Last summer, the Vegetarian Resource Group (VRG) published a poll measuring the number of adult vegans in the United States. They’ve now conducted 12 such polls between 1994 and 2020, with the most recent one showing the highest percentage of the population as vegan (3%) which translates to the highest number of vegans to date (7.6 million). Possibly more important, there’s been a strong, steady increase in the number of vegans over the course of these polls.
More details are in our spreadsheet, VRG polls, along with a larger version of the graph. You can also read about them on the Vegetarian Resource Group’s website.
