I am trying size the Interaction Design market. Does anyone have data
on the number of interaction designers in the US and world wide?
I found some oblique references, but nothing that could give an
accurate picture of the general population.
I looked at the online job postings to see how many open positions
there are (about 1600) and at conference attendance and various
organization's membership numbers but all those data points require
some ridiculous amount of guessing. What's the ratio of open
positions to total positions? 10 to 1? Anyone have a guess? It must
be highly variable in any case.
Ultimately the best data for my purposes would be sales figures for
software like Axure or some other special interaction design type of
software, but I don't imagine that I'll be getting ahold of that kind
of information :)
So, any guesses, or bright ideas on other data points?
