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.

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)
