On International Women's Day we're looking at one industry where there is a massive shortfall in women - coding.
Only around 30% of all female students across the world select subjects related to Science, Technology, Engineering and Mathematics (Stem), according to UN data.
But change is coming in Africa - as women are teaching themselves to code.
Co-founder of African cryptocurrency exchange BuyCoins, Ire Aderinokun told the BBC's daily business programme for African audiences Money Daily that a lot of women are taught that "Stem in general is just not for them".
But she took matters into her own hands.
"I am almost completely self-taught," she said.
"I just learnt by looking at websites and doing online courses so that there was nobody who could actually stop me from learning and getting the education I needed to have the role that I have."
Theresa May has been criticised after only taking one question from a woman during a news conference on International Women’s Day.
BBC Hereford and Worcester
Dozens of people dressed as munitions workers from the two World Wars have cycled around Hereford today to mark International Women's Day.
They rode between historic sites such as the shell store and Bullinghope Church to honour the thousands of women who worked at the Rotherwas factory, near Hereford.
The women were nicknamed Canary Girls as, for some, the effects of their work were immediately visible - a lurid shade of yellow that stained their skin and hair.
Today's ride was organised by Lin Mathias as part of her art degree.
We're celebrating our own canary girls, they are the munition workers that worked at Rotherwas so everywhere we go on the ride is something specific to their lives because they didn't just make bombs."
