About one in 88 children has been identified with an autism spectrum disorder (ASD) according to estimates from CDC’s Autism and Developmental Disabilities Monitoring (ADDM) Network.  test

ASD’s are reported to occur in all racial, ethnic, and socioeconomic groups.

ASD’s are almost five times more common among boys (1 in 54) than among girls (1 in 252).

Studies in Asia, Europe, and North America have identified individuals with an ASD with an average prevalence of about 1%.  A recent study in South Korea reported a prevalence of 2.6%.

About one in 6 children in the U.S. had a developmental disability in 2006-2008, ranging from mild disabilities such as speech and language impairments to serious developmental disabilities, such as intellectual disabilities, cerebral palsy, and autism.

This Video is done by Autism Speaks which is another Non-Profit Charity. Their specialty is stuff like this, National Speaking. Someone needs to speak up. We want our specialty to be helping the families with Autism. I did have to go back several pages in You Tube because of all the videos concerning MMR Vaccine and some cover-up by the CDC on the subject. I don’t know about that, but you can look it up yourself. 


Studies have shown that among identical twins, if one child has an ASD, then the other will be affected about 36-95% of the time. In non-identical twins, if one child has an ASD, then the other is affected about 0-31% of the time.

Parents who have a child with an ASD have a 2-18% chance of having a second child who is also affected.

ASDs tend to occur more often in people who have certain genetic or chromosomal conditions.  About 10% of children with autism are also identified as having Down syndrome, fragile X syndrome, tubers sclerosis, and other genetic and chromosomal disorders.

The majority (62%) of children the ADDM Network identified as having ASDs did not have intellectual disability.

Children born to older parents are at a higher risk for ASDs.

A small percentage of children who are born prematurely or with low birth weight are at greater risk for having ASDs.

ASD commonly co-occurs with other developmental, psychiatric, neurologic, chromosomal and genetic diagnoses.  The co-occurrence of one or more non-ASD developmental diagnoses is 83%.  The co-occurrence of one or more psychiatric diagnoses is 10%.

Research has shown that a diagnosis of autism at age 2 can be reliable, valid and stable.

More children are being diagnosed at earlier ages – a growing number (18%) of them by age 3.  Still, most children are not diagnosed until after they reach age 4. Diagnosis is a bit earlier for children with autistic disorder (4 years) than for children with the more broadly-defined autism spectrum diagnoses (4 years, 5 months) and diagnosis is much later for children with Asperger Disorder (6 years, 3 months).

Studies have shown that parents of children with ASDs notice a developmental problem before their child’s first birthday. Concerns about vision and hearing were more often reported in the first year, and differences in social, communication, and fine motor skills were evident from 6 months of age.


Individuals with an ASD had average medical expenditures that exceeded those without an ASD by $4,110-$6,200 per year.  On average, medical expenditures for individuals with an ASD were 4.1 – 6.2 times greater than for those without an ASD.  Differences in median expenditures ranged from $2,240 to $3,360 per year, with median expenditures 8.4 – 9.5 times greater.

In 2005, the average annual medical costs for Medicaid-enrolled children with an ASD were $10,709 per child, which was about six times higher than costs for children without an ASD ($1,812).

In addition to medical costs, intensive behavioral interventions for children with ASDs cost $40,000 to $60,000 per child per year.

Here is another fact from The Census Bureau.  In 2007 population in the USA leveled off to zero growth from new babies. They mentioned that in 1909 there were 127 babies per thousand women. In 1960 there were 118 babies born per thousand women. In 2007 there were 69.3 babies born per thousand women. Finally in 2012 there were 63 babies born per thousand women, which is way below the 2007 level.

I have conducted personal interviews with several women in the child bearing years asking if the prevalence of Autism and other problems has helped make their mind up about having more or first children. You would not be surprised to hear that this was a major thought on their mind about making or adding to a family.

Okay, okay, okay, so how did all this work on this web page get started? I was talking to someone I know, who it Autistic and his name is Matt L. about how many Autistic people there were in the USA. We argued quite a bit but both had to give up because neither of us knew but we agreed it must be in the millions.

You have to know I am only a carpenter and not a math major at U of M in Ann Arbor (not far away). Here is what I figured. In the back of my head I remember the population of the USA is about 360,000,000. About half are women, or 180,000,000. Using the before mentioned birth rate of averaging at about 65 per thousand that would be 180,000 groups of 1000 times 65 births or 11,700,000 babies born per year and if one in 88 were autistic that would be 11700000 / 88  =  132,955 Autistic babies per year. Now to get to the answer Matt L and I were talking about you would have to multiply by at least 20 for the last 20 years, a total of 2,659,090 Autistic people in the USA now. That would be wrong because my son is over 30 years old so times 30 would be 3,988,636 people with Autism in the USA. Again, who is right? Me or Matt L., Who knows? If there is a real statistic person out there and wants to volunteer an investigation to get a more precise number, I am sure it can be done. Each year would have to be done individually for at least 30 years. So when did the new wave of autism really start? Was it in full swing right from the start or kind of gradually work its way up to 88 per thousand? The population changed every year so how much?  There are lots of things to take into account. If someone does this please send it in, along with the figures you used to the e-mail or regular mail address. Thanks

There is more work for academia also. With this number, how much did it cost extra per person? How much extra in total?  Also another item, This is everywhere in the world. What would be the numbers for the world?

I would like to thank Elizabeth C., a data mining expert at the The Shelby Township Library for digging up all the CDC data. She is our first volunteer.
