I will have to look into Hill & Shaw, but would note that the Wikimedia Foundation itself reported the figures from the UNU survey as they stood (see e.g. p. 8 of the February 2011 Strategic Plan: "According to the study, over 86% of contributors were male"). 

NB., that was before the Hill & Shaw paper was published, which was 2013 :) Hill & Shaw is *probably* the best estimate of the gendergap we have so far, but everyone -- including the WMF and the researchers involved -- knows that the data can be improved. And hopefully it will be, with future editor surveys and more research!
