Well since the earth's population has more than doubled since 1950, I'm sure the population of Aspies has increased. The real question is, how does the ratio of Aspie-NT births change from 1950-2012.
I don't know Deno but I meant to say I do not think the ratio of aspies to NTs has changed. I believe it is genetic and environmental determinants of ASD are not significant.
