Cities generally have complex systems for sanitation, utilities, land usage, housing, and transportation. The

concentration of development greatly facilitates interaction between people and businesses, benefiting both parties in the process. A big city or metropolis usually has associated suburbs and exurbs. Such cities are usually associated with

metropolitan areas and urban areas, creating numerous business commuters traveling to urban centers of

employment. Once a city expands far enough to reach another city, this region can be deemed a conurbation or

megalopolis.

• Housing: Housing in cities and where people choose to live can often lead to or be a product of problems inherent in the city. Gentrification of certain areas within cities can lead to the forcing out of lower income residents to makeway for more affluent city dwellers.

• Crime: Issues of concentrated poverty and segregated residential areas can contribute to pockets of high crime rate areas within cities. Areas of higher crime rates often suffer from plummeting property values.

community cohesion.
