In order to calculate IPCA-15, prices were collected from August 13 to September 13 and compared to those in force from July 14 to August 12, 2011. The indicator refers to families with a monthly income of one to forty minimum wages and encompasses the metropolitan regions of Rio de Janeiro, Porto Alegre, Belo Horizonte, Recife, São Paulo, Belém, Fortaleza, Salvador, Curitiba, and also Brasília and Goiânia. The methodology is the same as the one used for IPCA; the difference lies in the period of price collection.
