According a Gallup Poll, 5% of Americans consider themselves vegetarians. Believe it or not this is down from the 6% who identified themselves as vegetarians in 1999 and 2001!
According to the Poll results, almost all segments of the U.S. population have similar percentages of vegetarians, suggesting that most stereotypes of who is and is not the typical vegetarian in American society have little basis in fact.
The biggest distinction seems to come in terms of marital status. Unmarried adults are more than twice as likely as married adults to be vegetarians. Vegetarianism appears to be slightly more prevalent among women than among men, and among those who are older than among younger adults, but these are not big differences.
Gallup reports that, Vegetarianism in the U.S. remains quite uncommon and a lifestyle that is neither growing nor waning in popularity. The 5% of the adult population who consider themselves to be vegetarians is no larger than it was in previous Gallup surveys conducted in 1999 and 2001. The incidence of veganism is even smaller, at a scant 2% of the adult population.
