Sadly, the data I have seen has always been of the "virtually everyone I know uses..." variety. In some cases, like that of ONCE in Spain, or similar government organisations, that information is accurate to the extent of identifying the majority case - 60% or more - but it is generally a very expensive bit of research that goes out of date extremely quickly, so people don't do it. You might do better to define much more precisely which users you mean (those who will sue? government employees? rich ones? all users?) or why the information is important. Virtually everyone I know uses Speakup and/or Gnopernicus as their main screen reader in english. Blindux I think is based on yasr, but is essentially its own package, for people who speak spanish (more important to Sidar and Americans - north and south than to the rest of the world, but I suspect the question is only related to users in the US. In some languages JAWS and Window-eyes are not available at all and they use something else). W3C used to have an activity trying to characterise the Web, and how people used it. It was packed up - I think in part because it turned out to be too hard to do more than guess or extrapolate from people one knows. (In that case the US votes overwhelmingly democrat, has a university degree, a passport, mostly works in high-paying jobs... ;-) I spend my life working with systems that are pretending to be a different system, so I can see how it is hard to find out what is really happening. Or you could point out to your client that in any case 83% of statistics quoted are really just made up, and most of the rest are gathered with a good dose of guesswork... cheers Chaals On Monday, Dec 29, 2003, at 20:27 Europe/Rome, Erika Noll Webb wrote: > > Does anyone have an data regarding the most prevalent screen readers? > I > have a client who wants to know which VERSION of JAWs and Window Eyes > are > the most prevalent right now.
