Where the money goes
The €18.8M spent in 2025, by who receives it.
Source: the town’s 2025 accounts (DGFiP).
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 town in 2025: €8.1M (its accounts).

Why this total differs from the €8.1M 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
€3M of capital spending in 2025 (building, renovation, equipment), €272 per resident. Towns of the same size: €363.

Per resident: amount divided by the total population (Insee, in force in the year of the accounts).

Who spends for the residents of Chantilly
Spending per resident in 2025 of each public body the town belongs to, and what each one pays for.
- TownChantillyPrimary schools, canteens, local streets, civil registry€1,709 per resident
- IntercommunalityCommunauté de communes de l'Aire CantilienneWaste, water, urban transport, economic development€389 per resident
- DépartementOiseMinimum income, elderly and disability care, middle schools, county roads€1,117 per resident
- RegionHauts-de-FranceHigh schools, regional trains, training, business support€628 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
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 towns of 10,000 to 20,000 inhabitants are ranked from lowest to highest value; the median is the value in the middle. A value above or below the median is not a judgement: it depends on the area, the population and the powers held by the intercommunality.
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.
