This concerns the first half of the survey, with the second half covered by a separate blog post and report.
Note: Plans changed and the most-requested demographic data (on gender) was published as part of this blog post ahead of the general topline report (which is still to come): https://blog.wikimedia.org/2015/04/30/how-many-women-edit-wikipedia/
So this got delayed past the planned window earlier this year, mainly due to the need to coordinate (for reasons not related to this survey per se) about the aforementioned blog post, and other things took over, most recently Wikimania and the publication of the Q4 quarterly report. But following these, Terry, @Tnegrin and I agree that room should now be made for this and the two other remaining tasks (T91593,T91592) to be completed by the end of this month (August 31 PDT).
Update: Started publishing the material in time to meet that deadline, but held off with the already drafted blog post (combining the two previously planned ones) on the request of the Comms team because of another timely announcement going out on the blog. It should go out the next day instead.
