The Consumer Price Index increased 0.3 percent in September on a seasonally adjusted basis, the U.S. Bureau of Labor Statistics reported today. Over the last 12 months, the all items index rose 1.5 percent before seasonal adjustment.

Increases in the shelter and gasoline indexes were the main causes of the rise in the all items index. The gasoline index rose 5.8 percent in September and accounted for more than half of the all items increase. The shelter index increased 0.4 percent, its largest increase since May.

The energy index increased 2.9 percent, its largest advance since April. Along with the gasoline index, other energy component indexes also rose. The index for food, in contrast, was unchanged for the third consecutive month, as the food at home index continued to decline.

The index for all items less food and energy rose 0.1 percent in September after a 0.3-percent increase in August. Along with the shelter index, the indexes for medical care, motor vehicle insurance, and personal care all increased in September
