American Cities That Are Running Out Of People

Population: 111,475

While most of the cities on this list are here as the result of a general decline in industry, Flint’s woes have come almost entirely from one sector – the auto industry. Flint became a boomtown at the turn of the century as it became a divisional headquarters to the major American auto manufacturers, including Chevrolet, Buick, and General Motors. Between 1910 and 1930, the population had more than quadrupled due to the success of the American car business. Since the American auto industry began its decline in the 1980?s, Flint has consistently lost at least 10% of its population each decade. Massive layoffs and plant closings have devastated the city, and unemployment rates remain well into the double digits.

American Cities ... The population of the United States has increased steadily by roughly 2.5 million people every year since World War II.

Throughout prosperity and hard times, Americans continue to have families. Many of the country’s regions have expanded to accommodate this population increase.

There are some cities, however, which have experienced such severe hardship and decline that their populations have actually decreased significantly.

24/7 Wall St. obtained its population data from the U.S. Census Bureau’s Population Division. Housing Vacancy came from the Census Bureau’s American Community Survey. This is a list of the seven American cities that have lost the most people in the past decade.

7. Rochester, N.... Population: 207,294

Population Percent Change 2000-2009: -5.55 percent

The City of Rochester was once a booming trade center, largely due to its location at the midpoint between Albany and Buffalo on the Erie Canal. At its peak, the city was the major flour processor in the country, and was home to several key corporations including Xerox and Eastman Kodak. Rochester declined as the usefulness of the canal went out with the advent of railroads and its flagship companies began to lose their relevancy in the larger global economy. Rochester has yet to produce an important replacement industry to drive up the population, and even the success in the 1990’s of Xerox has faded. Between 1950 and 2000, Rochester lost 34 percent of its population.

6. Pittsburgh, P... Population: 311,647

Known as the “Steel City,” Pittsburgh was once the forge for the American industrial engine from the late 1800?s through the late 1970?s. At its peak, the city was home to more than 1,000 factories, including the mills owned by Pittsburgh-based U.S. Steel, which by itself employed over 340,000 workers during World War II. As the American steel industry collapsed in the 19 80?s Pittsburgh suffered severe unemployment problems. In the past few decades, the city changed to a technology-based economy, but the population is still on the decline. Since 1950, Pittsburgh’s population has declined by more than 50 percent.

5. Dayton, Ohio Population: 153,843

For its size, Dayton, Ohio was once one of the most productive and creative cities in the U.S. It produced more patents per capita at the turn of the century than any other. The city was home to several former great Fortune 500 companies, including National Cash Register, Mead Paper and Phillips Manufacturing. Through the first half of the 20th century, Dayton had one of the healthiest manufacturing industries. It had more GM autoworkers than any city outside of Michigan during World War II. In the past 50 years, Mead has merged with West Virginia Paper and moved to Richmond, and GM has closed one plant after another in the city.

4. Buffalo, N.Y.... Population: 270,240

Another victim of the Erie Canal boom and bust, Buffalo was the 13th largest city in the country just before WW II. It is now the 70th. Like Rochester, the city was once a premier mill town due to its location to the canal. Massive electricity generation from Niagara Falls improved Buffalo’s industrial capacity, and the city referred to itself as the “City of Lights” for a time because of its power production. The collapse of the canal and improvements in the energy industry which made Niagara Falls less important led to the mass migration from the city which continues to this day. In the 1970?s alone, Buffalo lost more than 100,000 residents, roughly a third of its current population.

3. Cleveland, Oh... Population: 431,369

Cleveland, the largest city on our list, was once a thriving manufacturing center, as well as an important point of trade because of its connection to several key routes particularly Lake Erie. The city was once home to a sizable auto industry. Most of the largest companies which were once based in Cleveland no longer exist. These include Peerless, People’s and Winton. Cleveland also served as headquarters for John D. Rockefeller’s Standard Oil Company, as well as a key import location for coal and iron shipped from the South and Midwest. The decline of industrial American has hit the city particularly hard, and poverty, a default on municipal debt in the 70?s, and pollution have earned the city the nickname “the mistake on the lake.” In 1948, the city had over 910,000 people; it now has less than half of that.

New Orleans is unique in that its presence on this list is not due to industrial decline, but from natural disaster. Hurricane Katrina flooded 80 percent of the city, caused by some estimates more than $80 billion in damage, and displaced tens of thousands of residents. The period of widespread homelessness, severe crime, and slow recovery has left the city as a shadow of its former self. While people are trickling back into the city, many will likely never return, and the city has lost more than a quarter of its population in just ten years.
