Vegetarianism is the practice of abstaining from the consumption of meat (red meat, poultry, seafood, and the flesh of any other animal). Vegetarianism may be adopted for various reasons. Objections to eating meat might arise out of concerns for animal welfare, animal rights, or be borne out of religious beliefs. Other motivations for vegetarianism include health-related, environmental, cultural, aesthetic or economic ones.

There are different types of vegetarianism: an ovo-lacto vegetarian diet includes both eggs and dairy products, an ovo-vegetarian diet includes eggs but not dairy products, and a lacto-vegetarian diet includes dairy. By contrast, the vegan diet excludes all animal products, including eggs and dairy.

In a 2019 national survey of 2,027 U.S. adults aged 18 and older, commissioned by the Vegetarian Resource Group, 4% of respondents self-reported as vegetarian (or vegan).

In a major poll of adults in the U.S. done in 2028, what percentage will self-report to follow any vegetarian diet (including a vegan diet)?

Resolution

For the purpose of this question, self-reporting any vegetarian status amounts to agreeing with the proposition "I never eat meat, fish, seafood, or poultry". At least 2,000 adults representing a cross section of U.S. adults must be polled. The preferred source is a poll commissioned by the Vegetarian Resource Group (VRG). If surveys commissioned by the Vegetarian Resource Group are no longer admissible or are discontinued, an admin may decide to consult another poll if i) it surveys a representable cross section of U.S. adults, and ii) at least 2,000 adults are polled, and iii) respondents are asked whether they never eat meat, fish, seafood or poultry. If multiple polls are considered credible by an admin, the admin may choose to resolve as the median percentage of each poll.
