The BLS December chain over the member components (index Jan 2018 = 100), the aggregation the headline Gauge uses under method v1.5: each year’s relative-importance weights multiply price relatives since the previous December, and the year-over-year change joins the year-ago-to-December segment to the December-to-today one. A component priced on a monthly source compares that source’s latest month with the same month a year earlier, and takes the official subindex while BLS has published a newer month. The whole history on this page is computed under this method. Each contribution is the component’s exact share of the category’s year-over-year change; they add up to the reading. Core = every component except food and energy. Live inputs: the all-tenant rent index on both shelter weights, Manheim wholesale values for used vehicles (30-day lag) and Kelley Blue Book transaction prices for new vehicles, each vehicle source only while its latest month is at least as new as the BLS print (an older one steps aside for the official subindex; the drivers table shows which are live today); medical, apparel, recreation, education & communication and everything else hold their official subindexes between prints.

The official subindex is quoted at the last print (NSA, one decimal). The daily reading is a measurement of today; the like-for-like comparison is the calendar-month average of the daily series for the print’s reference month (at_print_month_pct), which is what the gap-at-print figure uses. Components: shelter_rent, shelter_owned, used_vehicles, new_vehicles, medical, apparel, recreation, education_comm, other, transportation_services, lodging, household_furnishings, water_sewer_trash, alcohol, personal_care, tobacco; weights from the BLS CPI-U relative-importance table (engine weights.json) (2026). Engine construction v1.5.
