Why this total differs from the €475k of purchases, services and works paid to companies
These are the amounts of the contracts signed from 2022 to 2023, over their whole length, not what was paid in 2025. The money paid in 2025 also goes to purchases too small to be published (under €40,000 excl. VAT). For a framework agreement, the amount is a ceiling.

Understanding these figures
Running costs and works: what is the difference?
Running costs are each year’s spending: wages, energy, upkeep, grants. Works create or renovate something that lasts: a school, a road, a sports hall.
How is the comparison with towns of the same size made?
The median is the middle value among towns of the same size. A value above or below it is not a judgement.
Where do these figures come from?
From the town’s accounts kept by the public accountant (DGFiP), the local finance observatory (OFGL) and public procurement data. Qipu changes no amount.
