CPI calculates the average change of prices paid by consumers for a fixed basket of goods and services compared to a base reference period. From January 2008, CPI is calculated on the new basket basis and includes all country territory. Weights of goods are calculated based in the results of the family budget questionary (October 2006-September 2007). Base period for calculating the index is December 2007=100. Data are updated according to the source institution revisions.
