Overview
- Fieldwork has started across roughly 8,000 communes, with most local campaigns running from mid‑January to mid‑February and larger towns carrying sample surveys that in some cases continue to February 21.
- Residents are contacted by trained municipal agents carrying official ID who provide secure online access codes or paper forms, and participation is compulsory under INSEE’s confidentiality rules.
- In Mayotte, an exhaustive count launched on November 27 has been extended to January 24 after 13 of 17 communes fell behind, with INSEE citing access difficulties, some refusals, and two reported assaults on agents.
- INSEE says agents’ materials are due by January 31 for the island, with control and verification phases continuing through February, provisional results expected by summer 2026, and final figures by year’s end.
- Municipalities are mobilizing locally—ranging from multi‑agent teams to town‑hall staff filling gaps—and this year’s questionnaire includes new items on parents’ birthplace, health‑related activity limitations, and telework.
