Over that time, there were about 5 million births and more than 12,000 autism cases.
The results:
Women over age 40 are 77% more likely than women under age 25 to have a child with autism.
Women over age 40 are 51% more likely than women aged 25-29 to have a child with autism.
Women aged 35-39 are 31% more likely than women aged 25-29 to have a child with autism.
Women aged 30-34 are 12% more likely than women aged 25-29 to have a child with autism.
Women under age 25 are 14% less likely than women aged 25-29 to have a child with autism.
Men over age 40 are twice as likely as men under age 25-29 to have a child with autism, but only if the mother is under age 25.
