In a 1968 speech, Robert F. Kennedy said that “[GDP] measures everything… except that which makes life worthwhile.” I think this statement was, and is, still deeply relevant. Both here in the U.S. and across the world GDP (Gross Domestic Product) is often used as a metric of a country and its citizens’ well-being. And it seems almost hardwired to associate a high GDP with a good economy and a good life. But what exactly is GDP and what might be some alternatives to it?
In technical terms, GDP measures the total value of final goods and services produced within a country’s borders and is defined as the net consumption by households, investments by businesses, government purchases, and purchases made by foreigners (Kurtzleben GDP). GDP is generally what people refer to when they say that one economy is larger or smaller than another. When an astute economist posits “the Chinese economy will surpass that of the United States by 2050” they are probably referring to growth as increase in GDP. I don’t pretend to think anyone believes that GDP is a perfect measure of a nation’s well being, any good data miner/harvester/observer knows that any attempt to measure something as large as the “health of an economy” will miss something. And for what it is supposed to measure, the GDP is great.
Returning to RFK’s statement from above, I wonder if measuring the material output of a nation isn’t the most important to measure. I mean, if the entire workforce of the U.S. was replaced by advanced humanoid robots with no need for food, sleep, or a living wage, I bet the GDP would be pretty high but it wouldn’t account for the millions of people who would be left destitute. So what are some alternative ways of measuring the well-being of a country?
One of the more prominent alternatives to GDP is what is referred to as Gross National Happiness or GNH. GNH is a metric used by Bhutan since the 1970s (Kurtzleben Proposals) to measure the mental, rather than material, well-being. Unlike GDP, GNH is not something that is calculated with objective analytics of economic output. Instead, the government of Bhutan issues a national survey that measures the well-being of its citizens across several areas from education to satisfaction with the government (Kurtzleben Proposals). This data is then supposed to be drive the nation’s policy (GNH Survey Report). I think this approach is really ambitious and falls quite neatly in line with measuring things that “make life worthwhile”. That said, I can imagine there might be some logistical and statistical issues in interpreting data that could be very subjective. Bhutan is, after all, a fairly small country. For the U.S. government, with its sprawling landmass, dozens of local education systems, disparate socio-economic classes, and population of over 300 million, a GNH would be an absolutely daunting task. In my opinion, this type of metric would be better implemented on a state level.
The Happy Planet Index, a project by the New Economics Foundation, is similar to the GNH. It is a measure of “sustainable well-being” comparing how efficiently the residents of a country use natural resources to achieve lives with high well-being (Happy Planet Methods). The HPI is calculated by comparing life expectancy, multiplied by experienced well-being as reported via survey, and the inequality of outcomes, all of which is divided by the country’s ecological footprint. This approach, combining both hard statistics and subjective survey responses, seems like it might be able to produce a more holistic summary of a country’s well-being and might be easier to conduct on a national scale.
If it wasn’t clear by now, I am fairly opposed to a reliance on measures of material production for reporting the well-being of a country. GDP is a measure of economic growth and it would be nice to have alternative measures more commonly reported. I find myself drawn especially to metrics that attempt to account for the inequities in life expectancy and self-reported happiness as there is a better chance this might better represent a greater proportion of the population. No metric is perfect, but I certainly think something like the Happy Planet Index has potential.
