To determine the countries that hate America most, 24/7 Wall St. relied data from The U.S.-Global Leadership Project, a partnership between Gallup and the Meridian International Center. Gallup also provided data from a number of other indices it produced through polling in 2011. Additional economic information came from the International Monetary Fund (IMF), and data are for the most recently available year. IMF figures on GDP per capita are given at purchasing-power-parity in order to show real differences in wealth. Life expectancy comes from the World Bank and is for the most recently available year.
