145 contracts signed in 2025 · €340.5M before tax
Why this total differs from the €504M paid to companies
These are the amounts of the contracts signed in the year, over their whole length, not what was paid. The money paid in a year also goes to older contracts and to purchases too small to be published (under €40,000 excl. VAT). For a framework agreement, the amount is a ceiling.
Investment and works
€299.2M of capital spending in 2025 (building, renovation, equipment), €180 per resident. Départements of the same size: €93.

- RegionÎle-de-FranceHigh schools, regional trains, training, business support€459
Each row: the body’s own spending per resident, the figure at the top of its page (DGFiP). Not to be added up: a grant from one level is spent by another.

Understanding these figures
Who does what
The département pays for middle schools, social help (minimum income, elderly care, disability, child welfare), départemental roads, and funds the fire and rescue service.
Why the levels are not added up
The same euro can appear twice: once when a region or a département pays a grant, again when the town spends it. Each page shows its own body’s spending.
Where these figures come from
Spending: the accounts of the main budget published by the DGFiP, by public policy. Revenue, debt and taxes: OFGL. Contracts: published contract data (DECP), amounts planned at signing.
