This visualization works very well for presenting the ethnographic case. It shows the contradictions of Austin's "environmentally-conscious" reputation combined with policies of gentrification and exclusion, particularly against Latinos and blacks residents.
This image draws attention to how a discourse of how urban placemaking (and attendant marketing) is bound up with a politics of race. The image directly represents how a largely white population will be discursively linked to "best places to live". The production of place through race is arguably emblematic of how non-white populations become symbolic of 'pollution' thereby associated with the 'diminishing' of the liveability of a place. Such populations become, as Mary Douglas puts it, constructed as "matter out of place."
