The Brazilian city of Porto Alegre started the first full PB process in 1989, for the municipal budget. In Porto Alegre, as many as 50,000 people have participated each year, to decide as much as 20% of the city budget. Since 1989, PB has spread to over 1,500 cities in Latin America, North America, Asia, Africa, and Europe. In the US and Canada, PB has been used in Toronto, Montreal, Guelph, Chicago, New York City, and Vallejo (California).
Tiago Peixoto of the European University Institute has developed a GoogleMap to display global examples, using a broad definition of PB. There are over 1,500 cities and institutions implementing Participatory Budgeting (PB), and it is almost impossible to keep track of them all.
Mapped below by PBP are some of the most developed and interesting PB processes in North America, Latin America and Europe that illustrate the diversity of PB models. Click on the markers or use the sorting menu below the map to learn more about Participatory Budgeting processes.
