It looks as though there is good information, in detail, about who receives welfare benefits and a myriad of other related details at MDRC (Manpower Demonstration Research Corporation).

Of particular interest might be their A Profile of Families Cycling on and off Welfare .

I make NO claims as to their information and know nothing about them except what I've just seen on their website which I just found, but it looks worthy of further reading, imo.
