In a report released Saturday, the group ranks nations using the "Happy Planet Index," which seeks countries with the most content people.
In addition to happiness, the index by the New Economics Foundation considers the ecological footprint and life expectancy of countries.
Happy Planet Index?! Prison rodeo!?
The New Economics Foundation is here. The intro page for the Happy Planet Index is here, and the pdf report itself is here. The final rankings are on page 63 of the pdf. Components of the Happy Planet Index are: Life expectancy, life satisfaction, and ecological footprint. The goal with the final metric is to achieve "one-planet living." I'm guessing they're against colonizing Mars.
I liked this one: "The planet’s overall HPI score of 49 out of 100 reflects the fact that humanity as a whole has much to change..." Remember those nonsense days of yesteryear when a HPI of 49 used to be considered good? Now look how far we've come! Also of note-- by their index, China's doing nearly twice as much towards the end of a "happy planet" than North America. Just consider that sentence for a little bit.
Figure 6 in the report is a scatterplot of happy life years vs. GDP per capita, by country.
