Offsetting the declines in the food and energy indexes in April was a 0.3-percent increase in the index for all items less food and energy. Over 40 percent of the increase was due to a second consecutive large increase in the tobacco index. The index for all items less food and energy has risen 1.9 percent over the past year.
For the 12-month period ending in April 2009, the CPI-U decreased 0.7 percent, as shown in the chart. The year-over-year declines in March and April are the first since 1955.
