The Chained Consumer Price Index for All Urban Consumers (C-CPI-U) is a monthly measure of the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services. The C-CPI-U employs a formula that reflects the effect of substitution that consumers make across item categories in response to changes in relative prices. Index data are available for the U.S. City Average (or national average) only. Indexes are available for the all items index and for selected major subcomponents and aggregates.
This tool lets users query the BLS databases for specific data series. For each survey and program, make a selection for each characteristic in the order listed. As you make your selection, the remaining characteristics will filter to show only choices where data are available. After choosing the series, click on “Add to selection.” If you need more data series, repeat the steps of choosing the data series you need. After you've finished finding the data series you need, click on the “Get Data” button to retrieve the data, and an HTML table with data for the most recent 10 years will display. If you desire a different time period or format, you may modify the options on the data display page, or click on the “More Formatting Options” button for additional options on refining the data retrieval results. Note: Users may not retrieve more than 200 data series in one query.
Type all or part of a search string in the search text box. The contents of the box will filter to show only those options that contain the search string.
