> Robert F. Kennedy junior, America’s health secretary, thinks that autism has become an “epidemic” in his country. His concern stems from figures from the Centres for Disease Control and Prevention, which shows that the condition now affects 32 per 1,000 eight-year-old children in America (see chart). That is in contrast, he says, with the near-absence of the condition in his childhood. Mr Kennedy was born in the 1950s, and studies estimate a prevalence of autism to around two to four per 10,000 in the 1960s.
I'd note that RFK Jr.'s very own aunt was lobotomized then hidden away for something that sounds a lot like autism if diagnosed today. https://en.wikipedia.org/wiki/Rosemary_Kennedy
