December 2021 Consumer Price Index — 2022-01-12

The Consumer Price Index for All Urban Consumers (CPI-U) increased 0.5 percent in December on a seasonally adjusted basis after rising 0.8 percent in November, the U.S. Bureau of Labor Statistics reported today. Over the last 12 months, the all items index increased 7.0 percent before seasonal adjustment. Increases in the indexes for shelter and for used cars and trucks were the largest contributors to the seasonally adjusted all items increase. The food index also contributed, although it increased less than in recent months, rising 0.5 percent in December. The energy index declined in December, ending a long series of increases; it fell 0.4 percent as the indexes for gasoline and natural gas both decreased. The index for all items less food and energy rose 0.6 percent in December following a 0.5-percent increase in November. This was the sixth time in the last 9 months it has increased at least 0.5 percent.
