1)Please give the number (national if possible, California only if you
can't get national numbers)of Psychologists, Marriage Counselors and
Social Workers for the year 1965 and the year 1980 and 2002.
2)For those same years (1965,1980,2002)give the number of marriages
and the number of divorces (national if possible, California only if
not).
3) Number of Graduate Training programs in Psychology and Marriage
Counseling in 1965 and in 2002.

Many of the states have changed the licensing rules since 1965 so
comparisons may not be very meaningful. Besides the 3 disciplines you
mentioned there are likely several more in between, in some states.
 Social worker may be a very broad category in some states. I presume
you do not want to distinguish between government and private sector.
How do you want to deal with persons trained in these disciplines, but
working in a job description that does not quite fit any of them?

Thanks for your quick response. I want to be able to make a general
statement. It doesn't have to be precisely verifiable. For example, if
I could say that in 1965 there were 10,000 mental health professionals
in the U.S. (including government and private, social workers and
psychologists etc and in 1980 there were _____ and in 2002 there were
_______, if the numbers were honest without being accurate down to the
penny- I'd be fine with that. I'm wanting to parallel the number of
practioners of 'mental health' with the number of failed marriages and
see what, if anything, can be drawn from that. thanks again. Stephen
(marriagedoc.)

But how would you know whether failed marriages caused an uptick (or
downtick) in mental health numbers or whether increased levels of
mental health caused more marriages to fail? I hope you are not trying
to do anything important with this kind of imformation.
