Salary adjustment The INPC directly influences the lives of many Brazilians as the 12-month rolling accumulation is usually used to calculate salary adjustments for different categories throughout the year. The minimum wage, for example, takes November data in its calculation. Unemployment insurance, the INSS ceiling and the benefit for those who earn above the minimum wage are readjusted based on the result of the INPC accumulated until December. Official inflation IBGE also released the Broad National Consumer Price Index (IPCA), known as official inflation. In May the index was 0.58%, accumulating 4.72% in 12 months.  The difference between the two indices is that the INPC calculates inflation for families with incomes of one to five minimum wages. The IPCA, for households with income from one to 40 minimum wages. Currently the minimum is R$1,621.  According to IBGE, the INPC calculation “aims to correct the purchasing power of salaries, through price variations in the consumption basket of the salaried population with the lowest income”. The institute gives different weights to the price groups researched. In the INPC, for example, food represents around 25% of the index, more than in the IPCA (approximately 21%), as lower-income families spend proportionally more on food. From the opposite perspective, the price of a plane ticket weighs less on the INPC than on the IPCA. Price collection is carried out in ten metropolitan regions: Belém, Fortaleza, Recife, Salvador, Belo Horizonte, Vitória, Rio de Janeiro, São Paulo, Curitiba and Porto Alegre. Collection is also carried out in Brasília, Goiânia, Campo Grande, Rio Branco, São Luís and Aracaju.
