With so many questions still unanswered and so little scientific information translated from English into other languages we are in the dark about how people across the globe view autism.

The World Autism Views Project aims to give a voice to people everywhere so researchers can design appropriate programs for children with autism. The survey is available in over 20 languages and is anonymous. The results will be available by May 1st on an interactive map.

See from where in the world people are responding; take a look at the World Views Project Map.

World Autism Map

Very few epidemiological studies, published in international peer-reviewed research journals, have measured autism prevalence rates outside the western world.

Autism Prevalence Rates by Country

Although you might think that there have been hundreds or even thousands of studies conducted, there are relatively few.

Growth in Study Population Numbers and Autism Rates

You may have heard much said about increasing rates of autism. You might have for example heard statistics such as 1 in 100 children or 1 in 80 boys. The studies that have been conducted to determine these statistics vary widely with study populations ranging from as few as 826 subjects to as many as 4,950,000 subjects and frequencies of autism from 0.70 children in 10,000 to 72.60 children in 10,000 (that’s 1 in 138).

The studies also vary significantly in what is referred to as a confidence interval, the range of values that may indeed be correct. For example, a study that reports a number of 30.80 in 10,000 would indicate that the number may be as low as 22.9 or as high as 40.9.

The chart below takes the data from 44 studies conducted from 1966 to 2010 and presents a cumulative view of the data by country. By country, we accumulate the number of people studied and the number of cases of autism determined. We divide latter by the former to determine a cumulative rate.

Thank You!

Thousands of people around the world completed the World Autism Views 2011 survey which closed on April 16, 2011.

Our researchers are currently processing all the data and will be posting results over the coming weeks.

Thank you for your support and participation in the Autism World Views project.
