Urbanization also has its benefits. As cities grow, their structure becomes more dense and rigid. When distances between jobs, housing, and services become shorter, they become more accessible. In addition, the various forms of public transportation help to make movement in cities more frictionless. For example, the subways or metros of large cities take care of a large chunk of their commuter traffic.

Cities also provide a large variety of services and recreational activities. Many modern cities offer specialized areas, such as parks, for recreational use. The shopping centers of large cities provide many necessary services. Educational establishments, such as different universities and institutes, attract people from rural areas and smaller cities into metropolises. All in all, the services provided by large cities are more comprehensive than those of the surrounding rural areas. 

Cities are also the centers of business. Large cities have concentrated workforces of highly educated people, which provide new thoughts and innovations for commercial use.
