March is National Women's History Month, a time to reflect on the many incredible achievements made by American women and to acknowledge the ongoing struggle for gender equality.

Thanks to the tireless efforts and sacrifices of trailblazing women who for centuries have fought to break down gender barriers and challenge injustices, huge strides have been made to close the nation's once gaping gender gap. Yet, as these numbers demonstrate, there is still progress to be made.

The U.S. Census figures below, while admittedly limited, present a brief demographic profile of America's female population today. The numbers highlight some of the areas where important gains in equality have been made and where notable disparities still exist.
