Gas prices rose more slowly in March, keeping overall U.S. inflation mild. The consumer price index rose 0.3 percent in March, the Labor Department said Friday. That's slower than February's 0.4 percent rise.
The Consumer Price Index, which measures inflation, is only as effective as the assumptions it makes -- in this case, about what you buy. If you spend more on certain things than most people, then the CPI will do a terrible job of reflecting the prices you actually pay. In particular, retirees often don't fit the CPI profile well at all.
