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.
Autism occurs in as many as one or two per 1,000 children.
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.
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
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.

Cumulative incidence is a measure of frequency, as in epidemiology where it is a measure of disease frequency during a period of time. Cumulative incidence is the incidence calculated using a period of time during which all of the individuals in the population are considered to be at risk for the outcome. It is sometimes referred to as the incidence proportion or the attack rate. Cumulative incidence is calculated by the number of new cases during a period divided by the number of people at risk in the population at the beginning of the study.
