Below is a list of core cities in the United States that have seen their populations rebound following several decades of decline. In some instances, such as Denver, Des Moines, San Francisco, and Seattle, the core city is now attained a new peak population. Of the cities on this list, only Denver has seen a significant increase in its geographic area in order to build Denver International Airport. Otherwise, this list is meant to show cities where the core occupies essentially the same geographic area as it did during the prior peak and the low point. Cities such as Indianapolis, Nashville, Columbus, and Louisville were intentionally not included because a significant portion of their population growth has been fueled by annexations and/or consolidation with the surrounding county.
Two other cities, Cincinnati and Pittsburgh appear to have leveled off at their low points. Hopefully, the data below can provide a glimmer of hope for other core cities such as Buffalo, Cleveland, Detroit, and St. Louis, which are still suffering population loss.
