The epidemiology of autism is the study of the incidence and distribution of autism spectrum disorders (ASD). A 2022 systematic review of global prevalence of autism spectrum disorders found a median prevalence of 1% in children in studies published from 2012 to 2021, with a trend of increasing prevalence over time.
The estimated prevalence of autism is 11.8 per 10,000 people while the estimated prevalence of autism spectrum conditions is 26.6 per 10,000 people. In Japan, recent estimates of autism spectrum are as high as 13 per 10,000 people. This suggests that autism is more common in Asia than previously thought.
Rates of autism are poorly understood in many low- and middle-income countries, which affects the accuracy of global ASD prevalence estimates, [374] but it is thought that most autistic people live in low- and middle-income countries.
Autism spectrum disorder spiked 175% among people in the U.S. from 2.3 per 1,000 in 2011 to 6.3 per 1,000 in 2022, researchers found. ... Experts not involved in the study said the research ...
The American sociologist Gil Eyal, following a comparison of epidemiological data on autism in 17 industrialized countries between 1966 and 2001—carried out by Éric Fombonne [40] —found that the prevalence of autism in France is the lowest of these countries. [41]
Current studies show that autism has a prevalence rate of around 1% among the Chinese population. Though there is evidence that, this number may be more significant due to under-diagnosis and lack of awareness among many in China. In China, autism was first recognized as a neurological disability in 2006. The country has passed a number of laws ...
At a 2013 conference for the parents of children with autism, an audience member asked Kennedy a question about the CDC and autism (some of the question is inaudible in a low-quality recording of ...
Sex and gender differences in autism exist regarding prevalence, presentation, and diagnosis. Men and boys are more frequently diagnosed with autism than women and girls. It is debated whether this is due to a sex difference in rates of autism spectrum disorders (ASD) or whether females are underdiagnosed.
