The city is usually considered as the core of a metropolitan area, while a suburb is on the periphery of a city's limits. The city is a large town that is highly populated.
City life is typically a very crowded and busy place. Usually, most of the critical offices and buildings are available in the city. If you are looking for a comfortable life and easy access to modern facilities, the city should be your first choice. In the city, you can find educational institutes, shops, banks, and other business institutes, as well as developed infrastructure facilities like electricity, water, and telecommunication, are available within the city.
A suburb is an outlying district of a city. This term is espeicially used for residential areas. In general, suburbs have a lower population density than the city. Since suburbs are within a commuting distance from cities, many people, especially families choose to live in suburbs. Suburbs are quieter and less crowded than cities. Most people believe that it's good to raise a family in the suburb due to friendly neighbors, simple lifestyle, spend time with family in a less polluted area.
I like to live in suburbs because of bigger houses, friendly neighborhood, children playing areas and less polluted environment.
