Property tax -- Oregon, Gentrification -- Government policy, Gentrification -- Oregon -- Portland, Neighborhoods -- Oregon -- Portland




Gentrification and stagnation are two prominent themes in neighborhood development today. The city or Portland, Oregon is experiencing both of these neighborhood stages in different neighborhoods. In Oregon a property tax measure passed in 1997, Measure 50, caused property tax rates to vary by location according to changes in real market values over time. Recent analysis has revealed that property tax rates in Portland follow the spatial patterns of gentrification and stagnation in Portland, and therefore could be contributing neighborhood change. Differential property tax rates have shown to influence mobility and homeownership, two factors of neighborhood change. In order to see if property tax rates are indeed contributing to neighborhood change this study conducts two main analyses on three neighborhoods of varying property tax ranges. The first is a comparison of socio-­economic changes, based on census data, in the three neighborhoods to see how they relate to property tax rates. The second is an examination of urban policies established in the mid-1990s to see if there were any political and developmental drivers of this change. This preliminary study finds that property taxes are related to the socio-­economic and political influencers of neighborhood change and are likely a catalyst.
