Note: These are subject to change as the statement of work is updated.
CNSTAT will convene an expert panel and hold a workshop. Both the panel kickoff and the workshop will be open to the public and will be announced in advance on the BLS website. The panel will then spend about a year in internal discussions and preparing a written report for our consideration.
Additional information is available in the Commissioner’s Corner blog Improving the Accuracy of the Consumer Price Index.
