Current diagnosis rate is 1 in 68 children in the US.
Further statistics are harder to find, there's also question as to how correct the above statistic is. In theory Autism is under-diagnosed due to cultural and social factors such as stigma preventing parents seeking diagnosis, people avoiding diagnosis to avoid discrimination, and poverty preventing access to diagnosis. As it is we don't really know what the true rate of Autism is.
There is a higher incidence of autism among boys than girls. Since the new vaccine was approved, the incidence of the disease has decreased significantly.
Relative risk (RR) can be calculated by comparing the incidence rates of an event occurring in two groups. First, determine the incidence rate in the exposed group (e.g., those with a risk factor) and the incidence rate in the unexposed group (e.g., those without the risk factor). Then, divide the incidence rate of the exposed group by the incidence rate of the unexposed group (RR = Incidence Rate in Exposed / Incidence Rate in Unexposed). A RR greater than 1 indicates increased risk, while a RR less than 1 indicates decreased risk.
The unemployment rate among college graduates affected by autism is 85.
Attack rate is the proportion of exposed that become ill. Incidence rate is the number of new cases that become ill over a certain period of time.
prevalencerefers to the number of cases of disease thatexistsin a population and the incidence refers to the number of new cases of diseaseoccurringin a population.
In the 1970’s the incidence of autism was 2-3 per 10,000. Today, according to the Center for Disease Control (CDC), the estimated prevalence of autism spectrum disorder in the U.S. is 1 in 88 children.
398,538
The concordance rate for autism in identical twins is estimated to be around 70-90%, while in fraternal twins it is around 0-30%. This suggests a strong genetic component in the development of autism.
Incidence rates vary between 25 and 50 per 100,000 persons.
The different forms of autism are thought to overlap considerably. But the fact that there is wide variation in symptoms among children with autism led to the concept of autism spectrum disorder. Autism seems to be on the rise, and autism spectrum disorders affect between two and six children out of every 1,000 in the U.S. It's unclear, though, whether the growing incidence of autism represents a real increase or just improved detection
It's relative. It depends on your opinion about what constitutes a high rate. The vast majority of people do not have autism or Asperger's Syndrome. It occurs in less than 1% of the population. There is a higher rate of cerebral palsy, but a lower rate of multiple sclerosis.
