In relation to white women, women of color are disproportionally affected by the negative influence their gender has on their chances in the labor market. In 2005, women held only 14.7% of Fortune 500 board seats with 79% of them being white and 21% being women of color. This difference is understood through intersectionality, a term describing the multiple and intersecting oppressions and individual might experience. Activists during second-wave feminism have also used the term "horizontal oppressions" to describe this phenomenon. It has also been suggested that women of color in addition to the glass ceiling, face a "concrete wall" or a "sticky floor" to better visualize the barriers.
