It is the Consumer Price Index for All Urban Consumers for all items, U.S. city average, seasonally adjusted, published by the BLS and available on FRED. The published value is an index level (1982-84 = 100), not a direct percent inflation reading.

How do you compute MoM and YoY?

Month-over-month change uses the latest index and the prior month’s index from the same FRED series: (latest / prior − 1) × 100. Year-over-year uses the latest index and the observation 12 months earlier in the monthly series (the 13th point when sorted newest-first).

Is this the same as the headline CPI news number?

It is based on the same broad CPI-U SA index family, but news outlets may highlight different slices (e.g. core CPI excluding food and energy). This page focuses on the all-items SA index level from CPIAUCSL.

Why might the observation date look old?

CPI is released monthly. FRED updates when BLS publishes; the latest row’s date is the reference month for that index reading.

Methodology & source

CPIAUCSL is the Consumer Price Index for All Urban Consumers: All Items in U.S. City Average, seasonally adjusted (index level, 1982-84=100). Month-over-month (MoM) and year-over-year (YoY) changes are computed from consecutive FRED observations in the monthly series (YoY uses the observation 12 rows earlier in the descending list, i.e. approximately 12 months prior). This is an educational snapshot, not a forecast or trading signal.
