In October 2006 the annual inflation rate (CPI-U) was 1.31% and it was 50% higher at 1.97% in November. Yet on the same day the data was released Yahoo Financial News reported in an article entitled “Stocks Rise on Inflation Data”that Inflation was flat.
Their exact words were “The Labor Department said consumer prices were flat in November rather than up 0.2 percent as analysts had expected. Core inflation, which excludes volatile food and energy costs, was also unchanged.”
How can a 50% increase in the inflation rate be considered “flat”?
Well, interestingly the government publishes several sets of numbers. The first is the numbers that we use (and are most commonly used). This is the traditional “Inflation Rate” or CPI-U (Consumer Price Index for all Urban Consumers).
The Bureau of Labor Statistics also publishes a less commonly quoted CPI-W which is the Consumer Price Index for Urban Wage Earners and Clerical Workers. The basic component mix is slightly different.
In addition to these two traditional measurements of the Consumer Price Index the BLS also publishes two other numbers that have been massaged and twisted. They are the Chained Consumer Price Index for all Urban Consumers (C-CPI-U) and a Seasonally adjusted CPI-U.
It seems that the news media focused on the Seasonally adjusted numbers because the report from the Bureau of Labor Statistics says, “On a Seasonally Adjusted basis the CPI-U was unchanged in November.”
Seasonal adjustment sounds good in theory because at certain times of the year inflation is worse than at others but in reality I would rather take my data straight and come to my own conclusions rather than have the BLS and the news media cover up a 50% increase under the guise of “seasonal adjustment”.
