New figures from the Centers for Disease Control show 1 in 68 children is being diagnosed with an autism spectrum disorder in the United States. That's about a 30 percent increase from two years ago.
The report also finds that autism is almost five times more common among boys than girls. While the disorder can be diagnosed as early as age 2, most children aren't diagnosed until age 4.
According to the CDC report, Albama has the lowest prevalence of autism with one in 175 children diagnosed with the disorder. New Jersey has the highest prevalence with one in 45 diagnosed with autism.
Researchers say the disparity could be due to different reporting methods used
