An Urban Center The coastal region of the Northeast is a megalopolis, a type of region where cities and suburbs have grown so close together they form one big urban area. The Northeast is the most densely populated region of the United States. Population density is the average number of people per square mile. The population is denser in parts of New Jersey than in crowded countries like India and Japan. Today, manufacturing, finance, communications, and government employ millions of urban Northeasterners.
