User:WereSpielChequers/Admins by year

''' December 2009 - Admins by year of account creation and year of RFA on the English Wikipedia. '''

Findings
Wikipedia's admin corps is heavily skewed to very longterm users. Less than 2% of administrators have under two years tenure as editors, and there are still more administrators who started editing in 2002 than there are who started editing in 2007.

Anomalies

 * 1) Admins who have created a new account and had the bit transferred over from their old account are counted in the year their current admin account was created.
 * 2) RFAs and current admins won't tie up as former admins have not been filtered out of the RFAs.
 * 3) There is a discrepancy of 9 between the 1,698 divided by year and the 1707 admins in total that day - as I started calculations at the end these are likely to be early admins. An extract or bot would probably need to be run to get an accurate count.
