The Samoa Observer reports the discrepancy is contained in a recent report from the Bureau of Statistics for March 2019.
The report says about 56 percent of the work force are men who command 54 percent of the country's total wages.
But it says the average quarterly wage for women is $US210 more than men, (6,020 tālā for women and $5,496 tālā for men) making the average annual wage of women about 12 percent higher than men.
