In France only Kanner autism is well know (They must be enough handicaped to be diagnosticed autism) and their number (If I remeber the counting) is 4/10 000. Why, because France have a great retard for the autism disorder: They still believe that autism is caused be refregirator mother. The prove of what i'm saying     http://charlatans.info/autisme.shtml in this french site they claim that 4/10 000 is autism. And this is not a crappy site rulled be a isolated idiot. But if only 4/10 000 are kanner autism in france but 1/56 (thanks to autism speak) are autism and described like kanner autism. It have a huge misunderstand error in america(thank to charity organisation who use scare tactic aproved be curebie).

france believes in the refregirator mother thoery huh. didn't think they would still believe that. i wonder if other countries in europe do?

doubt if the scientific community believes that. Certain individuals probably still hold on to that thought.

not the scientific but the pshychologue comunity

I am guessing it is only certain people in that group that believe that way, in this modern time, after that theory has been pretty much disproved

Well I'm not here to debate the pshycology in france. I'm just saying that 1/56 are KANNER autism is just plain wrong. And the number of 4/10 000 of LFA is far more credible

The claimed prevalence of autism spectrum conditions in the United States isn't 1/56, it's 1/166, which Autism Speaks will commonly round to 1/150 in their commercials in order to inflate the numbers.  And they certainly do mislead people into thinking that they're all classic autism, not Asperger's syndrome or PDD-NOS.  From what I've read, the 1/166 number is generally agreed upon but there aren't good statistics on how that breaks down into the different spectrum labels.  However, while different sources that I've seen give different statistics, they all concur that the majority of people on the spectrum are not classically autistic, and the majority of those who are classically autistic are high-functioning.

I don't know how accurate the number from France is or what it reflects.  It's certainly the lowest that I've seen anywhere and could result from social pressure to not diagnose autism even if the child is LFA, considering what you've said about how autism is viewed there.  But there's no question that the number 1/56 (and, for that matter 1/150 and 1/166) in relation to Kanner autism is definitely wrong.

I will bold some parts - read or do not..just saying..here are some numbers... prevalance rates--  regarding France... see large bold...
I do not have a "modern total" later than 1993 and I cannot find anything about loower incidences in France... in fact you may have heard that ireland seems to have higher incidences but in these studies france is higher than ireland....

I will say I have learned one thing today.. and that is the Kanners is also known as infantile autism... the criteria seem more broad (some langauge delay note4d BY 3 yeras old) as opposed to regression....

here is incidence rates chart (very well researched/backed up)
Note the studies that were excluded and the silly reason why... but note that FRANCE had the higher incidence (in 1972 and 1976) AMAZING to me that studeis have been done for so many years.. also that NOS PDD was also a category even then...

The Definition and Prevalence of Autism: A Review
Lorna Wing

The Centre for Social and Communication Disorders, Elliot House, 113 Masons Hill, Bromley, Kent, BR2 9HT, UK

________________________________________________________________________________ ______________ Sixteen studies of the prevalence of autism in childhood, using epidemiological methods in defined populations in Europe, the USA and Japan, in English or with English summaries, were found in the published literature. Age specific rates varied from 3.3 to 16.0 per 10,000. Eight studies gave rates for a sub-group of 'typical' autism varying from 1.2 to 8.4. Reasons for variations were sought by examining geographic and demographic details of the populations screened, methods for initial screening and final examination of possibly autistic children, demographic and clinical details of children identified as autistic, and criteria used for diagnosis. There was evidence, independent of diagnostic criteria, of a higher prevalence among children of first generation immigrants to Europe from 'exotic' countries. Apart from this, all differences could be due to variations in diagnostic practice and increasing awareness of the manifestations of autistic conditions throughout the range of intelligence, from severely retarded to average and above. However, it remains possible, though not proven, that rates do vary over place and/or time. The problems of defining a sub-group with 'typical' autism among the wide spectrum of children with the triad of impairments of social interaction, communication aud imagination are discussed and the value of such a sub-grouping questioned. ________________________________________________________________________________ ______________

