For the second month in a row, the substantial increase in the all items index was mostly the result of an increase in the gasoline index, which rose 7.0 percent in September after increasing 9.0 percent in August. The other major energy indexes increased in September as well.
The food index increased 0.1 percent in September; the index for food at home was unchanged as major grocery store food indexes continue to be mixed. The index for all items less food and energy rose 0.1 percent for the third month in a row. Indexes for shelter, medical care, apparel, and airline fares were among those that increased, while the indexes for used cars and trucks, new vehicles, personal care, and household furnishings and operations all declined.
The 12-month change in the index for all items was 2.0 percent in September, an increase from the August figure of 1.7 percent and the highest since April. The index for all items less food and energy also rose 2.0 percent for the 12 months ending September; the food index has increased 1.6 percent and the energy index has risen 2.3 percent over that span.
