I was curious about the fact that Arizona and Hawaii data was excluded from the study and so I sent an email to my friend Bill Grant asking some questions. He responded by clarifying that only African American data were excluded because of the small numbers.

He also stated (as I expected) that AZ was lower in autism prevalence for all populations. Thus, the premise that adequate UVR/vitamin D levels is "preventative" for autism is supported.

This is important because a recent CDC report stated that "As of 2012, one in 50 kids between the ages of 6 and 17 has some form of autism, compared with one in 88 only five years earlier."
