Global Autism Prevalence Map by Spectrum
Spectrum is proud to debut the first-ever global map of autism prevalence.
The interactive map provides a clear look at the distribution of studies on autism prevalence over time and space. It highlights the places for which prevalence data are available — or missing. We update the map and fill in the gaps as the data become available.
The number of people diagnosed with autism worldwide has risen dramatically over the past few decades. Prevalence estimates in different countries vary widely, as these estimates depend in large part on how scientists collected the data.
You can filter the studies using various relevant criteria, download the data and analyze it yourself.
