LA Times Best Science Book of 2025 Why is it so expensive to be a woman in America? From a rising star in economics comes the first comprehensive look at the costs women face and why the bill runs especially high for women of color--with a foreword by Chelsea Clinton. The "pink tax" has gained widespread recognition in recent years, but what happens when you look at the costs that define a woman's entire life, especially across racial lines? In The Double Tax, Harvard researcher Anna Gifty Opoku-Agyeman summarizes the disparities that women face as they navigate life's biggest moments. Not only do the numbers reveal that women incur higher costs than men, but also that Black and white women lead vastly different lives, marked by dramatic gaps in job opportunities, salaries, housing costs, childcare access, and generational wealth. She coins this gap as the "double tax," the compounded cost of racism and sexism. Through rigorous research and interviews with women across the country, Opoku-Agyeman calculates the extra money, time, and effort that women are expected and forced to pay at every stage of their life. While the evidence may be discouraging, The Double Tax offers actionable solutions for how everyday people, local communities, and global leaders alike can help relieve women of these costs for good. Only by understanding where the gaps are and where the double tax arises can we begin to even the playing field for all.
