Apparent new rise in autism may not reflect true prevalence

This article discusses research on the prevalence of autism in the US. The latest research found that the prevalence rose from 1 in 91 children in 2009 to 1 in 40 in 2017. The authors of the research suggested that a  sizable portion of the increase in autism is probably due to rising awareness of the condition and improved systems for identifying autistic children. Health care experts expressed concern that people may view the numbers as reflecting a true increase in prevalence, rather than largely influenced by improved detection of autism.
