Determining an accurate autism prevalence rate has proven difficult. As autism rates have climbed (the most recent data from the CDC shows 1 in 150 children in the US are on the spectrum), so has the desire to provide researchers and the public with the most accurate prevalence rate. A new study, conducted in part by noted autism expert Professor Simon Baron-Cohen, shows that in the United Kingdom, 1 in 64 children is on the autism spectrum.
The results showed that, when the undiagnosed cases were included, one in 64 children had the condition, equivalent to 1.5 per cent of the population. Extrapolating them to the whole population raised the total number of children affected from 500,000 to 750,000. For every three cases that are diagnosed, a further two may be undiagnosed, the researchers concluded.
