Your comparison is odd. If you are poor, you are poor. So a poor woman, poor black male and a poor white male would be equally poor.

Seems to me more interesting is the risk of being poor. I think you'll find that there are a lot more poor men than poor women. I guess this is the case because 90% of homeless are male, and men tend to be more prominent on the extremes (more rich men and also more poor men than rich/poor women). Feel free to research the actual data, though.
