Activity Reports

In 2025, the Institute continued to fulfil its mission of shedding light on major contemporary issues, against a backdrop of international tensions, an accelerated ecological transition and profound changes within French society.

The year was marked by analyses of key topics, including the impact of US tariffs, a study of high salaries and wealth, and an assessment of public schemes supporting energy-efficiency renovations. These projects demonstrate our commitment to informing and guiding public policy.

The report also highlights the technical and methodological innovations we have introduced. Among the key achievements, the comprehensive census of Mayotte and the Homeless Survey illustrate the Institute’s commitment to maintaining the highest standards while developing methodological and technical innovations.

It also presents our efforts to make statistical information accessible to everyone, notably through an increased presence on social media, a new version of the Insee Mobile app, and a website that continues to evolve to better serve our audiences. Finally, it looks back at the adoption of a new visual identity shared by Insee and the 16 Ministerial Statistical Officies (MSOs). This identity reinforces the unity of the Official Statistical Service (SSP) and its commitment to combining statistical rigour with dialogue with society.
