I am mostly looking at the column for editors making more than 100 edits a
month, as that is where the decline in the English Wikipedia has been most
pronounced, from 4804 in March 2007 to 3137 in November 2012. It's when
core editors leave in droves that you start to worry.

For comparison, the figures for March 2007 and November 2012 for the four
projects I mentioned are:

EN: 4804, 3137
FR: 676, 800
ES: 430, 486
DE: 1093, 1004
