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).
