There is no comprehensive approach for measuring gentrification tendencies in different neighbourhoods spread over a city, especially in the context of Germany. This work develops a framework that quantifies change in the relevant dimensions and sets up a gentrification typology. It is demonstrated here for Munich and the development in the period between 2008 and 2012.
The socio-demographic dimension represents change in the social status of the local population, the residential-economic dimension reflects change in type and affordability of the local housing supply that is offered on the website of ImmobilienScout24. They represent the driving forces behind gentrification, both dimensions are equally necessary to determine gentrification areas. The proposed gentrification typology assigns each neighbourhood one of the following types:
The legend on the right side contains a horizontal direction that indicates the development in the socio-demographic dimension and a vertical one that indicates the development in the residential-economic dimension. Strong gentrification tendencies are indicated by approaching the top-right corner, while the category in the bottom-left corner represents neighbourhoods that exhibit no signs of gentrification. Hovering the different categories in the legend highlights the respective neighbourhoods in the map and the scatter plots.
For more details on the difference between actual and relational upgrading and the applied algorithms that result in the two indices for each neighbourhood, have a look at the thesis. It was supervised by Dr. Andrej Holm and is part of the GentriMap Project he initiated in Berlin.
