More Sensationalism About Gentrification

Governing's recent study of gentrification systematically exaggerates gentrification in a variety of ways.

The ordinarily responsible Governing magazine is running a study of gentrification on its website; the study purports to show high levels of gentrification in some cities. For example, the study claims that 29 percent of New York's poor census tracts have gentrified. 

But the methodology of this study is a bit suspect. It measures gentrification not by income or poverty, but by two criteria: (1) rising home values and (2) the growth of college graduates. The first method means that if people are growing poorer due to high housing costs, their neighborhood must be growing richer. It seems to me, however, that a neighborhood is not richer just because it is experiencing a housing bubble, or because it did not suffer a housing bust.  

To be sure, there is some relationship between housing values and gentrification: other things being equal, higher incomes lead to higher demand lead to higher home prices. But other things are never equal: for example, in a small census tract with only a few houses, one or two condo buildings can skew average values upward.

The second element is also a less than ideal measure. In 1970, only 10 percent of Americans over 25 were college graduates—a percentage that nearly tripled over the following 40 years. Between 2000 and 2010, the percentage of college graduates increased in every single state. As college educations have become more common, I suspect that even the poorest places probably have more college graduates than they did a few decades ago. So if more college graduates=gentrification, one will naturally find gentrification everywhere.  (To be fair, Governing used growth in college graduates rather than the raw number of graduates as a measure of gentrification; however, even less than explosive growth qualified census tracts as gentrifying.  For example, one Kansas City census tract was classified as "gentrified" although its percentage of college graduates increased from 6 percent all the way up to 11 percent- a level only slightly higher than that of the city's poorest areas.  The study described another neighborhood as "gentrified" because the percentage of graduates tripled- overlooking the fact that the percentage increased from 3 percent to a still-dismal 9 percent).  Similarly, in Atlanta the dirt-poor Vine City neighborhood (where the median household income was under $20,000) was counted as "gentrified".

If gentrification means "more rich people" or "fewer poor people," it seems to me that a more appropriate measure of gentrification should address income: did incomes rise or fall? Did poverty rise or fall? And even if poverty fell, is a neighborhood's poverty rate anywhere close to suburban levels, or did an place with super-high poverty rates merely become a place with high poverty rates?

In addition, it seems to me that any study of gentrification should study degentrification as well: that is, to what extent were rising incomes in some urban neighborhoods balanced out by falling incomes and rising poverty in other neighborhoods? I suspect that a study considering this element would yield radically different results.*

*In particular the City Observatory website contains a wealth of data (pun intended) on neighborhood poverty.
