Cities and Big Data. Edward Glaeser, September 2019, Paper, “Historically, there has been a divide between urban economics and the physical aspects of the city itself. Social scientific research has been detached from subjects such as architecture and streetscapes. This lack of connection has been driven in part by a lack of data on the physical attributes of urban spaces. The “big data” revolution will change this. Big data turns a cross section of space into living data, offering a broader and finer picture of urban life than has ever been available before. Moreover, in combination with predictive algorithms, big data may allow us to extrapolate outcome variables such as house prices or income to previously unmeasured parts of a population. This policy brief showcases some examples of how big data can be used to develop cities.Link