Introduction

Kanner's classic paper (1943) outlined the behaviour pattern, present from early in life, which he named 'early infantile autism'. Prior to this, there were, in the literature, occasional accounts of individual children whose behaviour fitted the picture Kanner later described; the most famous of these was Victor, the wild boy of Aveyron (see translations into English of J. M. G. Itard's reports by Lane, 1977). But, since no one prior to Kanner had published a series of such cases, no infomation exists as to the prevalence of autism before the second half of the twentieth century. Kanner (1943) described only the autistic children referred to his clinic and, later on, those attending a particular special school (Kanner, 1973). He made no estimates of the numbers in the general population, but thought that his syndrome was rare.

Twenty six years ago, Lotter (1966), working in the Medical Research Council Social Psychiatry Unit at the London Institute of Psychiatry, published the first paper to give the results of an epidemiological study of autistic conditions in a complete, large population of children of all levels of intelligence living in a defined geographical area (the former County of Middlesex, England). At about the same time, but independently, Birte Hoeg Brask (1972) was identifying children with 'childhood psychosis' in touch with psychiatric and mental retardation services in Aarhus, Denmark. Since then, there have been a number of other studies of the prevalence of autism, with varying results.

In this paper, a quarter of a century of work in this field is reviewed in order to consider possible reasons for the differences in the reported findings. The studies to be described in detail and tabulated are those meeting the following criteria; they use defined diagnostic criteria; they cover geographically defined populations; the initial selection is made from a wide range of children including those not previously diagnosed as autistic; final identification is based on clinical examinations of selected children by the authors or by the direct care clinical staff who provide information requested by the authors as part of the study. Only papers published in books or journals in English or with detailed English summaries are included, not unpublished reports.

Studies Reviewed

The results of the studies of the prevalence of autism are summarised in Tables I to S. Each is identified by the name of the area in which it was carried out. The authors of the papers, the full names of the areas studied, and the abbreviations of these names used in the tables are listed below, in the order in which they appear in the tables:

- Lotter (1966; 1967a; 1967b) Middlesex, England (Midx)
- Brask (1972) Aarhus, Denmark (Aarh)
- Wing & Gould (1979) Camberwell, London, England (Camb)
- Hoshino et al.(1982) Fukushima-ken, Japan(Fuma)
- Bohman et al. (1983) Västerbotten, Sweden(Väst)
- Cialdella & Mamelle (1989) Rhône, France(Rhôn)
- Matsuishi et al. (1987) Kurume, Japan (Kuru)
- Tanoue et al. (1988) Ibaraki, Japan (Ibar)
- Sugiyania & Abe (1989) Nagoya, Japan (Nago)
- Burd et al. (1987) North Dakota, USA (NDak)
- Ritvo et al. (1989) Utah, USA (Utah)
- Gillberg (1984) Göteborg region, Sweden (Göt1)
- Steffenburg & Gillberg (1986) Göteborg city, Sweden (Göt 2)
- Bryson et al. (1988) Nova Scotia, Canada (NoSc)
- Gillberg et al. (1991) Göteborg city, Sweden (Göt 3)
- Ishii & Takahashi (1983) Toyota, Japan (Toyo)

For the studies in Fukushima, the Rhône, and Utah, the authors gave reasons for considering that the rates found for particular age groups within the total range studied were the most accurate. The findings for these age groups are given in Tables 1 and 2. For the second and third studies in Göteborg the authors also gave rates separately for rural Bohuslän, but only the findings for city Göteborg are quoted in Tables 1 and 2. However, for all these studies, the data in Table 5 refer to all the children finally diagnosed as autistic because, for some of the papers, this was the only information given.

Exclusions

Nine studies were excluded from the tables because they did not meet the criteria listed above.

They are briefly described below.

