Government Statistics: "Fairy Tales and Lies"

"Formally known as Walter J. Williams, my friends call me John. For more than 25 years, I have been a private consulting economist and, out of necessity, had to become a specialist in government economic reporting. One of my early clients was a large manufacturer of commercial airplanes, who had developed an econometric model for predicting revenue passenger miles. The level of revenue passenger miles was their primary sales forecasting tool, and the model was heavily dependent on the GNP (now GDP) as reported by the Department of Commerce. Suddenly, their model stopped working, and they asked me if I could fix it. I realized the GNP numbers were faulty, corrected them for my client (official reporting was similarly revised a couple of years later) and the model worked again, at least for a while, until GNP methodological changes eventually made the underlying data worthless.

That began a lengthy process of exploring the history and nature of economic reporting and in interviewing key people involved in the process from the early days of government reporting through the present. For a number of years I conducted surveys among business economists as to the quality of government statistics (the vast majority thought it was pretty bad), and my results led to front page stories in the New York Times and Investors Business Daily, considerable coverage in the broadcast media and a joint meeting with representatives of all the government's statistical agencies. Despite minor changes to the system, government reporting has deteriorated sharply in the last decade or so."

Mr. Williams is far too polite to call those reporting official government statistics lying rats. I'm not...
