The prevalence of child autism in the United States is higher than previously estimated, revealed a new report released today by the Centers for Disease Control and Prevention (CDC). According to the recent findings, one in every 69 eight-year-old American children is living with an autism spectrum disorder.
This latest survey is based on data collected in 2014 that estimated the number of autism spectrum disorder (ASD) cases among more than 300,000 children from 11 states across the nation, states CNN.
The figures show a raise in autism prevalence rate, which has increased to 1.7 percent compared with the previous estimate of just 1.5 percent (one in 68 children) detailed in the 2016 report, which covered data from 2010.
"For 2014, the overall prevalence of autism spectrum disorder among the 11 (autism monitoring) sites was 16.8 per 1,000 (one in 59) children aged 8 years," the researchers wrote in the report.
The CDC points out that these numbers are not nationally representative, but simply reflect a detailed look at autism in these specific communities.
The 11 states included in the report are Arizona, Arkansas, Colorado, Georgia, Maryland, Minnesota, Missouri, New Jersey, North Carolina, Tennessee, and Wisconsin. In 2014, these states comprised eight percent of all U.S. 8-year-olds, revealed the CDC's Autism and Developmental Disabilities Monitoring (ADDM) Network.
The percentages of autism prevalence among 8-year-olds in each state ranged from 1.3 percent of children in Arkansas to as much as 2.9 percent in New Jersey, NBC News reports.
