IWPR was founded in 1987 when Heidi Hartmann and others saw a need for an organization whose distinct purpose was to develop policy research that focused on women. IWPR came onto the scene with a bang, releasing its first research results and testifying before the U.S. Senate with findings on the costs to American women and taxpayers that result from women's lack of job protection after an absence due to childbirth. IWPR released Unnecessary Losses: Costs to Americans of the Lack of Family and Medical Leave in 1990, and in 1993, the Family Medical Leave Act (FMLA) was signed into law, giving employees access to unpaid, job-protected leave for specific family and medical reasons including the birth or adoption of a child.

Since then, IWPR's research has informed programs and policy debates on a sweeping array of topics including proposing women-friendly poverty policy, promoting women's leadership and getting more women into politics, reducing the wage gap and encouraging more women to enter science and technology fields, increasing wages for child care workers, and improving low-income women's access to education.
Using a growing tool chest of research methods—including analysis of large datasets, original surveys, evaluation research, and cost-benefit analysis—IWPR has measured and tracked women's status in the U.S. and around the globe and assessed policies for their gendered impact, providing technical assistance related to dozens of local, state, and federal policies and policy proposals. IWPR has published more than 600 reports, fact sheets, and research-in-briefs that place women at the center of analysis. IWPR’s convenings and conferences have connected thousands of researchers, advocates, and policy leaders. Future IWPR events will continue to provide a unique venue for addressing policy through a gendered lens.
Today, in collaboration with its many partners and supporters, IWPR serves as a powerhouse of groundbreaking research targeted at eliminating gender disparities. IWPR’s work is cited in hundreds of news stories each year, including by prominent national and international news outlets such as The Rachel Maddow Show, PBS NewsHour, The New York Times, The Washington Post, The Economist, and many others. It has built a reputation as a rigorous, trusted, and objective research organization. IWPR staff continue to testify as experts both in Washington, DC, and in state houses across the country.
