The economic changes that occur as a community goes through gentrification are often favorable for local governments. Affluent gentrifiers expand the local tax base as well as support local shops and businesses, a large part of why the process is frequently alluded to in urban policies. The decrease in vacancy rates and increase in property value that accompany the process can work to stabilize a previously struggling community, restoring interest in inner-city life as a residential option alongside the suburbs. These changes can create positive feedback as well, encouraging other forms of development of the area that promote general economic growth.
