This page shows information on imputation in the Consumer Price Index.
For the Commodities and Services Survey, uncollected prices which are imputed from collected prices within the same item and geographic area are referred to as home cell imputation. Uncollected prices which are imputed from the previous month are referred to as carry forward imputation.
For the Housing Survey, non-vacant units with respondents previously reporting, but not currently reporting, receive non-interview imputation in the CPI. Vacant units that were previously occupied by renters are also imputed for use in estimation by separate methods.
Additional information on imputation is available from the Consumer Price Index program section of the BLS Handbook of Methods.
