For the record:

This is based on geolocated IP addresses from a few months back. Note that these are based on number of EDITS, not on number of EDITORS (which is harder to evaluate). A slim majority of edits to enwiki come from the US.
The corrolary to this, incidentally, is that 50% (give or take) of all actively contributing Wikimedia accounts just now are on en.wp. I know there'll be overlap, so a more reliable (ha!) method, edit count...
A shade under half of the edits to all Wikimedia projects made in May (since the figures were handy) are on en.wp. Allowing for some US participation on other projects, that's ~ 1/4 to 1/3 of all "involvement" across all Wikimedia projects being from the US. Which seems a fair enough, if arbitrary, figure.
(It'd be interesting to see the statistics for US involvement on es.wp, the other major language wikipedia I would expect them to contribute to, if they're available.)
