Comprehensive Approach Captures Both Price Changes and How Consumers Adapt Their Shopping, While Closely Tracking U.S. Government Inflation Measures
CHICAGO, November 12, 2025 (GlobeNewswire) — Numerator, a data and technology company providing insights into consumer behavior, will introduce a new, consumer-centric measure of inflation powered by its verified, item-level retail purchase data. Similar to the U.S. Bureau of Economic Analysis’ published indexes, this measure tracks price changes over time and captures how consumer buying behavior evolves alongside them.
An advance metric will be released on Thursday, November 13 at 8:30 a.m. ET, providing financial institutions, policymakers, and economists visibility into inflation trends across everyday consumer goods. The data cover approximately 20% of the consumption basket captured in the government’s Consumer Price Index (CPI) and Personal Consumption Expenditures (PCE) index, offering a reliable signal of retail price changes experienced by U.S. consumers.
Thursday’s data release will include:
- Month-over-month inflation change through October 2025
- Year-over-year inflation change through October 2025
- Cumulative inflation index since 2018
- Expenditure and product shares by sector covered in Numerator’s Consumer Price Index (CPI)
Numerator’s measure provides a comprehensive view of inflation by:
- Capturing how consumers adjust their shopping when prices change, including brand switching, downsizing, and shifts in where they buy.
- Using verified household purchase data from the demand side, providing visibility into consumer behavior.
- Drawing on item-level transactions from 200,000 geographically and demographically representative U.S. households, covering categories such as groceries, household goods, and health and beauty.
- Delivering a current view of inflation trends, with continuously captured household purchase data aggregated monthly.
The first public release of this data will be available on Thursday, November 13 at 8:30 a.m. ET at numerator.com/inflation.
