Does disproportionally mean unequally?

So I want to know that this statement actually means: "People with power have oppressed both men and women disproportionately."

Does this mean that people with power have oppressed men and women equally? Or unequally? What's the actual meaning here?

Solution 1:

If you had two groups of kids, one group in green shirts consisting of 20 kids, and another group in yellow shirts consisting of 50 kids, and you gave the first group 40 pieces of candy and the second group 100 pieces, you would have done a proportionate distribution of the goodies, as there would be two pieces of candy for each kid, regardless of the group they were in.

But if you gave the first group 100 pieces and also gave the second group 100 pieces then the distribution would have been disproportionate, since the numbers distributed were not in proportion to the sizes of the groups.

The quoted sentence is a little puzzling since the number of men and women is roughly equal, but it suggests that one group has been oppressed more than the other.
