Mobilizing private data for statistical purposes will soon be easier

[badsha0025]

Eurostat continues to drive and coordinate innovative projects related to mobile phone data. The MNO-MINDS research project (2023-2025) brings together ten national statistical institutes (NSIs) to develop a common methodological framework for combining mobile phone data and other data sources (data collected by NSIs and data from other sources: road traffic sensors, public transport ticketing, etc.). Within the same timeframe, the multi-MNO project brings together statistical institutes and mobile phone operators from several countries (Spain, Italy, Slovenia, Luxembourg). The objective is to develop a reference technical process for combining data from different operators, while respecting the confidentiality of personal data. INSEE is heavily involved in this work, as the leader of a working group for the MNO-MINDS project and a member of the multi-MNO project advisory committee.

These two examples illustrate a new trend marked by the use of data held chinese overseas europe database by private actors. The digital transformation of society has indeed led to the emergence of numerous data sources, characterized by large volumes (data from the internet, sensors), varied formats (images, texts) and significant flows. User expectations have also changed, with new needs and growing demands for more detailed, more geographically refined information, produced more quickly and at a higher frequency. Alongside traditional data sources (surveys and administrative files), the exploitation of new private sources by statisticians makes it possible to respond to these new needs effectively (Dupont, 2023).
