Participatory Budgeting — Letting Communities Decide Together

The Brazilian military dictatorship ended in 1985. Democratic governance in the country was, in practical terms, four years old when the Workers' Party (Partido dos Trabalhadores, PT) took office in Porto Alegre in 1989. Mayor Olivio Dutra and a coalition including Ubiratan de Souza — the political theorist often credited as PB's chief architect — faced a classic developing-city problem. A wealthy downtown. A vast periphery of favelas with no sewers, no paved roads, no schools, no clinics. A bureaucracy that had been designed to serve elites. Budgets that routinely disappeared into patronage and corruption.

They could have hired planning consultants. Instead, they built Orçamento Participativo — Participatory Budgeting.

The structure, in its mature form, worked like this:

1. The city was divided into 16 regions plus 6 thematic zones (transportation, culture, education, etc.). 2. Each region held annual open assemblies. Any resident could attend and vote. 3. Assemblies elected delegates — roughly one per ten voting attendees — to serve on regional councils. 4. Regional councils developed detailed priority lists based on community ranking: schools before parks, or sewers before street lighting, or whatever the region decided. 5. A city-wide Council of the Participatory Budget (COP) integrated regional priorities with technical feasibility and the overall budget. 6. The city government was required to fund the winners. Not "consider." Fund.

This last point is the load-bearing wall. Everything else is participatory theater without it.

The scale of engagement grew over time. First year: around 1,000 participants. By 2000: over 40,000 residents annually, from a city of 1.4 million. Roughly 15% of the city budget was allocated through PB — about $200 million per year.

The outcomes, documented in peer-reviewed studies (Marquetti, Santos, Wampler, and others) and independent evaluations including the World Bank's 2008 report:

- Sewer and water connections rose from 49% to 98% of households between 1989 and 2004. - The number of public schools doubled in ten years. - Child mortality fell substantially, tracked to gains in sanitation and basic health access. - Tax compliance actually rose, because residents could see where their money was going.

Porto Alegre was not a utopia. The PB process weakened after PT lost the mayoralty in 2004. The city's fiscal conditions deteriorated. The model proved politically fragile. But the innovation had already escaped.

Three scholars — Gianpaolo Baiocchi, Ernesto Ganuza, and Brian Wampler — have done the heaviest lifting documenting PB's spread and effects. Their 2014 book Participatory Budgeting in Latin America and subsequent work tracks over 3,000 PB implementations globally.

The consistent findings:

Trust in government rises among participants. A 2014 study by Wampler and Touchton analyzed Brazilian municipalities with and without PB, controlling for demographic and political variables. PB municipalities showed measurable declines in infant mortality, attributable to shifted spending priorities toward basic health infrastructure. Trust in local government in PB municipalities rose by multiple percentage points relative to matched controls.

Civic participation spreads beyond PB itself. Participants are more likely to join neighborhood associations, attend city council meetings, vote in local elections, and contact officials about non-budget issues. The German sociologist Claus Offe called this effect "civic spillover." PB teaches the skill of showing up, and the skill generalizes.

Spending priorities shift. Large-ticket prestige projects (stadiums, downtown revitalizations, convention centers) receive less PB-allocated funding than they would under conventional budgeting. Neighborhood-scale infrastructure, parks, libraries, community centers, and public health services receive more. The shift is not random. It's what happens when decisions move from people who negotiate with contractors to people who walk past the broken streetlight every night.

Inequality decreases — modestly, but consistently. Municipalities using PB over a decade show measurable reductions in health-access inequality, school-quality inequality, and basic-service inequality. The effects are not dramatic in any one year. They compound.

Corruption decreases. This finding, from Gonçalves's 2014 study in World Development, is one of the most robust. PB makes spending traceable in public forums. Contractors who previously operated through back channels have to submit to neighborhood review. Kickbacks become harder when the budget line is on a poster on a school wall.

