The average age of entry into prostitution is 12 years old

59. I actually have no idea when most start

but the fact is that no matter when most start, if the average age one starts child prostitution is age 12, and there are any adults at all who start prostitution, then the average age as a whole would have to be higher. Your own link, BTW said 14, not 12, so even you apparently think the OP's headline is wrong by two years, which in the context of the average age of a child is a pretty big error. Now, I will say that I do think more people start being prostitutes as adults than as children. I don't know that and am willing to change my mind if the math says otherwise, but I do think that it is highly unlikely that the median age to start prostitution is under 16. For the average to be 14 or anything like it over all the median would have to be 14 or less since the data must be skewed right making the mean greater than the median. I think that there is quite likely a substantial number of people who turn to prostitution as young adults (18 to 25) due to drug use and/or other income issues. I find it quite hard to believe that this group wouldn't raise the mean or median age of being prostitution from either the 12 or 14 that is the average for children.
