(CNN) Citigroup is making progress toward shrinking its gender pay gap. But it still has some work to do.

Globally, the bank's female employees earned 27% less than men did, according to a new report from the company. That's a slight improvement over the 29% gender pay gap Citigroup reported for 2018.

This year's analysis also found that the median income for minority workers in the US was 6% less than the median income for non-minorities, down from 7% last year.

These "raw gap" numbers are not adjusted for seniority, job title or location, Citigroup said. The company began releasing numbers on gender pay in recent years amid pressure from investors

"The pay gap reflects a need to increase representation of women and US minorities in senior and higher-paying roles," wrote Sara Wechter, Citigroup's head of human resources, in a blog post
