For most of the seventeenth and part of the eighteenth centuries, male slaves outnumbered female slaves, making the two groups' experiences in the colonies distinct. Living and working in a wide range of circumstances and regions, African-American women and men encountered diverse experiences of enslavement. With increasing numbers of kidnapped African women, as well as those born into slavery in the colonies, slave sex ratios leveled out between 1730 and 1750. "The uniqueness of the African-American female's situation is that she stands at the crossroads of two of the most well-developed ideologies in America, that regarding women and that regarding the Negro." Living both female and black identities, enslaved African women faced both racism and sexism.
