In the United States, the average age a girl starts menstruating is 12. However, this does not mean that all girls start at the same age. A girl can begin menstruating anytime between the ages of 8 and 16. Menstruation will not occur until all parts of a girl's reproductive system have matured and are working together.

There usually about 12 - 13 years old. However, girls can as young as 9 or as old as 15 in some cases. It depends on the girl.

Well, here it is; Two of my girls started at 10, one started at 12. My niece was 9, and my little sister started at 10. So, these days in pumped up steroidal meat products and all the insecticides in our vegetables and fruits, it seems the average would be between 10 & 12.
Hope this helps...
