This Toronto Star article by Jesse Bering discusses a 2004 research study by Professor Anthony Bogaert.

“According to Brock University psychologist Anthony Bogaert, there may be more genuine asexuals out there than we realize,” the article reads. “In 2004, Bogaert analyzed survey data from more than 18,000 British residents and found that the number of people (185, or about 1 per cent) in this population who described themselves as ‘never having a sexual attraction’ was just slightly lower than those who identified as being attracted to the same sex (3 per cent). Since this discovery, a handful of academic researchers have been trying to determine whether asexuality is a true biological phenomenon or, alternatively, a slippery social label that some people may prefer to adopt and embrace.”
