CDC autism identification rose from about 1 in 150 children in 2000 to 1 in 31 in 2022
Source: CDC Data and Statistics on Autism Spectrum Disorder, ADDM Network combined estimates for 8-year-old children.
Method: I charted CDC identified prevalence estimates from 2000 to 2022. The 4.8x figure is 32.2 per 1,000 children in 2022 divided by 6.7 per 1,000 children in 2000.

Important limitation: this is identified prevalence, not a simple count of how many autistic children exist. It can reflect diagnosis, screening, records, awareness, access, and underlying prevalence.
