Where the money goes
The €355.2M 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: €104M (its accounts).

What the town paid in 2025 for these kinds of purchase, from its accounts
- Maintenance and repairsall suppliers together · contract in the list: Otispaid €5.8M
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 €104M 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
€48.6M of capital spending in 2025 (building, renovation, equipment), €324 per resident. Towns of the same size: €340.

Debt and taxation
Accounts 2025, main budget (excluding annex budgets such as water), except debt and savings: main and annex budgets together (OFGL consolidated accounts). Per resident: amount divided by the total population (Insee, in force in the year of the accounts). Sources: DGFiP, OFGL. “Towns of the same size”: median of the 41 towns of 100,000 inhabitants and over.
Who spends for the residents of Saint-Denis
Spending per resident in 2025 of each public body the town belongs to, and what each one pays for.
- TownSaint-DenisPrimary schools, canteens, local streets, civil registry€2,371 per resident
- IntercommunalityPlaine CommuneWaste, water, urban transport, economic development€804 per resident
- DépartementSeine-Saint-DenisMinimum income, elderly and disability care, middle schools, county roads€1,203 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
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 100,000 inhabitants and over 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.
