The gender-based wage gap in the United States has narrowed in recent years, but disparities remain: national median earnings for civilians who worked full-time, year-round in the past 12 months was $53,544 for men compared to $43,394 for women, according to a report from the U.S. Census Bureau.

Equal Pay Day — timed to represent how far into the year women must work to equal what men earned the previous year — is on March 15 this year. That’s earlier than it’s ever been since its inception in 1996. Last year, it landed on March 24, according to the Census Bureau.

Places with a wage gap above $15,000 included Wyoming, $21,676; Utah, $17,303; and the District of Columbia, $16,032.

In Florida, the wage gap is $7,705, with the median earnings for men at $45,187 and $37,482 for women.

The selected top occupations for women were elementary and middle school teachers; registered nurses; and secretaries and administrative assistants, except legal, medical and executive.
