From January 28 - February 1, 2017, YouGov asked 7,150 adults living in the United States the question:
"Do you consider the countries listed below to be a friend or an enemy of the United States?"
Each respondent was asked his or her opinion about a random selection of 15 of 144 countries. The response options were "Ally", "Friendly", "Unfriendly", "Enemy" or "Not Sure" for each country listed. The selection of the 144 countries was non-scientific, but the sample accounts for the majority of non-island countries in each continent (excluding Antarctica) and the vast majority of the world's population. Certain states included have disputed statuses, such as the State of Palestine and Kosovo, but given their particular histories vis-à-vis the U.S., they have been treated as distinct.
The 144 countries were divided into three groups of 48 based on the percent of people in the 2013-2014 surveys who responded "Not sure". Each respondent was shown 9 countries from the most well known group, 4 countries from the midddle group, and 2 countries from the least well known group. Countries from the most well known group were rated by 1259-1399 respondents. Countries from the middle group were rated by 530-633 respondents. Countries in the least well known group were rated by 251-341 respondents.
