1. Background.

Despite the impression given by the media, the actual number of homosexuals is quite small. Essentially all surveys show the number of homosexuals to be only 1-3% of the population. The number of homosexuals living in 'common law partnerships' is even less, only 0.5% of all couples. This contrasts with 70% of all households with a married couple.

The pressure for introducing same-sex marriages comes from a very small section of society.

. According to Statistics Canada, 1.3% of men and 0.7% of women considered themselves to be homosexual.


. Recent studies in many different countries show that the prevalence of homosexuality is less than 3% of the population: In a US study, the prevalence of homosexuality was estimated to be 2.1% of men and 1.5% of women. (Gilman SE.Am J Public Health. 2001; 91: 933-9.) Another US study estimated the prevalence of the adult lesbian population to be 1.87%
(Aaron DJ et al. J Epidemiol Community Health. 2003; 57 :207-9.)

In a recent British survey, 2.8% of men were classified as homosexuals (Mercer CH et al. AIDS. 2004; 18: 1453-8). In a recent Dutch study 2.8% of men and 1.4% women had had samesex partners. (Sandfort TG et al. Arch Gen Psychiatry. 2001; 58 :85-91.) In a New Zealand study, 2.8% of young adults were classified as homosexual or bisexual. (Fergusson DM et al. Arch Gen Psychiatry. 1999; 56 : 876-80)

. The number of homosexuals in essentially all surveys is less than 3%. (Statistics Canada found only 1% of the population who described themselves as homosexual.) However, the percentage of homosexuals among pedophiles is 25%. (Blanchard R et al.Fraternal birth order and sexual orientation in pedophiles. Archives of Sexual Behavior 2000; 29: 463-78.)

Therefore, the prevalence of pedophilia among homosexuals is about 10-25 times higher than one would expect if the proportion of pedophiles were evenly distributed within the (hetero- and homosexual) populations.
