Participatory Budgeting

A democratic process in which community members — not elected officials, not staff — decide how part of a public budget gets spent.

The Practice

Participatory budgeting (PB) began in Porto Alegre, Brazil in 1989, when Olívio Dutra won the mayoral election on a platform of popular participation and redirecting municipal resources toward disadvantaged neighborhoods. The city’s Workers’ Party had built organizational capacity through community groups over the prior decade; Dutra institutionalized that structure into a city-wide deliberative process where residents proposed, debated, and voted on capital expenditures. Sewage lines to informal settlements. Paving of unpaved streets. Libraries in neighborhoods that didn’t have them.

In its Porto Alegre form, PB was a full-cycle process: community assemblies where residents identified priorities, technical review where city staff assessed feasibility and cost, delegate elections, budget delegates who negotiated across neighborhoods, and public votes on final allocations. It took months and required sustained participation from thousands of residents. By the early 2000s, over 100 Brazilian cities had adopted versions of the model.

The global spread has been substantial. By 2024, an estimated 11,500 municipal PB processes have been implemented worldwide — in European cities, in New York, in Cambridge, in Seoul, in Nairobi. New York City’s PBNYC committed $24 million across 24 council districts in one recent cycle. Paris has allocated €75 million. The numbers are large enough to matter, if not always large enough to transform.

What It Teaches

The question of who shows up. The Porto Alegre process succeeded partly because it was embedded in existing neighborhood organizations with long roots. Turnout was meaningful. In many later implementations, participation rates are thin: studies of German PB processes found participation around 0.1%, and Chicago cycles have seen 1-3%. The numbers reveal the limits of the form when it’s not organically grounded. A PB process without pre-existing community infrastructure is asking people to show up for a meeting about money with people they don’t know. Many don’t.

Political will is load-bearing. Porto Alegre’s process ran for nearly three decades before the city’s political leadership shifted and suspended it. The infrastructure for PB — the assemblies, the delegate system, the budget cycle — was never embedded in law in a way that survived a change in administration. This is the core fragility of PB wherever it has been implemented: it depends on the mayor, or the council member, or the school principal continuing to support it. When support withdraws, the process goes with it, and the community members who spent years learning how to participate have no recourse.

PB-lite as absorption. As the model spread, critics identified a pattern of dilution. “PB-lite” describes processes that keep the vocabulary of participatory budgeting while stripping out the elements that made it meaningful: the budget allocation is trivially small, the proposals are pre-screened by staff, the vote is advisory rather than binding, the winning projects take years to implement (if they’re implemented at all). Residents who participate in PB-lite and see their priorities ignored or delayed learn a lesson about democratic participation that the organizers didn’t intend to teach.

The distinction between real PB and theater matters. Real PB allocates money that residents actually control, on a timeline that residents can track, with binding implementation. Theater PB surveys preferences, thanks participants, and returns to normal operations.

The Tension

PB asks a lot of people who are already busy. The Porto Alegre model succeeded partly because residents had compelling reasons to participate — the stakes were concrete, the outcomes were visible, and the organizing tradition was deep. Exported to contexts where those conditions don’t hold, PB can become one more meeting in a long list of meetings, attended mainly by the people who have time to attend meetings.

There’s also the question of what happens when communities make choices that experts think are wrong. If a neighborhood votes to spend its allocation on something a transportation planner considers inefficient, who wins? PB without genuine deference to community choices isn’t PB. But deference isn’t unlimited either — no community should be able to vote to exclude others from services they’re legally entitled to. Where the line is has to be negotiated in each context, and the negotiation is part of the work.
