Someone I know has spoken to a dozen senior researchers and others in EA animal welfare.
The resulting understanding is that the actual number of vegans or vegetarians are consistent with the numbers in the above comment (1-2% in the USA, UK and CAD).
Another important fact seems to be that these numbers have not changed despite decades of dietary change information and campaigning at the individual, consumer level.
This seems to be relevant when making plans in animal welfare about which interventions to pursue.
