Source: BLS, CPI for All Urban Consumers (CPI-U): U.S. city average, Seasonally adjusted changes from preceding month, All items less food and energy.

For example, "The index for all items less food and energy rose 0.4 percent in February, as it did in January."

Resolves based on the initial release (i.e. subsequent revisions don't affect resolution). Resolves to the reported number rounded to the nearest tenth of a percent. [edit: this will resolve to a single bucket based on the percent change; apologies for the change but I think that’s best given how this market type works]

Reported on May 15 (question closes just before release).
