You know, I don't. I have something here that shows that it's gone up fairly significantly since the time of the Taliban, and it's also much higher among younger girls. For instance, I recently read that in Bamyan province and in some of the Hazara provinces, up to 43% of the girls are in school.
In places where I worked, in eastern Afghanistan, in provinces like Paktia province, Wardak province, or Logar province, it changes a bit among districts, but the number can be as low as 10%, 20%, or 30%. It really is a fairly dramatic increase between the different provinces. I'd say that on average, it's probably somewhere between 20% and 40%.