NYCPB began in 2011 when four City Council members each committed roughly $1 million of their discretionary capital funds to a PB process. By 2018, it had grown to 31 participating districts out of 51, with over $38 million allocated annually through PB. More than 100,000 residents voted in 2018 — the largest democratic process below the state level in the country.

The wins were concrete. Security cameras in public housing. Laptops in school libraries. Playground renovations. Elevator repairs in aging schools. Benches at bus stops in neighborhoods where elderly residents had nowhere to sit.

But the scale stayed small. $38 million in a city budget of roughly $90 billion is 0.04%. NYC's PB reached more New Yorkers than any comparable civic process, but it controlled a trivial slice of what the city actually spent. When COVID hit in 2020, the City Council paused PB — and the pause revealed how little institutional power it had accumulated. Some districts restored PB afterward. Many did not.

The NYC experience teaches two things. First: PB can scale up in terms of people involved even in a vast city. Second: without dedicated revenue and institutional protection, it remains optional — and when crisis hits, the "optional" goes first.

Vallejo is a port city of about 120,000 in the Bay Area. In 2008 it became the largest U.S. city at the time to declare municipal bankruptcy. Trust in the city government was, in polling, at single-digit percentages.

In 2011 Vallejo passed Measure B, a sales tax increase. To build public support for the tax, the council committed 30% of the Measure B revenue — roughly $3.2 million per year — to a city-wide PB process. Every resident, not just citizens, age 14 and up, could vote. Ballots were multilingual. The process ran through 2016.

Funded projects included: street repairs across low-income neighborhoods, a community garden, library technology upgrades, small business assistance, senior center improvements, and neighborhood security lighting. The projects were not glamorous. They were what Vallejo residents said they actually needed.

An independent evaluation by the Participatory Budgeting Project and Public Agenda (2015) found:

- Participants were demographically more representative of Vallejo than voters in regular elections. Low-income residents, renters, and Latino residents participated at higher rates in PB than in general elections. - Participants reported a 17-percentage-point increase in trust of local government. - Participants were significantly more likely to attend city council meetings, contact officials, and vote in subsequent local elections.

Vallejo's PB paused after 2016 due to council composition changes and a shift in priorities. But the experiment established the feasibility of city-wide PB in the U.S. with meaningful financial scale.

Three structural barriers keep U.S. PB processes marginal.

1. Fragmented budgets. U.S. municipal budgets are heavily constrained by state law, federal pass-throughs, union contracts, debt service, and mandated spending floors. The "discretionary" portion is often 10-20% of the total. PB has to fit inside that already-small slice.

2. Council discretion is a prize. In NYC, council members' discretionary capital funds are the mechanism that gives rank-and-file council members a sense of delivering for their district. Asking them to hand that discretion to PB is asking them to give up the thing that keeps their constituents happy. Some do. Most don't.

3. Staff and process costs. Running a proper PB cycle — outreach, assemblies, delegate training, project vetting, vote administration — requires dedicated staff. Without a committed budget for the process itself, PB runs on volunteer and nonprofit capacity, which caps its reach.

The result is that PB in the U.S. has consistently remained a supplement to conventional budgeting rather than a restructuring of it.

This is the part the research has been slowly circling for thirty years and which now seems settled.

Political theorists from Madison to Schumpeter to Lippmann have, at various points, argued that ordinary people are not competent to make technical decisions about government — too busy, too uninformed, too swayed by emotion. This argument has always had a convenient corollary: the only people qualified to make decisions are those already positioned to make them.

PB tests that claim empirically. What it finds, repeatedly, is:

Participation builds competence. First-time PB participants do make rougher decisions — prioritizing high-visibility items over structural ones, underestimating maintenance costs, favoring near-term over long-term. But repeat participants converge toward decisions that are indistinguishable from, or sometimes better than, those made by professional planners. This is the "democratic learning curve" documented by Baiocchi and Ganuza.

