Big data, official statistics and measuring the economy
The multiplication of the digital traces generated by the activity of individuals or companies, and the growing capacity to store and analyse them, have given rise to the “big data” phenomenon. Using large quantities of individual data is obviously nothing new to official statistics which process data from surveys, the census and a wide variety of administrative sources.
However, the advent of big data does bring two major shifts in the form of much larger data volumes and almost-immediate access. There are a number of obstacles, nonetheless, to making the most of these advantages, as these data are not always without their defects: their formats are complex and highly variable, using them can require costly technical investments, their representative nature is not always guaranteed and the same applies to their predictive power.
This focus proposes a review of the contribution of these data to three aspects of the measurement of the economy. First of all, short-term monitoring: does analysis of internet search behaviour or of the online press enable us to anticipate the short-term climate more effectively than survey data do? As things stand, the response to this question remains somewhat reserved.
The second aspect is tracking of prices. In this respect, the contribution of big data is already shown to be more tangible, whether in the form of prices collected on internet or of scanner data provided by retail chains. Finally, a presentation will be made of a number of attempts to use big data to quantify the phenomenon of which they are one of the manifestations, the boom in the digital economy sector.
