Summary

  • Researchers joined an unnamed French operator's antenna-level service demand to results in 4,102 urban and suburban communes for the 2019 and 2024 European Parliament elections.
  • Adding mobile patterns raised the 2024 model's mean correlation with party vote shares by 28.23% relative to a socioeconomic baseline. The governance lever is access to the network's aggregate map.

The ballot box kept its seal. The network still had a map of the neighbourhood. At RIPE 93, Orlando Eduardo Martínez-Durive presented research that used traffic from a major French mobile operator to read political patterns across communes. No voting history travelled through a phone. The input was demand for broad classes of mobile services at cell antennas; the output was a comparison with public vote shares.

The authors' original IMC 2026 paper covers the weeks before the 2019 and 2024 European Parliament elections. One unnamed operator supplied data from two brands on a shared backbone, representing 31.9% and 31.5% of the French mobile market in those years. Researchers allocated antenna traffic to 4,102 urban and suburban communes and joined it to official election totals and age, income and unemployment measures. The selected communes contain about 66% of eligible voters; rural areas sit outside this model.

The original paper PDF reports a 28.23% relative gain in the 2024 model's mean correlation with party vote shares when mobile-service variables join the socioeconomic baseline. That is a change in model fit, not a count of persuaded voters. The unit is a commune. The network records service demand, not the words on a screen or a person's marked ballot.

Here the operator's ordinary engineering vantage becomes a political instrument. The paper's authors want researchers and public overseers to use such aggregate signals without relying on platform data feeds. That promise comes with a control question: the operator holds the raw traffic, the analyst draws the cell-to-commune boundaries, and the resulting map can travel far beyond the network team. The election story is in that handoff.
