The percentage of people who are vegetarian varies by country and region. According to a recent study, 22% of the global population is vegetarian. However, a 2018 study from Economic and Political Weekly by US-based anthropologist Balmurli Natrajan and India-based economist Suraj Jacob suggests that these numbers could be inflated by social reluctance to admit to meat consumption and estimates that the percentage of vegetarians is likely closer to 20% than 30% overall, with the percentage varying by household income and caste. In the United States, 5% of adults consider themselves to be vegetarian, according to a 2018 Gallup poll. Other surveys suggest that 6% of Americans identify as vegetarian or vegan, and possibly 10 to 15 percent identify as vegetarian or vegan. The breakdown of UK responses by age shows that younger people are more likely to report being vegetarian, vegan, or pescetarian. Its important to note that these numbers may not be entirely accurate, as some people may not identify as vegetarian or vegan even if they follow a plant-based diet.
