Consumer Price Index: New basket weights, 2023 update
Updated basket weights for the goods and services in the Consumer Price Index (CPI), representing consumer spending patterns in 2022, are now available. The 2022 basket will combine expenditure data from the Household Final Consumption Expenditures, the Survey of Household Spending and alternative data sources to account for shifts in spending.
The updated weights will be incorporated into the May 2023 CPI, which will be released on June 27, 2023. They will replace the previous weights, which were based on 2021 expenditure patterns.
The weight reference period for the new basket is 2022. The index base period for the all-items CPI remains 2002=100.
