If you listen to anti-vaccine influencers, they would have you believe that there were no autistic kids or adults in the 1970s.

It is the cornerstone of their ‘evidence’ that vaccines are associated with autism.
Where Were the Autistic Kids and Adults in the 1970s?
Of course, there is a very good reason why we didn’t see many autistic kids in school back in those days.
Not surprisingly, it has nothing to do with their implication that there were no autistic kids!
It’s true, they weren’t in public schools.

Remember, it wasn’t until state and federal laws were passed, specifically the Education for All Handicapped Children Act in 1975, that these children started going to public school.

And even then, it took passage of the Individuals with Disabilities Act (IDEA), in 1990, which included autism as a separate disability, to make it a little easier to get services for autistic children.
“In 1970, only one in five students with disabilities was educated in American schools. In 1993, fewer than 7% of school-aged children with developmental disabilities were educated in general education classrooms. The struggle had shifted over the years from getting children with disabilities into public schools to supporting them to learn in the classrooms of neighborhood schools.”

Not easy enough though…
In 1997, IDEA was amended, with emphasis on access to the general curriculum. And giving states the authority to expand the “developmental delay” definition to also include students up to age nine.

So where were all of these autistic kids – and adults, before they got to go to public school?
Most were in state institutions.
Specifically, they were in the kind of state institutions that RFK Jr said that they wouldn’t be found in.
“In 1965, my father toured Willowbrook on Staten Island and launched the national campaign to shut down these medieval warehouses for human beings. I worked for 200 hours in one of those nightmare facilities—Wassaic Home for the Retarded in Dutchess County, New York in 1968 and 1969. I worked around people suffering every kind of intellectual disability, Down syndrome, cerebral palsy, schizophrenia and hydrocephaly, among many others. I never saw a case of autism. In fact, like most Americans, I knew nothing about the disease until I saw the extremely mild form depicted by Dustin Hoffman in the film Rainman in 1988.”
RFK Jr – Is the Autism Epidemic Real?
Remember, nearly all parents of an autistic child were told to put them in an institution back then.
“At the time, treatment for autism was very limited. Most of these children were placed in institutions, far from the public eye, to live out their lives.”
Historical Perspective
And even more of the children and adults in these institutions likely had autism but were diagnosed instead with mental retardation, intellectual disability, or childhood schizophrenia, or another disorder.
At least they were until those kinds of institutions all closed…
“The closure of institutions for ‘mental defectives’ and the growth of parental advocacy groups help to explain the increase in cases of autism since the 1960s… ‘Autism’ appropriated new meanings and this meant that it came to be more easily diagnosed in children who previously would not have been considered to display that particular thought abnormality.”
How autism became autism
Then, thanks to the push from parental advocacy groups, these children were finally able to get support in public schools.
And as more autistic kids got support in public schools, it helped raise awareness and got even more kids diagnosed with autism, especially as the diagnostic criteria in DSM was broadened.
“If conformity was king in the classroom of the mid-20th century, then students on the spectrum faced particular challenges. Their autism unrecognized, they were sometimes regarded as willfully nonconformist, disruptive, or emotionally unstable. Some managed to earn stellar grades, while others muddled along academically, sometimes in special education classes, sometimes not. “…These are the lost generation: those who today would receive their diagnosis by 6 or 8 years old, if they were a 21st century child,” according to British researchers.”
A Lost Generation: Growing Up With Autism Before The “Epidemic”
Still, it is important to understand that even more children and adults at that time had undiagnosed autism…
This is the “lost generation” of children and adults with autism that are hopefully getting diagnosed now, as an older adult, as awareness has so greatly increased.
“Fast forward to the year 2006, when the American academy of pediatrics would finally starting to recommend screening all children for autism in pediatric visits at 18 and 24 months. Which is great, however, Autistics born after 2005 (the year I graduated high school) would miss out on the assessments.
I’m going to be 36 next week, and was already a legal adult when they started these childhood screenings, which are great for future generations, but did NOTHING for Autistics like me and the many others who were missed or ignored (completely) by the American medical system.”
The Missing Generations of Autistic People
This is the autism story that anti-vaccine influencers don’t want you to know, because it doesn’t mesh with their world view that vaccines triggered an autism epidemic in 1989.
But now, the next time they mention Rain Man or that they didn’t go to school with any autistic kids, you will be ready to refute their misinformation! And you will be able to explain how we are mostly seeing an increase in kids getting diagnosed with autism, not in more kids having autism.
