USCF members by year

Does anyone have an idea of USCF membership by year (going back as many years as possible)?

I have heard in the past that the USCF had its heyday during the Fisher boom years. However, I cannot imagine that there were even a fraction of scholastic players back then compared to today.  The number of young players has boomed.  There are also far more US citizens today than in the 1960s and 1970s.

Thanks!  It also says:

"As of 2014 membership is over 80,000, including over 50 Grandmasters, and USCF operations have recently returned to a break-even basis."

Hopefully they can get to 100k.
