2008: 7.3 Million Americans Are Vegetarian
22.8 million follow a vegetarian diet.

EL SEGUNDO, Calif. -- The just-released "Vegetarianism in America" study, published by Vegetarian Times, shows that 3.2 percent of U.S. adults, or 7.3 million people, follow a vegetarian-based diet. Approximately 0.5 percent, or 1 million, of those are vegans, who consume no animal products at all. In addition, 10 percent of U.S., adults, or 22.8 million people, say they largely follow a vegetarian-inclined diet.

Data for this survey were collected by the Harris Interactive Service Bureau on behalf of Vegetarian Times. The poll surveyed 5,050 respondents, a statistically representative sample of the total U.S. population. Vegetarian Times commissioned RRC Associates, a research firm in Boulder, Colo., to perform the data analysis.

The 2008 study also indicates that of the non-vegetarians surveyed 5.2 percent, or 11.9 million people, are "definitely interested" in following a vegetarian-based diet in the future.

The study also collected data on age, gender and other demographic factors. Of the vegetarians surveyed:

-- 59 percent are female; 41 percent are male.

-- 42.0 percent are age 18 to 34 years old; 40.7 percent are 35 to 54; and 17.4 percent are over 55.

-- 57.1 percent have followed a vegetarian diet for more than 10 years; 18 percent for 5 to 10 years; 10.8 percent for 2 to 5 years, 14.1 percent for less than 2 years.
