The Rise and Fall of the G.D.P.

Whatever you may think progress looks like — a rebounding stock market, a new house, a good raise — the governments of the world have long held the view that only one statistic, the measure of gross domestic product, can really show whether things seem to be getting better or getting worse. G.D.P. is an index of a country’s entire economic output — a tally of, among many other things, manufacturers’ shipments, farmers’ harvests, retail sales and construction spending. It’s a figure that compresses the immensity of a national economy into a single data point of surpassing density. The conventional feeling about G.D.P. is that the more it grows, the better a country and its citizens are doing. In the U.S., economic activity plummeted at the start of 2009 and only started moving up during the second half of the year. Apparently things are moving in that direction still. In the first quarter of this year, the economy again expanded, this time by an annual rate of about 3.2 percent.

All the same, it has been a difficult few years for G.D.P. For decades, academics and gadflies have been critical of the measure, suggesting that it is an inaccurate and misleading gauge of prosperity. What has changed more recently is that G.D.P. has been actively challenged by a variety of world leaders, especially in Europe, as well as by a number of international groups, like the Organization for Economic Cooperation and Development. The G.D.P., according to arguments I heard from economists as far afield as Italy, France and Canada, has not only failed to capture the well-being of a 21st-century society but has also skewed global political objectives toward the single-minded pursuit of economic growth. “The economists messed everything up,” Alex Michalos, a former chancellor at the University of Northern British Columbia, told me recently when I was in Toronto to hear his presentation on the Canadian Index of Well-Being. The index is making its debut this year as a counterweight to the monolithic gross domestic product numbers. “The main barrier to getting progress has been that statistical agencies around the world are run by economists and statisticians,” Michalos said. “And they are not people who are comfortable with human beings.” The fundamental national measure they employ, he added, tells us a good deal about the economy but almost nothing about the specific things in our lives that really matter.

In the U.S., one challenge to the G.D.P. is coming not from a single new index, or even a dozen new measures, but from several hundred new measures — accessible free online for anyone to see, all updated regularly. Such a system of national measurements, known as State of the USA, will go live online this summer. Its arrival comes at an opportune moment, but it has been a long time in the works. In 2003, a government official named Chris Hoenig was working at the U.S. Government Accountability Office, the investigative arm of Congress, and running a group that was researching ways to evaluate national progress. Since 2007, when the project became independent and took the name State of the USA, Hoenig has been guided by the advice of the National Academy of Sciences, an all-star board from the academic and business worlds and a number of former leaders of federal statistical agencies. Some of the country’s elite philanthropies — including the Hewlett, MacArthur and Rockefeller foundations — have provided grants to help get the project started.
