RUSA Member Retention

Two years ago, I posted the active RUSA membership count early in the year.
I was wondering what the active count is now compared to then.

Yesterday, Jan04, about 9 am EST, the active membership was 2181.
Compare that to Jan-04-2013, 4 pm EST was 2184.

Seven hours short of of exactly two years later -- active membership down by 3.
Hmmn.

===================================================

Btw, I did check the active membership late in December 2015;
There were over 4000 active members.  

===================================================

[Edit Feb-12-2016:  about 8 pm EST, active membership 2717.  
Compare that to Feb-07-2014, when membership was 2732. 
Five extra days, membership down 15.]
