Changes

We examined all leaders in companies from 1980-2016 who have the titles of either chariman, CEO, CFO, COO, CIO, CTO, board member, President, Vice President, Founder, and Director. Of company members with those titles, 29.8% were women. Of those women leaders, 22% were CEOs, 14% chairwomen, 27% CFOs, 26% COOs, 31% CIOs, 12% CTOs, 25% board members, 20% presidents, 34% vice presidents, 23% founders, and 39% directors. Generally, the percentage of women in "leadership roles" in companies has trended upwards since 1980.

*(here, see if number of CEOs in 1980 is different than number in 2015 because that would show if women in major leadership positions has changed over time)
