100,000? 0.4% of the total population.
just look at the life expectancy: 76-78 years for male, 84-86 females.
I dont have a % for women older than 78 but it could almost compete with 0.4%. Not to mention life expectancy of aboriginal men being in the 60's i think (aboriginals are now around the 500,000 mark of our population).
Also need to take into account the number of lesbians, which may or may not compete with the number of gay males. and also cat ladys, but wont have a % figure on that.
