For some reason, I never thought to ask that question when I was in high school and college in the 1960s.
Only White women couldn’t vote?
So... Black women could?
No, population was counted, period. Still is.
The point was for the slave states to get some extra population counted for leverage in Congress.
So, no, females were always counted, so black slave females would be counted, too.
BTW, women could vote if the states chose to make it so. They had voted in NJ in the beginning.
