"HAMILTON: ... parents' age and race had a relatively small effect, but the effect of education was huge. In most areas, a child whose parents completed college was four times as likely to be diagnosed with autism as a child whose parents did not finish high school.
Dr. HERTZ-PICCIOTTO: It doesn't necessarily mean that higher education causes autism, but that it gets you the diagnosis more frequently.
HAMILTON: Hertz-Picciotto says that's partly because educated parents are more likely to request services for children with autism.
Dr. HERTZ-PICCIOTTO: It may also have to do with people with more education are just better able to navigate a very complicated and possibly arcane health system.
HAMILTON: But she says parents weren't the only factor affecting diagnosis rates.
Dr. HERTZ-PICCIOTTO: A couple of the clusters were found actually fairly close to a treatment center in California."
So if you are geographically close to a specialty treatment center and educated, you're in a "cluster". As Dr Desert Flower used to do autism research, this subject has a place near and dear to our hearts.
