Inflation (CPI, YoY)
Year-over-year change in consumer prices.
How to read CPI year over year
Headline CPI includes all items in the CPI-U basket. Core CPI excludes food and energy.
Each YoY percentage compares the price index with the same month one year earlier. The date shown for each value is its CPI reference month; release, publication, and collection dates describe later events.

Headline vs. core CPI gap