The prevalence of autism was examined in Kyoto-fu, Gifu-ken, Toyama-ken and Hokkaido in Japan by, respectively, Haga and Miyamoto (1971), Nakai (1971), Tanino (1971) and Yamazaki et al. (1971). Only short English summaries are available for these four studies. Since diagnostic criteria are not given in the summaries the results are not included in the tables. However, from the dates of publication and the references, the diagnoses were most likely to have been based on Kanner's papers. The rates found ranged from 0.9 to 5.02 per 10,000.

One study was excluded because it was based only on inforation from computer print-outs. Treffert (1970) examined the prevalence in Wisconsin, USA among children, aged 3 through 12, seen by psychiatric or mental retardation agencies in the years 1962-67 and diagnosed as having 'Childhood schizophrenia'. He reported a total age-specific prevalence of 3.1 per 10,000 of whom 0.7 were considered to be classically autistic without any known organic cause.

Two further papers were excluded because diagnosis was based on examination of the case notes only. Aussilloux et al. (1989) studied the notes of 6-12 year old children, born 1966-73, known to the relevant services in the Hérault department, France. Using DSM-III criteria, the age-specific rates found were 4.7 per 10,000 for 'Infantile autism' and 1.8 per 10,000 for 'Childhood onset pervasive developmental disorder'. Fombonne and du Mazaubran (1992) carried out a study in four regions in France (Aquitaine, Ile de France, Lorraine and Picardie). The case notes of two annual birth cohorts of children born 1972 and 1976 respectively) known to the relevant services were examined and diagnoses made using the French system of classification (Mises, 1990). The age-specific rate for the combined categories of 'Kanner's autism' and 'Other forms of infantile autism' was 4.9 per 10,000.

The study by Steinhausen et al. (1986) was excluded because the search for children was confined to two sources only, one being the university clinic for child psychiatry and the other a centre providing a programme for autistic children. The authors used Rutter's criteria (see below) to identify children with 'nuclear' autism aged under 15 and living in West Berlin, Germany on June 1, 1992. The age-specific prevalence found was 1.9 per 10,000.

Finally, one study, by McCarthy et al. (1984), was excluded because, although the authors examined the selected children, the initial selection was made by asking child psychiatrists and the staff of relevant institutions for the names of children diagnosed as autistic. Using criteria similar to those in DSM-III (see below), the authors found an age-specific prevalence of 4.3 per 10,000 children aged 8, 9 and 10 years, who were born in the Eastern section of Ireland in 1965-68.

I don't click on aut sqeaks sites... Can you tell me what I will see there please....

In the wake of today's new report from the U.S. Centers for Disease Control (CDC) stating that autism now affects 1 in every 110 American children, Autism Speaks, the nation's largest autism science and advocacy organization, called on the federal government to immediately step up its efforts – and dramatically increase funding – to address the growing national autism public health crisis.
      The CDC report, published in this week's Morbidity and Mortality Weekly Report (MMWR), states that 1% or 1 in every 110 children has been diagnosed with autism, including 1 in 70 boys. This represents a staggering 57 percent increase from 2002 to 2006, and a 600 percent increase in just the past 20 years. Other significant findings include that a broader definition of ASDs does not account for the increase, and while improved and earlier diagnosis accounts for some of the increase, it does not fully account for the increase. Thus, a true increase in the risk for ASD cannot be ruled out. Even though parents typically express concerns about their child's developmental progress before age three, the average age of diagnoses is not until 53 months, although diagnoses are occurring earlier than found in the 2002 study. The report uses the same methodology that produced the CDC's 2007 prevalence findings of 1 in 150 children with autism.

well this is all the sources I taked

I've seen so many numbers thrown around. I think that creates confusion and doubt in regards to the organization issuing the numbers. I think the one I hear most often is the 1 in 110 but I was thinking it was 1 in a 100 but I guess I was wrong. Whatever the number is, it affects a lot of people and families and friends and there needs to be more awareness as well as federal funding.
