Look, I don't have to "justify" anything. My initial comment was intended to add to yours, not to argue about a minor point or quibble about the meaning of simple natural language sentences such as "they have to work". I didn't assert or tried to prove that 76% is correct, I wondered why you thought 76% is implausible, as it seems totally plausible to me, that's all.

> Do you have the slightest bit of evidence that exactly 76% of the women need to work,

I never said that.
