Women in Tech: Female Developers By the Numbers - Lori Kozlowski, Forbes

It’s not a secret: There are fewer women in tech than there are men. Women take up only a quarter of the nation's tech jobs, though they make up half the American workforce. So, let’s run some numbers. Based on estimates from Q, an IT and Digital talent firm based in Los Angeles that specializes in tech talent in Southern California: Out of every 100 software developers/engineers in Los Angeles, approximately 10-12 are female. In 2011, only 17% of job placements (all for positions in technology in L.A.) were women. Only 7% of developers hired through Q were women.
