The 1 in 150 prevalence of autism found in the 1st multi-state CDC study was found in individuals born in 1992 (ADDMN, 2007).

A 1 in 86 prevlance of autism was found in the UK in individuals born in 1990 and 1991 (Baird et al., 2006). Using different ascertainment methods, approximately a 1 in 175 prevalence of autism was found in the same cohort in an earlier study (Baird et al., 2000). That is, using different ascertainment methods (but the same diagnostic criteria, and overlapping instruments) doubled the apparent prevalence of autism within the same cohort.
