Women are closing the wage gap with men, but they still have a long way to go, according to a Pew Research Center report released Friday.

White women have shrunk the hourly wage gap, earning 82 percent of what men earned in 2015, up from 60 percent in 1980. Black women saw a lesser rise on the ladder to pay equality with white males during the same period. They earned 65 cents for every dollar of white male income, up from 56 cents in 1980.

Among major ethnic groups, Hispanic women are climbing the slowest and have the furthest to go. They earned 58 percent of what white males did, rising from 53 percent in 1980.

The researchers attributed a major part of the improvement to a significant increase in the education levels and workforce experience of women over time.

College-educated black and Hispanic women earn 70 percent of white men with degrees earn, while black and Hispanic males do better, earning 80 percent.
