Shrinking cities in the United States

The following municipalities in the United States have lost at least 20% of their population, from a peak of over 100,000, since 1950. In all but a few cases, the surrounding metropolitan areas and urban areas (including the shrinking metropolitan areas) have increased in population. In recent decades, most of the cities in the Northeast have begun growing again.

A patchwork of cities across the northern United States, because of their vibrant industrial economies, were referred to collectively as "the Foundry of the Nation". These are also referred to as the Manufacturing Belt or the Factory Belt. This includes most of the cities of the Midwest out to the Mississippi River, and many of those in the New England and Mid-Atlantic states, particularly those away from the Eastern Seaboard. After World War II, the cities in the area among the nation's 100 largest in the middle-20th century had population that had fallen most by the century's end.

At the center lies an area stretching from northern Indiana and southern Michigan in the west to Upstate New York in the east, where local tax revenues still rely more heavily on manufacturing than on any other sector (by far the largest contiguous area of the U.S. where this is the case).
