"A worsening performance on the wage equality for similar work indicator, dropping from seventh to 21st, partly accounts for this fall", the WEF said.
According to the report, no country has achieved gender parity when it comes to economic opportunities and work.
The Index measures equality between men and women in 144 countries worldwide in four key sectors: health, education and political and economic participation.
On top of that, women were spending about 44.6 per cent of their non-work hours on unpaid work such as looking after their families while the figure for men was 18.9 per cent. One metric was life expectancy: Chinese women outlive men by less than two years on average, compared with a global average of five years.
"The remuneration gap is captured through a hard-data indicator [ratio of estimated female-to-male earned income] and a qualitative indicator gathered through the World Economic Forum's annual Executive Opinion Survey [wage equality for similar work]", the WEF said. Only in the category of health and survival does the country perform worse now than in 2006.
China was at the bottom of the list for the third year in a row for sex ratio at birth.
The State has closed 97 per cent of its health gender gap, which is above the global average. This is a slight deterioration on 2016 when the gap was 68.3 percent and in 2015, when it was 68.1 percent.
Women around the world may have to wait another 217 years to get equality in the workplace, the World Economic Forum said in its 2017 report released on Thursday. India's Health and Survival ranking was 142nd previous year and on political empowerment it ranked 112th.
The report said that there was an "overall mixed picture and continued stalling of progress at the global level".
At the top of the Global Gender Gap Index is Iceland.
In recent years, women have made significant progress towards equality in a number of areas such as education and health, with the Nordic countries leading the fray. The top 5 is completed by Rwanda (4) and Sweden (5).
The further away the score is from 0, the higher the "distance to parity" in the country for that sub index appears to be.
Among the G-20 countries, France is ranked highest on gender parity at 11th place in the global ranking, followed by Germany (12), the United Kingdom (15), Canada (16), South Africa (19) and Argentina (34). The country is only 77% of the way to gender parity in economic opportunity, a gap that's been narrowing, but not as quickly as in other countries. Only six countries have closed the gap in both of these pillars. "Also, keeping in mind all the reforms happening at the moment, next year's report results seem to be even more promising".
About 23 per cent of the political gap has been closed, which is unchanged since a year ago against a long-term trend of slow but steady improvement.
