This report describes how a woman's nation changes everything about how we live and work today. Now for the first time in our nation's history, women are half of all U.S. workers and mothers are the primary breadwinners or co-breadwinners in nearly two-thirds of American families. This is a dramatic shift from just a generation ago (in 1967 women made up only one-third of all workers). It changes how women spend their days and has a ripple effect that reverberates throughout our nation. It fundamentally changes how we all work and live, not just women but also their families, their co-workers, their bosses, their faith institutions, and their communities. Quite simply, women as half of all workers changes everything.
