If you’re a woman and want to be on an equal footing with men, it’s best to live and work in Belgium, Denmark, France, Latvia, Luxembourg or Sweden. The World Bank, which has tracked legal changes for the past decade, found these were the only countries in the world to enshrine gender equality in laws affecting work.

The bank’s women, business and the law 2019 report, published this week, measured gender discrimination in 187 countries. It found that, a decade ago, no country gave women and men equal legal rights.

The index assessed eight indicators that influence economic decisions women make during their working lives – from freedom of movement to getting a pension – tracking legal blocks to either employment or entrepreneurship. Each country was scored and ranked, with a score of 100 indicating the most equal. Only six were given full marks.

Research found that, globally, average scores had risen from 70 to 75. Of the 39 countries with scores of 90 or above, 26 were high-income. Eight were in Europe, including the UK, and central Asia, where parental leave was a key trend. Two, Paraguay and Peru, were in Latin America and the Caribbean. Taiwan was also among them.

South Asia had the biggest improvement in average regional score, recording a figure of 58.36 – up from 50 a decade ago. Sub-Saharan Africa increased from 64.04 to 69.63 over the same period, led by progress in Mauritius. Half the changes were related to work and marriage.

Countries in the Middle East and North Africa made the least progress, with an average increase of just 2.86, to 47.37.

The report was launched by the bank’s interim president, Kristalina Georgieva, who took over from Jim Yong Kim.

“Gender equality is a critical component of economic growth,” she said. “Women are half of the world’s population and we have our role to play in creating a more prosperous world. But we won’t succeed in playing it if the laws are holding us back.”

The report found that women’s rights advocacy groups had played a key role in driving reforms.

While the report noted significant progress overall, there remained much to be done to level the playing field. Instituting legal reforms did not necessarily lead to changes on the ground, and a score of 100 did not automatically mean 100% equality. Unequal pay is a major stumbling block. Women in Sweden earn 5% less than their male peers (in the UK they earn 8% less).

This represents a missed opportunity, said Georgieva. The global economy could be enriched by about $160tn (£120tn) if women earned as much as men.

“It is clear that giving space to women leads to richer societies,” she says.
