Item coverage: The goods and services included are limited to consumption expenditures and exclude investment items such as stocks, bonds and real estate, but include rent deposits. The 2010-base index is calculated on 481 items representing all goods and services purchased for daily life by households.

Price sample: Each month about 100,000 price quotes are obtained from approximately 26,000 outlets and the quotes are obtained by personal interview. About 10,500 housing units are contacted for data on rents.

Index computation: Laspeyres methodology.

Notes

At the subnational level, the CPIs cannot be used to compare prices between areas; they indicate price changes only over time.
