Age 6 to 11 years corresponds to birth years 1999 to 2004, age 11 years to birth year 1999. Estimates have been calculated by using NPR case numbers from 2010, assuming that within that calendar year, the NPR has captured 60% of all diagnosed cases of ASD, ADHD, and epilepsy and 85% of diagnosed cases of CP.
