"Fathers who worked in engineering were two times as likely to have a child with an autism spectrum disorder (ASD).
Those who worked in finance were four times more likely and those who worked in health care occupations were six times more likely to have a child on the autism spectrum."
I haven't seen the paper, but presumably the authors used a binary definition of "technical", which I suspect actually means "job that requires higher education", which might also correlate with "job in which fathers tend to have children later".
"There was no association with a mother’s occupation. However, children who had both parents in technical fields were at a higher risk of having a more severe form of autism."
Those who worked in finance were four times more likely and those who worked in health care occupations were six times more likely to have a child on the autism spectrum."
