Hi All,

Thanks, Christophe, for those excellent statistical resources.  
Some recent US findings are at:

http://www.cdc.gov/nchs/fastats/disable.htm
http://www.census.gov/hhes/www/disability/disability.html

But none of these figures, and as Christophe notes, none of the 
other national or international stats go where *we* want them to 
go: a unified, cross-cultural definition of disability that can 
be used to identify people who have difficulty or are unable to 
use specific technology products and services.

That is, we'd like to know more about how many people would have 
trouble seeing text in specific color and contrast combinations, 
or using a mouse to hit a 5 mm. square screen target, or hearing 
an alerting tone at 3kHz.  These statistics would be useful for 
both technical and "business case development" reasons.

I would be interested in discussing these needs with others so as
to be able to present specific requests to EU, UN, US, and other 
disability statistics gathering programs.  I will be at AAATE, but
we don't have to wait until then.

If you are interested, please reply to me directly (so as to keep
this list on track).  If you can host a separate list, please offer
to do so in your reply.
