Have you ever noticed that it is hard for people (at least in the United States) to talk about autism without mentioning the statistics? Does this phenomenon occur regularly in other countries? Canada? Enland? Brazil?
Here in the United states, the most relied on statistics come from the Centers from Disease Control (CDC). Many sites, including the one from the Autism Society of America, quote the CDC. Here is the probably the most quoted CDC stat: "[The] CDC’s Autism and Developmental Disabilities Monitoring (ADDM) Network released data in 2007that found about 1 in 150 8-year-old children in multiple areas of the United States had an ASD."
I just visited the CDC website and found much more than I was expecting. I, a newbie to the autism blogosphere, learned (and I realize that many of you already knew) about the history of autism stats, the difference between the words "incidence" and "prevelance," and all about the CDC's Autism and Developmental Disabilities Monitoring (ADDM) Network, which I did not know existed. I'd explain some of this, but the CDC does it better.
I am glad I took the time to read some of the original content. I would recommend the CDC's website for beginners as well as for those who just want to learn more about autism. With autism, there is always more to learn...
