Contracts state a maximum amount for their whole term, often several years. That amount differs from what was paid. Purchases, services and works paid to companies by the département in 2025: €230.3M (its accounts).

What the département paid in 2025 for these kinds of purchase, from its accounts
- Postageall suppliers together · contract in the list: L'Atelier du Courrierpaid €484k
The accounts say how much was paid for each kind of purchase, not to which company. A purchase paid by another public body (joint order, shared service) is not in them.
Why this total differs from the €230.3M of purchases, services and works 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
€173.4M of capital spending in 2025 (building, renovation, equipment), €116 per resident. Départements of the same size: €93.

Spending per resident in 2025, and what each level pays for.
- DépartementYvelinesMinimum income, elderly and disability care, middle schools, county roads€1,057 per resident
- RegionÎle-de-FranceHigh schools, regional trains, training, business support€465 per resident
Each amount is what the body spends per resident, from its accounts (DGFiP). Do not add them up: part of the money passes from one body to 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.
