Recent US Data Shows Autism In Children Vastly Higher Than in Adults

There seems to be nothing like the numbers of adult autistics compared to children in the USA – see the graphs below.

In 2005, even with claimed  “better diagnosing and greater awareness” comparative numbers [ie. not total figures for the USA]:-

  • 5800 children age 3 to 5 – [ie. only a 3 year age gap]
  • 275 adults aged 52 to 61 – [ie. over 10 year age gap]
  • 63 adults aged 62 to 99 – [ie. over 38 year age gap]

If children older than 3-5 were included so that the age ranges were comparable with the adults, the increases would be greater still.

If autism had always been at the levels seen in children, you would expect the numbers in adults to climb to similar levels as in children or even faster if no one was looking at anyone of these older ages much before 1992.  But the figures are much lower for adults.

  1. Hi – I can’t help you with this particular problem.

    BUT – one way I thought of to tackle this whole issue of the increase in autism incidence was to ask a question in the Scottish Parliament about the figures for how much money had been spent on training for those who diagnose autism. As you can see, they used a standard excuse for avoiding giving a reply:-

    S2W-26127 – Rosemary Byrne (South of Scotland) (SSP) (Date Lodged Monday, May 22, 2006): To ask the Scottish Executive what the costs were of providing training in the diagnosis of autism in each year from 1999 to 2005, broken down by NHS board.
    Answered by Lewis Macdonald (Thursday, June 01, 2006): Information about the costs of training in the diagnosis of autism is not held centrally.
    The Scottish Executive is supporting four training pilot projects in the use of diagnostic tools to develop expertise in diagnosis across a wider range of professionals.

    I used this PQ as a reference, along with the recent MIND study, as part of evidence that I recently submitted to the Health and Sport committee of the Scottish Parliament:-
