How Some Shrinking Cities Are Still Prospering
A study finds that some shrinking cities are prosperous areas with smaller, more-educated populations. But they also have greater levels of income inequality.
But a new study suggests that shrinking population and economic decline don’t always come hand-in-hand: A striking subset of cities with declining populations are in fact economically prosperous. The report by Maxwell Hartt, my former University of Toronto colleague who is now at Cardiff University, examines the economic performance of American cities with shrinking populations, looking at their performance on indices of income, unemployment, job growth, and economic inequality from 1980 to 2010.
The map below, from the study, charts all 886 shrinking cities. The Rustbelt has large numbers of them, along with the Sunbelt and the Northeast. Less than a fifth of shrinking cities are principal cities (cities that are the largest incorporated place in a core-based statistical area or meet a threshold both for population and working population). Eightypercent of them are suburbs or smaller communities.
In the next map, Hartt charts the location of prosperous shrinking cities. Overall, Hartt finds that more than a quarter of shrinking cities (27 percent) can be defined as prosperous, having economic indices—the four factors mentioned earlier—greater than their regional average. Just 4 percent of prosperous shrinking cities are principal cities; the vast majority are suburbs and smaller places. For example, the affluent suburb of Mountain Brook, Alabama, has faced population decrease while maintaining high income and talent levels.
The study found no connection between the prosperity of cities and either the size of their population or the severity of population loss. “Remarkably, the severity of shrinkage was found to have no effect on income,” Harrt writes. “The lack of relationship between severity, persistence, and income demonstrates the diversity and complexity of urban shrinkage processes.”
The researchers findthat the main thing that distinguishes prosperous shrinking cities from a solely shrinking city is a particular type of talent. The strongest factor is college grads: 97 percent of prosperous shrinking cities had a higher proportion of college-educated individuals than their regional average.
This reflects the ongoing march of what Bill Bishop long ago dubbed the “big sort.” It’s not just that places are losing or gaining people in general. They’re specifically losing less-educated people while gaining more-educated people, a sorting process often exacerbated by expensive housing. Population growth is a crude measure of prosperity: As long as a place attracts or retains specific talent, it can lose general population and still be prosperous.
As a result, prosperous shrinking cities are also more unequal. More prosperous cities, even when they are losing people, have both greater levels of education and greater levels of inequality.
Of course, population loss and economic decline do inherently affect each other. Population loss can result in decreased tax revenues from income tax or real estate. This reduced fiscal capacity may result in fewer or poorer social services, resulting in even more population loss, dubbed the “feedback cycle of shrinkage.” Cities can break the shrinkage cycle by “planning for less”—diminishing the supply of housing or municipal expenditures in order to match city infrastructure with its population without excess.
The fact of shrinking, or losing population, does not condemn cities to economic decline in and of itself. More than a third of America’s shrinking cities are still economically successful by acting as talent magnets. And like other winner cities, they too suffer from the same new urban crisisbrought on bytheir success.
