Overview
Epidemiology and Demographics
The prevalence is 1% in the general population, with 6 per 1000 persons having a severe mental disability. During 2014–2016, the prevalence of children ever diagnosed with any developmental disability significantly increased, from 5.76% in 2014 to 6.99% in 2016 while the prevalence of children ever diagnosed with intellectual disability did not significantly change from 2014 to 2016. [1]
Age
The prevalence of intellectual disability was lower among younger children than older children: 0.73% among children aged 3–7 years, 1.45% among children aged 8–12 years, and 1.40% among children aged 13–17 years. [2]

The prevalence of children diagnosed with intellectual disability did not differ significantly by race and Hispanic ethnicity. The difference in the prevalence of intellectual disability between non-Hispanic black children (1.53%) and non-Hispanic other children (0.86%) was not statistically significant (p = 0.21). [3]
