Hi.

I would like detailed information on the market size of the MBTI
instrument (and other personality tests), in the US market or other
markets.  Please feel free to add any information you find relevant to
meet this end.

1. How big is the market of MBIT instrument buyers in number of users
and US$ - compared to total market size.  (ex. US: market of 1 million
users out of pop. of 300 mill.)

2. What is the market share of online based tests over personal interviewed test?

3. What are the trends in use of the instrument?

4. All Q's repeated, if possible and applicable, for other comparable
personality tests.

Thank you!
