Yes, by numbers
A recent report from the centers for disease control (cdc) estimated ASD at 1 in 88 live births, the highest estimate yet.
This contrasts with estimates from 20 years ago of 5-10 in 10, 000. What is unclear is why this has changed so much. Some believe it mostly is because of changing definitions and increased recognition of the problem; others insist it is a true change. Time will tell.
