With feminism slowly gaining ground around the world – or, in some cases, taking backwards steps – it’s important to check just how far we have to go in achieving equality and freedom for all girls.

This report ranks the best and worst countries to be a girl.

The report includes a 'Girls’ Opportunity Index,' which measures countries against five indicators: early marriage, adolescent pregnancy, maternal mortality, women in parliament, and secondary school completion.

The report reveals Australia has been outranked by countries including Serbia and Slovenia, placing a lowly 21st out of 144 nations. The two major factors contributing to Australia’s poor rating were the low proportion of women in parliament and a relatively high teen pregnancy rate.
