Gentrify, Gentrifying, Gentrified: The Study of Philadelphia County, PA

Abstract
Residential Vulnerability
This study examined the condition of gentrification
and its associated indicators within the neighborhoods
of Philadelphia County following the guidelines set
forth by Portland’s Bureau of Planning and
Sustainability. The main focus of this study was on
three key indicators of gentrification, which are
Residential Vulnerability, Demographic Change, and
Housing Market Conditions. The results from these
three indicators were then plugged into a
gentrification scale culminating in the neighborhood
typology map.

In order to calculate the residential vulnerability
for a census tract, each census tract is assessed on
four risk factors. The four risk factors associated with
residential vulnerability are population 25+ without a
bachelor’s degree, renter-occupied housing, non-white
population, and median family income. Through this
residential vulnerability evaluation, 159 out of the 357
Philadelphia County residential census tracts qualify
for having a population vulnerable to displacement.

In order to calculate the demographic change for a
census tract, each census tract is assessed on four key
issues. The four issues associated with demographic
change are owner-occupied homes, white population,
population 25+ with a bachelor’s degree, and median
household income. Through this evaluation of
demographic change, 147 out of the 357 Philadelphia
County residential census tracts qualify for having
experienced demographic change.

Non-residential Census Tracts: all census tracts
not having a hundred residents or fifty homes in any of
the three decades (1990, 2000, or 2009) were removed
from the study
Data: obtained from the NCDB (1990, 2000, and
2010) and the ACS (2005-2009). All NCDB data was
normalized to the 2000 census tracts, and the ACS data
used the 2000 census tract boundaries as well.

In order to calculate the housing market condition
for a census tract, each census tract was first
designated as having either a low/moderate housing
value in 2010 or a high housing value. Through further
analysis, a census tract could then be labeled as being
part of the three housing market conditions: adjacent,
accelerating, or accelerated. Through this evaluation
of housing market conditions, there were a total of
126 Philadelphia County residential census tracts that
qualified for one of the three categories. There were
93 census tracts in the adjacent category, 10 in the
accelerating, and 23 in the appreciated.

In the neighborhood typology map, census tracts
can qualify for these six categories by:
Susceptible- adjacent housing condition, vulnerable
population, and no demographic change
Early: Type 1- accelerating housing condition,
vulnerable population, and no demographic change
Early: Type 2- adjacent housing condition, vulnerable
population, and experienced demographic change
Dynamic- accelerating housing condition, vulnerable
population, and experience demographic change Lateappreciated housing condition, vulnerable population,
and experienced demographic change
Continued Loss- appreciated housing condition, does
not qualify for vulnerable populations, and
experienced demographic change
