A "commuter belt" refers to an area surrounding a city where people live and travel daily to work in the city. These regions typically have good transportation links, such as trains or buses, making it convenient for residents to commute. The commuter belt often includes smaller towns and suburbs that offer a quieter lifestyle compared to the bustling city center. In many countries, such as the United Kingdom and United States, commuter belts have grown as urban populations increase. This growth can lead to higher demand for housing and services in these areas, impacting local economies and infrastructure.
