Government statistics are about the last place one should look to find inflation, as they are designed to not show much. Over the last 35 years the government has changed the way it calculates inflation several times. According to the Web site Shadow Government Statistics, using the pre-1980 method, the Consumer Price Index would be over 9 percent, compared with about 2 percent in the official statistics today.
While the truth probably lies somewhere in the middle, this doesn’t even take into account inflation we ignore by using a basket of goods that don’t match the real-world cost of living. (For example, health care costs are one-sixth of G.D.P. but only one-sixteenth of the price index, and rising income and payroll taxes do not count as inflation at all.)
Why does the government understate rising costs? Low official inflation benefits the government by reducing inflation-indexed payments, including Social Security. Lower official inflation means higher reported real G.D.P., higher reported real income and higher reported productivity.
