  Gentrification and its resultant displacement are one of the many "wicked
problems" of social policy. The study of gentrification and displacement spans
half a century, concerns a variety of spatial, temporal, and social contexts,
and describes socio-political processes of across the globe and throughout
history. One current iteration of this field of inquiry are efforts to identify
"early indicators" of gentrification and/or displacement, or the creation of
"early warning systems" (EWS). The current work adds to scholarship on the
utility of developing an EWS by examining the methodological considerations
required for such systems to serve a justice-oriented preventative role.
