Footnotes: (1) Indexes were not published in October 2025 due to a lapse in appropriations. Data for survey based indexes was not completely collected and October 2025 index values will remain suppressed for survey based indexes. For this reason, three and twelve month percent changes and standard errors do not include October and one month percent changes and standard errors do not include October and November. For further information on affected indexes see https://www.bls.gov/mxp/notices/2026/availability-of-oct-2025-mxpi-in-bls-database.htm. (2) Indexes calculated with over 50% non-sampled price data from one or more alternative data sources will not have a variance primarily due to sampling and have been excluded. (3) Index was not published the previous year. Estimates using prior year index values are excluded.
