The study finds the census tracts southwest of 23rd and Union and in the area below Madison around Seattle University and First Hill qualify as “chronically” and “newly” poor…

But Capitol Hill, technically, has not gentrified

A new study finds that gentrification is much lower than popularly thought, both in Seattle and across the country. Gentrification in Capitol Hill, however, appears to be on the rise.

City Observatory, a Portland-based “website and think tank devoted to data-driven analysis of cities and the policies that shape them,” in September released the report comparing poverty numbers from the 1970 and 2010 Censuses to look for evidence of gentrification in the country’s 51 largest cities. The report tries to look at displacement of poor people from a neighborhood, rather than the arrival of rich residents.

It defines gentrification like this: if, between 1970 and 2010, a Census tract went from a poverty rate of 30% or more to 15% or less, then that tract was categorized as gentrified. The national average poverty rate is about 15%.

Using this definition, there was no gentrification in Seattle during the past 40 years. But the number of impoverished Seattleites nearly quadrupled, and the number of high poverty (30%+) tracts more than doubled.

Based on this measure, it appears Seattle doesn’t have a problem with rich people displacing poor people, but rather with concentrated poverty — the opposite of gentrification.

But while none of the Census tracts on Capitol Hill — which we are roughly defining as the area between 23rd Ave., Marion St., I-5, and Interlaken Park — met the report’s formal definition of gentrification, almost all of them have seen big drops in the number of poor people living there since 1970. Cal Anderson Park’s tract, for instance, saw poverty fall from 19% to 12%, and its overall population grew by about 20%. By contrast, poverty in the tract housing Volunteer Park only fell from 9% to 8%, while the overall number of people living there stayed about the same. But that stability is the exception: six out of eight of Capitol Hill’s Census tracts have seen poverty significantly decline since 1970, and none have seen it increase.

The upshot of all this is that while changes on Capitol Hill don’t meet the City Observatory’s technical definition of gentrification (using the arbitrary benchmarks of 15% and 30% poverty rates), they do display a trend toward a lower poverty rate.

And it’s not just the rate: The actual count of poor people has gone down in all but one tract. How do we know? CHS multiplied the 1970 population by the 1970 poverty rate and the 2010 population by the 2010 poverty rate; this gave us the (rough) absolute number of impoverished residents for each tract in 1970 and in 2010. We then compared the 1970 and 2010 numbers of impoverished residents for each tract, and lo and behold: in all but one of the Census tracts, the absolute number of poor people has fallen.

So while Seattle may be free of formal gentrification, City Observatory’s numbers confirm what is plain to many residents: the rich are pushing the poor out of one of Seattle’s proudest neighborhoods.
