Increases in shelter and food indexes outweighed declines in energy indexes to result in the seasonally adjusted all items increase. The food index rose 0.3 percent as five of the six major grocery store food group indexes increased. The energy index declined 0.7 percent as the indexes for gasoline, electricity, and fuel oil all fell.
The index for all items less food and energy increased 0.1 percent in September. Along with the shelter index, the index for medical care increased, and the indexes for alcoholic beverages and for personal care advanced slightly. Several indexes were unchanged, and the indexes for airline fares and for used cars and trucks declined in September.
The all items index increased 1.7 percent over the last 12 months, the same increase as for the 12 months ending August. The 12-month change in the index for all items less food and energy also remained at 1.7 percent. The 12-month change in the shelter index has been gradually increasing, and reached 3.0 percent for the first time since January 2008. The food index has also risen 3.0 percent over the span, while the energy index has declined 0.6 percent.
