Ozzie-Rozies, where are those numbers published?

I also found the 1 in 500 rate for India.  However, it's not dated.  Here's the link:

Hi all -

A friend of mine recently posed the question to me about what the autism rates are overseas and internationally.  I am having a hard time finding this information online (believe it or not).  Does anyone have a link or resource they can share?



I was curious about this and similarly, race /ethnicity genetics (I mean I have seen US, caucasian/ african american / latino but nothing on East or South Asians?).

In my family not having friends or being odd or poor in sports is TOTALLY fine - as long as you are good academically and most people on my Dad's side are doctors and engineers and many of them are most peculair  

I am sure my dad and a few Uncles are Aspies - 2 nephews defitniely strong quirks - one is 3 years old and not saying a word - but their ped says he is "fine" becuase he does not seem to have MR

There are a LOT of cultural influences that influence whether parents seek daignoses or not

keep in mind that there is a large cultural influence when diagnosing these things and different diagnostic tools are used in different places around the world, so the prevelence rates from countery to country would expectedly be all over the map (no pun intended).

An anthropologist, Roy Ginker has published a book Unstrange Minds that appears to be a treatise in the cultural and anthopoligical aspects of autism, it's history, etc.  It gets generally favorable reviews, though obviously not as concise as you'd probably like.

I'm with fred on this. These numbers only really reflect the number of
diagnoses, not the number of actual cases. It varies widely depending on
cultural factors.

There's *got* to be a good list out there, but I couldn't find it.  I do get the impression that the rates are fairly even for Western countries.  I remember hearing that both Sweden and Australia have both had recent studies that were pretty close to the US rate of 1 in 150.

Here are a few okay links:

Here's a list published by Lorna Wing in 1993.  It's at the bottom of the page.

Here's a list that mentions Scotland and South Africa and a couple others.

Lists various recent studies from various countries:

It is a fascinating topic!

How many kids are perceived as special, in the sense of religious mysticism, too?

And then what I suspect is the biggest cultural consideration ... poverty, education, access to health care?  Not just in India -- but also, the US and everywhere ELSE, too!

Here's something I ran across today:

"... said Dr. Edward Ritvo, professor emeritus of psychology at UCLA and a consultant with The Help Group, who saw his first autistic patient in 1953. [...]  Ritvo does not believe the Jewish community suffers a higher rate of the syndrome than the general population.  "We used to think autism was found only in certain areas or populations, but subsequently we found it everywhere: in Asia, in Africa, in blacks and whites, in rich and poor, in Jews and Mormons."


1:160 in AUSDepends on who you ask I suppose

this page suggests 1 in 100 for Australia
so does this

however like Allegra said
I have heard numbers like
1 in 150
I have even seen published higher than 1in 100

some say it's increasing
some say it ain't

and it seems to vary from state to state


Autism cases by ethnic group match more closely to percent of the population than in 1987, but still have a ways to go (presuming that autism isn't more likely in one ethnic group than another).


46.7% of population in 2000

62.01% of autism cases in 1987

43.47% of autism cases in 2003


32.4% of population in 2000

9.72% of autism cases in 1987

23.09% of autism cases in 2003


6.4% of population in 2000

15.37% of autism cases in 1987

8.98% of autism cases in 2003

Native American

0.5 of population in 2000

0.36% of autism cases in 1987

0.22% of autism cases in 2003

Asian/Pacific Islander

11.1 of population in 2000

Autism cases:

1987:  3.71% (Asian) + 0.22% (Polynesian) + 2.38% (Filipino)

2003:  7.74% (Asian) + 0.17% (Polynesian) + 2.85% (Filipino)


2.9%  of population in 2000

6.16% of autism cases in 1987

13.50% of autism cases in 2003

Comment from CA's autism report:

"Relative to the entire population of persons with autism, Asians and Hispanics increased the most in the 15-year interval between 1987 and 2002. Relative to the entire autism population in 2002, the Asian and Hispanic proportion more than doubled compared to 1987. Increased efforts on the part of regional centers over the past 15 years to reach specific ethnic groups may have contributed in part to the proportional increase in Asians and Hispanics with autism entering the system."

There was a really sad article in the LA times last month about minorities
from lower socioeconmic groups not being educated or receiving any
services for autism. It made me want to work at a community based clinic
when I get my degree.

As far as I know, Autism is prevalent in all cultures and in all ethnic groups,
it just always isn't recognized or properly diagnosed. That's a big problem
with statistics--many people are not accounted for when it comes to these
studies1 in 160 school age children is the lastest commonwealth government estimate for Australia.Liz

KajoliT.... you made a very good point in the cultural acceptance of children who are different.  Your post caught my eye because Tony's one and only friend is 1/2 Indian (Asian, not American).  His father (the Indian 1/2) does not accept that his son has any differences, and this boy is 12.  The father insists to this day it is all behavioral and a choice!  Needless to say, the mom has struggled with the issue for a long time.

I have also read the UK has a "higher" rate than the US... something like 1:90 or thereabouts.  On a side note, has anyone wondered about any connection with evaluation/diagnosis and the health care problems here in the US?  I'm talking about all the uninsured folks out there... I wonder how many families can't afford to take their kids for the evals, etc.

Scary thoughts!
