Gentrification and a Golden Age of data

Sources such as Yelp can provide very immediate data on neighbourhood change, in contrast to official data sources which are very accurate but appear with considerable lag. Comparing data from Yelp with these official data, from a period where both are available, reveals that the Yelp data are more accurate for areas of higher density and general education level. Edward Glaeser, of Harvard University, investigates to what extent the Yelp data can be used to substitute the official data in periods for which they are not yet available, particularly when predicting gentrification of areas.
