Year-on-year, the energy index fell 16.3 percent over the last 12 months, with the gasoline index down 25.0 percent despite rising in May. The food index increased 1.6 percent over the last year, and the index for all items less food and energy rose 1.7 percent.
On a monthly basis, the gasoline index increased sharply in May, rising 10.4 percent and accounting for most of the seasonally adjusted all items increase. Other energy indexes were mixed, with the fuel oil index rising but the electricity index declining and the index for natural gas unchanged. The food index was unchanged for the second month in a row, as a decline in the food at home index offset an increase in the index for food away from home.
The index for all items less food and energy rose 0.1 percent in May, its smallest increase since December. The indexes for shelter, airline fares, and medical care all increased, as did the indexes for personal care, recreation, new vehicles, alcoholic beverages, and tobacco. In contrast, the indexes for apparel, for household furnishings and operations, and for used cars and trucks all declined in May.
