She Figures 2015
'Working towards gender equality is an essential part of European research and innovation policy. Since 2003, the She Figures have monitored new developments related to careers, decision-making and, most recently, how the gender dimension is considered in research and innovation content.
More and more, European women are excelling in higher education, and yet, women represent only a third of researchers and around a fifth of grade A, top-level academics. Although the number of female heads of higher education institutions rose from 15.5 % in 2010 to 20 % in 2014, there is clearly still a long way to go before we reach gender equality in European research and innovation professions.'
