Extended National Consumer Price Index - IPCA and National Consumer Price Index - INPC
The National System of Consumer Price Indexes - SNIPC continuously and systematically produces consumer price indexes, having as collection units commercial and service-offering establishments, public service concessionaries and households (for the surveying of rent and condominium fees). The data collection period of INPC and of IPCA goes mainly from day 01 until day 30 of the month of reference. The target population of INPC includes families dwelling in the urban localities of the areas, with monthly income ranging from 1 (one) to 5(five) minimum wages, and whose head of the household is paid a salary for their main activity; and of IPCA includes families dwelling in the urban localities of the areas, with monthly income, from any source, ranging from 1 (one) to 40 (forty) minimum wages. Indexes for specific objectives are also produced, as it is currently the case of the Special Extended National Consumer Price Index - IPCA-E.
