2005 Census numbers show that Hispanic women make less than Black women.. so no black women are not at the bottom. The gap between what white women make on average and black women is only a couple of thousand a year if that.

Those numbers do not include the fact that men typically work longer hours than women (overtime) and women typically take time off to care for children, when you remove these variables the gap between a woman's salary and a male's is VERY close.

Simple research goes a long way before drawing conclusions.

Congrats on the raise, good advice I've received is to invest the raise and continue your standard of living.
