Here is what I am trying to do -- to determine if there is some
correlation or benchmark to paid membership in a low annual fee sports
organization
with outside forces such as magazine subscritions, CPI, S&P 500 etc
(below)-- there is no right answer -- want to determine what is
"correlated" to membership acquisition and retention -- by using DATA
-- (versus just opinion)
From Dec 1999 - to present --  
1. Would like golf magazine paid subscriptions, by month. [If this is
cut by age and gender better.]
2. Sports magazine paid subscriptions by month. [if cut by age and
gender great]
3. Would like the S&P 500 Index by month.
4. Would like the CPI by month
5. If there is any "charitable giving" or "donor" data points by month
--not sure hwere ot get this if any
5. Any other economic data points that may be used as a comparision
and or correlation for or insight for the demographic market 35 years
old plus
