About this Dataset
The Consumer Price Index for All Urban Consumers (CPI-U) is the most widely referenced inflation gauge in the United States. Published monthly by the U.S. Bureau of Labor Statistics (BLS), it measures price changes in a fixed basket of goods and services representing the expenditures of approximately 93% of the US population.
The CPI is often used as the benchmark for inflation adjustments in financial contracts, government benefit programs, and monetary policy frameworks.
- Coverage: All urban consumers (CPI-U) — approximately 93% of the US population
- Frequency: Monthly, released mid-month for the prior month
- Base period: 1982–84 = 100
- Geographic scope: 87 urban areas across the United States
- Data history: January 1947 to present (955+ observations; BLS back-estimates available to 1913)
- Revision policy: Subject to seasonal adjustment revisions each February
The weights assigned to each expenditure category are updated periodically based on Consumer Expenditure Surveys (CE). Since 2023, weights are updated annually using a two-year average of expenditure data, improving the index's responsiveness to shifting consumption patterns.
BLS did not publish an October 2025 CPI reading because of the federal government shutdown that month, so the chart and table below skip directly from September to November 2025. The Q4 2025 row therefore averages November and December only. The Q3 2026 row averages July and August only, since the September 2026 release had not yet posted as of this update. In both partial rows, the headline and core growth rates compare against the same months a year earlier.
