Economic and policy research can often suffer from a scarcity of up-to-date data sources. This column explores the potential for digital data to supplement official government statistics by providing more up-to-date snapshots of the economy. A comparison of data from Yelp with US County Business Patterns data reveals that the Yelp data provide a good indication of underlying economic trends.
