The Consumer Price Index increased 0.2 percent in May on a seasonally adjusted basis after rising 0.2 percent in April, the U.S. Bureau of Labor Statistics reported today. Over the last 12 months, the all items index rose 2.8 percent before seasonal adjustment.

The indexes for gasoline and shelter were the largest factors in the seasonally adjusted increase in the all items index, as they were in April. The gasolin index increased 1.7 percent, more than offsetting declines in some of the other energy component indexes and led to a 0.9-percent rise in the energy index. The medical care index rose 0.2 percent. The food index was unchanged over the month.

The all items index rose 2.8 percent for the 12 months ending May, continuing its upward trend since the beginning of the year. The index for all items less food and energy rose 2.2 percent for the 12 months ending May. The food index increased 1.2 percent, and the energy index rose 11.7 percent.
