Why this total differs from the €30.2M 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
€18.6M of capital spending in 2025 (building, renovation, equipment), €448 per resident. Towns of the same size: €372.

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 359 towns of 20,000 to 50,000 inhabitants.
Who spends for the residents of Boulogne-sur-Mer
Spending per resident in 2025 of each public body the town belongs to, and what each one pays for.
- TownBoulogne-sur-MerPrimary schools, canteens, local streets, civil registry€2,080 per resident
- IntercommunalityCommunauté d'agglomération du BoulonnaisWaste, water, urban transport, economic development€904 per resident
- DépartementPas-de-CalaisMinimum income, elderly and disability care, middle schools, county roads€1,344 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 20,000 to 50,000 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.
