Based and balanced is not the same definition. That's an interesting question, what would make it gender based or not; and feel thats a treacherous thing to go into for data scientist, maybe something left up for the sociologist to give us a definition.

But the statement was "balanced" and in the age ranges that social media covers the gender is at 50-50. It only becomes slightly different just past the social media age, as slightly more men die earlier from hard labor, risk, or war.
