Title Nowcasting Gentrification Using Airbnb Data

Speaker Giovanni Quattrone, Department of Computer Science, Middlesex University, London

Abstract Census data fails to measure neighbourhood change in real-time since it is usually updated every ten years. This work shows that Airbnb data can be used to quantify and track neighbourhood changes. Specifically, we consider both structured data (e.g., number of listings, number of reviews, listing information) and unstructured data (e.g., user-generated reviews processed with natural language processing and machine learning algorithms) for three major cities, New York City (US), Los Angeles (US), and Greater London (UK). We find that Airbnb data (especially its unstructured part) appears to nowcast neighbourhood gentrification, measured as changes in housing affordability and demographics. Overall, our results suggest that user-generated data from online platforms can be used to create socioeconomic indices to complement traditional measures that are less granular, not in real-time, and more costly to obtain.
