The above is a study of prostitution in Ireland, a survey of providers. (No idea why it is in a site called drugsandalcohol.) The average age started working is far above 12-14 (see below). The main reason given for starting is financial problems. None of this will surprise most ofus.
BTW, just because I am interested, of 84 surveyed, 36 are married or cohabiting, and another 27 have a boyfriend/girlfriend. Seems that this was the subject of various prior threads.
Regarding age started working, see Table5. Numbers reproduced here.
Age 13-15: 4
Age 16-18: 10
Age 19-21: 17
Age 22-24: 8
Age 25-27: 14
Age 28-30: 17
Age 31-33: 5
Age 34-37: 4
Age 35 +: 5
I like bringing facts to a debate. Helps to clarify what is opinion. Also when some quote 'facts' that are not it provides information on the source and how much to trust said source.
To be clear I am quoting a survey in Ireland, where prostitution is legal. Certainly our crusader from Portland will say she is quoting facts from the USA, so I will look for a similar survey in the USA.
