In 2014, 2.24 kids were been diagnosed with autism spectrum disorder compared to 1.25 in the 2011-13 survey, indicating a steady rise in the number of autistic kids.
The reason the latest numbers for autism have climbed sharply is because of a simple change in questions asked from the interviewees. In the new survey, more than 10,000 families were interview and asked directly whether their kids have been diagnosed with autism. Previously, different conditions from anemia to autism were listed and parents were asked if their kid had been diagnosed with any of them.
Though the latest survey is done in a new way, experts say it is probably the most accurate estimate yet.
"One in 45 is what we think is the most accurate parental report of autism to date,” said Benjamin Zablotsky, an epidemiologist at the National Center for Health Statistics and lead author of the report.
“I think within this report we found that the way that we ask the parents about autism spectrum disorder can have an impact on the way the parents respond to the question.”
In contrast the prevalence of other developmental disorders have declined significantly from 4.84 percent in 2011-13 to 3.57 percent in 2014, suggesting people might have switched their answers from other developmental delay to autism in 2014 survey.
Every year, the number if kids diagnosed with autism goes up. Previously, it was 1 in 68 kids but now it is 1 of 45 in children aged from 3 to 17.
