Core CPI, not seasonally adjusted, United States

Core CPI, not seasonally adjusted, is the consumer price index for all urban consumers excluding food and energy, in the form the Bureau of Labor Statistics first publishes it each month. Its series code is CUUR0000SA0L1E and its base is the 1982 to 1984 average, set to 100.

Its main use is as the base for the 12-month core inflation rate. Comparing a month with the same month a year earlier already cancels most seasonal effects, so the BLS calculates the year-on-year core rate from this unadjusted index, which, unlike the adjusted version, is not revised after publication. Researchers who need a stable history for long comparisons also prefer it for that reason.

Do not use it for changes from one month to the next. Even without food and energy, the remaining basket has seasonal habits: apparel prices fall with end-of-season sales, and some services reprice at the start of each year. A monthly fall in this index is often only the calendar. The seasonally adjusted core CPI page is the one for monthly momentum, while this page is the reference for annual comparisons and for checking the published 12-month core rate.
