CPI-U: All items (U.S., not seasonally adjusted)

## What this measures

The price index for all items in the Consumer Price Index for All Urban Consumers (CPI-U), U.S. city average, not seasonally adjusted (1982–84 = 100). It is the level BLS uses for the 12-month changes in its monthly news release. January 1913 to September 2026 in Palanor.

## Why it matters

The broadest read on what households pay; the Fed, wage contracts and Social Security all key off CPI.

## How to read it

Read the 12-month % change, not the level: Palanor's CPI charts take it from this index. In September 2026 the index stood 3.7% above a year earlier. The not-seasonally-adjusted index is the right one for 12-month changes; month-to-month moves need the seasonally adjusted series (the fred_cpi_* rows).

## What it does not say

A price index, not a cost of living: it tracks a fixed basket re-weighted every year, so it does not follow every substitution households make. Shelter is measured from rents (owners’ equivalent rent), not house prices. BLS published no October 2025 index (the federal shutdown), so changes that would start or end in that month are missing.
