This looks nice! And I like the link between the rings and the bars.

I'm a bit thick. It took me a few minutes to realise that the rings of the circle are independent. For example, there can be female humans, all the humans are not male.

On the bar charts you start at 0% (which is good), but you don't finish at 100%, nor on a similar number. One chart finishes at about 15% and another at about 30%. So at a glance the hight of the bars looks similar. I guess the width of the bars compensates? (And the race bar chart numbers add to 99%. Is that a rounding thing?)
