Methodological description
It reflects changes in market prices of residential premises purchased by households in the reporting quarter in relation to their prices in the previous quarter.
It is compiled on the basis of information obtained from Registers of Real Estate Prices and Values, kept by powiat starosta offices and mayors of cities with powiat status, and using the data derived from notarial deeds.
Price index of residential premises is compiled using stratification method, that consists in dividing transactions into possibly homogeneous groups. Stratification is based on market segment (new/existing premises), premises location and size. An elementary-level index is computed for each strata as a quotient of the average price in the current period and the average price in the base period. Indices for higher aggregation levels are calculated using a Laspeyres’ formula with a weight system from the previous year.
