A metropolitan area is a region that includes a large city and its surrounding suburbs and towns. It is characterized by a high population density and a strong economic connection among the areas. These regions often share infrastructure, such as transportation systems and public services, making them interconnected. Metropolitan areas can vary in size and can include multiple cities or towns that are closely linked. For example, the New York City metropolitan area encompasses not only New York City but also parts of New Jersey and Connecticut. This interconnectedness allows for a diverse range of cultural, social, and economic activities.
