What Have We Learned about the Causes of Recent Gentrification?

Jeffrey Lin

Since 2000, increased gentrification in an expanding section of cities and neighborhoods has renewed interest from policymakers, researchers, and the public in the causes of gentrification. The identification of causal factors can help inform analyses of welfare, policy responses, and forecasts of future neighborhood change. We highlight some features of recent gentrification that popular understandings often do not emphasize, and we review progress on identifying some causal factors. A complete account of the relative contribution of many factors, however, is still elusive. We suggest questions and opportunities for future research.
