LONDON: Women will have to wait 217 years before they earn as much as men and have equal representation in the workplace, researchinfo-icon said, revealing the widest gap in almost a decade.

Women are paid and achieve just over half as much as men in the workplace, the Worldinfo-icon Economic Forum (WEF) said, reporting an economic gap of 58 per cent between the sexes.

"In 2017 we should not be seeing progress towards gender parity shift into reverse," said Saadia Zahidi, WEF's head of education, gender and work.

"Gender equality is both a moral and economic imperative. Some countries understand this and they are now seeing dividends from the proactive measures they have taken to address their gender gaps," she added.

It is the second year in a row that the Swiss non-profit has recorded worsening economic inequality, which is calculated by measuring how many men and women participate in the labour force, their earned incomes and their job advancement.

Last year, WEF said women would achieve economic equality in 170 years, down from 118 years in 2015.

No country has closed the pay gap, WEF said, using data from institutions such as the International Labour Organisation, United Nationsinfo-icon Development Programme and World Healthinfo-icon Organisation.

Overall, Iceland, Norwayinfo-icon, Finlandinfo-icon, Rwanda and Swedeninfo-icon ranked highest among 144 nations measured on progress in equality in four areas: education, health and survival, economic opportunity and political empowerment.

Yemeninfo-icon, then Pakistaninfo-icon, Syriainfo-icon, Chad and Iraninfo-icon, ranked lowest.

Women fared much better in education, where equality could be reached within 13 years, WEF said, while closing the gap in political empowerment could take a further 99 years.

"Even though qualified women are coming out of the education system, many industries are failing to hire, retain and promote them, losing out on a wealth of capacity," it said.

The report estimated that closing the pay gap could add an extra $250 billion to the GDP of Britaininfo-icon, $1,750bn to that of the USinfo-icon and $2.5 trillion to Chinainfo-icon's GDP.
