This table shows an analysis of the prevalence of mental retardation or developmental disabilities among non-institutionalized persons ages birth to 5 years. The estimated prevalence is much lower among children ages birth to two years than for children ages 3-5 years. Although the same criteria were used for both groups, fewer questions were available for the youngest children in the NHIS-D to identify them as having ID/DD. Amongst the youngest children, the estimated prevalence was substantially higher in the Northeast than in the Midwest. Children ages 3-5 in the Midwest also had lower than average estimated prevalence rates.
