I have seen several agency ladies and they all live in other states so you would have to exclude these women.  How many are from out of town is unknown and I don't think we would ever know unless you sampled every provider from every agency.  I doubt this business is hurting even with the economic downturn because it seems like agencies are adding new girls to the mix regularly.  That could be due to turnover or maybe constant demand or a little bit of both.
