The membership numbers are contained in the Treasurers report. TCA members can go to the web site and look at the report themselves. The information is for 6/14.
This is a far cry from the days when there was a directory printed annually. I think I saved my last one, but I am uncertain. As I recall, it contained a lot of information, including number of members in each state, and a list of the number of members per year. I'll have to go see if I can find my copy.
Update: I have a printed copy of the Spring 2008 directory. I think it was the last one printed. I don't see a report showing the number of members in each state (I am positive that at least some older editions did have that). It does have a table listing the total membership and number of people registered for the annual convention by year, for 1955 to 2007.
