban communities have one family living in them. Sometimes families live in apartments, but they are not tall buildings. Many people have yards in suburban areas.
Urban communities are large cities. There is not much open space or natural areas. People live close together in a small amount of space. Many people live in tall apartment buildings.
