Curiously, of the people who answered “yes” to being vegan, most had said "no" when asked if they considered themselves to be a vegetarian, suggesting vegans view themselves as different from vegetarians, rather than a type of vegetarian.
Overall, there was virtually no change in the number of people who considered themselves to be vegetarian from the last poll in 1999, when 6% of the population labeled themselves as such.
The most notable result of the study found that unmarried adults were more than twice as likely to be vegetarian over married adults. Also, there were slightly more female vegetarians than male, and more older vegetarians than younger adults, but the differences were not substantial.
The survey, conducted via phone, polled 1,014 U.S. adults. This was the first time that a Gallup poll asked respondents if they were vegan.
