Hi Bridget,

I was a bit off. According to wikipedia 0.25% of the population have AS with three times as many men.
So that's about 0.375% of men and 0.125% of women.

According to another website there are about 500,000,000 english speaking users of the internet. That is about 1,250,000 with AS.

Most will not be diagnosed but even if only 5% are, there would be 62,500 possible members (with AS).

I wish I hadn't raised this now!

Jon
