It doesn’t actually matter, because the statistics of normal man are worse.
One study of over 4,000 Americans found one in five have fantasized with having sex with an animal at least once. I can't find the contents of said survey so I cant verify the data or method of questioning myself.
The Kinsey study reports 4-8% of men have performed zoophilic acts, and that number climbs to 55% for those living on a farm. Said survey was questioned for poor sampling that included a high percentage of mental patients, tainting the results.
The recently posted survey reported that about 50% of responders noted some sexual attraction to animals; though it trended low on the ranking scale. The study also noted a few limitations:
1)since there is no way to gain a truly randomized selection of furries it is impossible to determine if it is an accurate representation of the fandom. It was advertised on various furry sites and also spread though word of mouth. This could have impacted the results as the survey was shared among individuals in similar communities.
2) their survey did not assess alternative reasons for being a furry; the survey was meant to study male furry sexuality and was heavily advertised as such. This could be an explanation for why sexuality is so disproportionately represented in this survey compared to others
What does this tell us? Hard numbers on zoophilia are hard to come by, and most surveys performed on the subject have had issues with unbiased sampling.
Taking the numbers at face value:
20% of Americans report some level of sexual fantasy regarding animals
8% of men have performed sexual acts on an animal, raising to 50% of men living on farms.
I found no statistics on furries that have actually committed the act.
