I saw an interesting discussion on LinkedIn asking about what areas experienced the most membership growth — or loss.  I modified my club type script and ran it against the 2009-10 data, and got some interesting data.

First, to no great surprise, the country with the greatest loss was Haiti, down 323 members (net change, July 1, 2009, to June 30, 2010).  Not far after that was Taiwan (down 166), Netherland Antilles (down 47), and Kuwait (down 29).

The biggest gains were United States with 1,962 members (net increase), Canada (up 1,079 members), India (920 members, no surprise there!), China (881 members), Australia (620), and Malaysia (481).

Within the US, Virginia had the biggest net membership loss (down 197 members), Alabama (down 116), and Indiana (down 103).  The biggest increases were California (up 1,962 members!), Texas (up 1,219), Florida (up 935), New York (up 766), and Illinois (up 504).

Here’s a graphic showing the data — brighter green is more total members added in 2009-10 (NOT adjusted for population!).
