I’ve updated the statistics that I regularly produce from our changeset dump, see stats page on wiki.openstreetmap.org, to the end of Q3 2014 numbers.

The well known trends continue with continuous growth in every category with a total of 447’883 contributors. Of special note is

showing that at the end of the third quarter we have already had slightly more active contributors than in the full year 2013.

August 2014 showed the 2nd highest increase in contributors in the history of the project with over 10’700 new mappers joining OpenStreetMap. It is not unwarranted speculation that this was due to the tenth anniversary celebrations.
