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. The city counts more than 3,400 finished worksites. No 2026 edition — paused for the municipal elections.

📊 Impact

2024 edition: 142,938 Parisians voted and 121 winning projects (~€83M) were selected; the 2025 edition drew 162,395 voters and funded 104. Since 2014 the city counts 1,345 winning projects, more than 3,400 completed worksites and €768 million, drawn from roughly 5% of its investment budget.

🎓 Lesson

Participation is real but partial: even the 2025 edition's 162,395 voters are a small share of Paris's 2.1 million residents, and the city reports winners, finished worksites and euros rather than what the projects changed. A peer-reviewed study of the 4,043 projects financed from 2014 to 2021 concluded the budget may work mainly as political communication.

Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The city's dossier gives key figures since 2014 and says residents vote in ballot boxes across the city and online on decider.paris.fr; CityMonitor dates the first edition to 2014.
Caveat
Voting is also held at ballot boxes (505 in 2025), not only online.

CityMonitor (2021) says residents decide how to spend €100m, around 5% of Paris's annual capital budget.

The share is from 2021; the 2024 edition allocated about €83 million, and the city now frames the budget as part of a quarter of investments co-decided with residents.

The 2025 page gives 162,395 voters; INSEE counts 2,103,778 residents of the Commune de Paris in 2023.

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.
