A metropolitan area is a large urban region that includes a central city and its surrounding suburbs and towns. These areas are characterized by high population density and a mix of residential, commercial, and industrial spaces. For example, the New York City metropolitan area encompasses not just the city itself but also nearby places like Jersey City and Long Island. Metropolitan areas often serve as economic and cultural hubs, offering various job opportunities, entertainment, and services. They are connected by transportation systems, such as subways and buses, making it easier for people to commute. Cities like Los Angeles and Chicago are also examples of vibrant metropolitan areas.
