[OC] How Paris spends Parisian money: a per-capita breakdown of the city’s EUR 11.7B budget

Paris publishes its budget data as raw CSVs and PDFs.

We built an open-source platform that transforms this into interactive visualizations anyone can explore.

This chart breaks down the city's budget into 11 thematic categories and shows how much each Parisian effectively "pays" per day. The biggest slices: personnel & admin, social services, and urban planning.

Key numbers (2026 budget):

– Budget per resident: ~EUR 5,242/year — about EUR 14.40/day
– Largest category: Personnel & Admin (21.6%)
– Second: Action Sociale — social services (19.7%)
– Capital projects: EUR 2.2 billion
