Denmark

Denmark's GDP is good- not as much as America's some-odd trillion, but enough for their prosperous small country. Their Human Development Index number is very good- one of the best in the world, meaning they have good education, great mental and physical health, and overall a satisfying lifestyle. Their life expectancy, in turn, is good, at 81 on average between females and males. Women there are pretty well educated, only about a year less than women in the United States. Their population is almost stable, with 1.7 births per woman. Since it isn't two children per woman, their population is slowly declining as of now, and the urbanization is a decent rate.

Two things that have interested me, found on Gapminder, are the environment and society aspects of the country. When looking at the worldwide annual CO2 emissions, Denmark emits a very small amount, roughly 37,000 tonnes, as opposed to the giants of carbon emission, China and America, who emit 9,628,000 tonnes and 5,122,000 respectively. Also charted on this graph are the life expectancy of each country in relation to their carbon emissions. Denmark's is 80, one higher than the U.S, and four years higher than China. 

Next, I looked at military expenditures, charted also with life expectancy (since money not funding the military usually goes to programs benefiting people and their health). Denmark spends 5.58 million, with a life expectancy of 80, while China spends 1.35 billion and the United States spends 312 million. While the life expectancy differences are much, these studies show correlations that increase human happiness/well being.
