The Data

In an analysis conducted jointly by Statistics Belgium, Eurostat and Proximus, researchers accessed Belgian mobile phone data (from the major network operator, Proximus) and compared it to results of the 2011 Census.

How the data was shared

The paper produced from this research attempted to find the accuracy of mobile phone data as a measure of resident population density in Belgium. The anonymized and aggegated mobile phone data was obtained from Proximus. For each transaction on Proximus's mobile network, the mobile phone location was located to the level of a cell identity. A heatmap was then created showing the number of devices in each area, on the basis of localizations by the mobile network. Data were recorded every 15 minutes for one weekday.

Purpose of Data Shared

These researchers attempted to find whether mobile phone data could be tested for internal consistency and compared to results of the 2011 Census. Results showed that mobile phone data was "shown to provide valid and accurate information which may serve as a complement to traditional statistics, but also as an entry point in real time to phenomena inaccessible until now."