Deliberation changes preferences in productive ways. Assembly participants, after hearing other neighborhoods' needs and engaging with engineers and city staff, consistently shift their votes. They rank things higher that they would not have considered before, and lower things that, in isolation, they would have prioritized. This is the "discovery" effect — you can't know what a city needs by yourself, but in the right structure, a group of residents can figure it out together.

The cognitive load is manageable. Critics argued PB would overwhelm participants with detail. In practice, the combination of delegate structures, professional staff support, and iterative processes means most participants only engage deeply with a few decisions. It's not that every resident becomes a budget expert. It's that the system aggregates local knowledge without requiring anyone to become a generalist.

The takeaway for the broader thesis of Law 1 — We Are Human — is that human political competence is not a property of individuals. It's a property of the systems we embed them in. Put a person in a broken system and they will behave badly and incoherently. Put the same person in a well-designed participatory system and they will often behave like a civic exemplar.

This is hopeful. It also reframes the problem. When we say "people don't care about politics" or "Americans don't participate" — we are describing an environment we built, not an innate trait of the population.

1. Find your discretionary lever. Most cities have some form of participatory process: community planning boards, capital improvement committees, school budget votes, transportation advisory councils. Pick one. Attend once. Notice the gap between "asking for input" and "letting residents decide." If there's no true-decision body in your city, that's your next project.

2. Practice the assembly. If you have a neighborhood association, HOA, church, workplace, or mutual aid group with any shared budget — run a PB process at that scale. Ten thousand dollars, twenty people, one evening. Assemblies, priorities, binding vote. Notice what happens to the conversation compared to the usual top-down allocation.

3. Read one budget. Download your city's current budget document. Look at how much is "mandatory" versus "discretionary." Locate your council district's allocation, if any. Most people have never done this. It takes less than an hour and changes how you think about local politics permanently.

If PB in the U.S. were to match its theoretical potential, a handful of shifts would need to happen:

1. State enabling legislation. Similar to how some states authorize charter schools or special districts, states could enable — or require — cities above a certain size to allocate a percentage of discretionary funds through PB. California and New York have both had proposals. None have passed.

2. Dedicated process budgets. PB needs roughly 5-10% overhead of the allocated funds to run properly. This funding has to come from somewhere other than the PB pool itself. A municipal democracy office, funded at a meaningful level, would be the institutional home.

3. Integration with existing democracy. PB should not replace elected representatives. But it should bind them — the PB vote should be funded automatically, without a council override. This is the Porto Alegre model. U.S. implementations have almost universally retained council override authority, which weakens the mechanism.

4. Scaled funding. 0.1% of the budget produces civic theater. 5% produces trust. 15% produces transformation. The minimum threshold for observable effects, per the Brazilian data, is around 3% of discretionary spending — sustained over multiple cycles.

5. Multilingual, multichannel outreach. PB only works when the participants are representative. Vallejo's multilingual ballots and in-person-plus-digital voting are the model. Processes that only reach English-speaking homeowners produce PB that only funds English-speaking homeowners' priorities.

If every eligible resident said yes — showed up once a year, for one evening, to decide a portion of their city's budget together with neighbors they would otherwise never meet — the effects compound beyond the budget itself. Trust rises. Corruption falls. Priorities reorient toward the actual conditions of ordinary life. And people, individually, learn something they cannot learn any other way: that their participation is not performative. That democracy can be something other than an election every four years and complaining the rest of the time.

Porto Alegre started with $15 million and a favela that had never had a paved road. They proved something that the political theorists had argued about for two hundred years without settling. Given real authority, ordinary people get good at using it.

The question for American cities is not whether PB works. The evidence is in. The question is whether the people who currently hold discretionary authority will share enough of it to find out what their neighborhoods already know.

Next action: find out if your city, council district, school board, or neighborhood association has any participatory budgeting process at all. If not, ask — in writing — why not. That question, asked persistently by enough residents, is how most PB processes started.
