Since 2014 Paris lets residents propose and vote online on how to spend about 5% of its municipal investment budget. The 2024 edition drew 142,938 voters and funded 121 projects (~€83M); the 2025 round funded 104. Over 3,500 projects have been delivered. No 2026 edition — paused for the municipal elections.
what does this mean?
The strongest source is the operator's or the city's own reporting — an official report, dataset or press release. It grades who did the looking — not how well the project went. All four grades →📊 Impact
2024 edition: 142,938 Parisians voted and 121 winning projects (~€83M) were selected; the 2025 edition funded 104. Since 2014 the city reports 3,500+ delivered projects, drawn from roughly 5% of its investment budget.
🎓 Lesson
Participation is real but partial — even a record 142,938 voters is a small share of ~2M residents, so headline turnout should not be read as broad representativeness.

The participation platform, and what happened after the launch
Four cities put proposals and budgets online, three of them on software another city wrote. The interesting part is not the launch — it is what the same city's own data says a few years later.
