Hello.
"Official" government agency data is not to be trusted. It is a well-known fact that the numbers are "cooked" every single year. This data is usually masqueraded by Enron accounting-style gimmicks. Take for example inflation. It's a well-known fact that the people who calculate the final figures regularly remove those items, from the product basket from which inflation is calculated, that shoot off the chart in order to "massage" the figures downward. Note that these numbers are NEVER rounded up, but ALWAYS rounded down.
Believing what anyone says is optional, but finding it out for yourself should be mandatory.
