U.S. Health Care vs. The World 
- Population Total: Although the U.S. population has increased by just over two percent — from 313,085,000 to 320,051,000 — it still has the third highest population among the nations cited, behind China and India.
- Gross National Income Per Capita: Singapore still leads the world in this category, and the U.S. remains second. However, the numbers for both countries have risen — and Singapore’s increase is significantly higher in comparison. The U.S. is up to $53,960 from $48,820, and Singapore has moved to $76,850 from $59,380.
- Per Capita Total Expenditure on Health: The U.S. continues to remain at the top of this category, with total expenditure on health increasing more than 7 percent, from $8,233 per person in 2013 to $8,845 in 2015.
- Life Expectancy at Birth: This category has remained stable for the top five countries, with Japan again leading with a life expectancy of 84 years, up from 83 years in 2013. Singapore, Australia, France, and Canada round out the top five for 2015, as they did in 2013 — and the U.S. remains ranked eighth with a life expectancy of 79 years for Americans.
- Immunization Coverage for 1-year-olds (Measles): The U.S. remains 12th among the nations at 91 percent, up slightly from 90 percent in 2013. The leading five nations remained the same, except for the U.K. and Mexico, which reversed in this category over the past two years. In 2013, Mexico was ranked fifth at 98 percent, but in 2015 dropped to the 13th spot at 89 percent. The U.K. now stands at 95 percent, up from 13th in 2013 at 90 percent.
- Population Using Improved Drinking Water Sources: This category was stable with the top seven countries again at 100 percent, and the U.S. remaining ranked eighth at 99 percent.
