This International Women’s Day, we recognize the women who have helped shape opportunity in housing, finance, and beyond.

A major milestone came in 1974 with the Equal Credit Opportunity Act—ensuring women’s income could be counted when qualifying for credit and mortgages.

Trailblazers like Shirley Chisholm and Barbara Jordan helped pave the way toward greater equality and opportunity.

Today, we celebrate the women continuing to move industries forward.
