The 0.4-percent seasonally adjusted increase in the August CPI-U was driven by a 9.1-percent rise in the gasoline index. This increase accounted for almost the entire advance in the energy index and more than 80 percent of the overall increase. Despite the August increase, the gasoline index has fallen 30.0 percent over the last 12 months.

The indexes for food and for all items less food and energy both posted slight increases in August. The food index rose 0.1 percent following a 0.3-percent decline in July. The food at home index, which fell 0.5 percent in July, was unchanged in August. Of the six major grocery store food group indexes, three rose in August and three declined. The index for all items less food and energy also rose 0.1 percent in August, the second consecutive such increase.

The index for all items less food and energy increased 1.4 percent over the last 12 months, the smallest 12-month increase in the index since February 2004.
