Clarified above. Some homeless do manage to get ordinary waged work but given the requirements of most employers, it's not surprising that these poorest people don't appear employments statistics (the canard raised by the post I was replying to).

I don't have statistics and I suspect that getting statistics here is very difficult. A homeless person has little interest in answering a survey and certainly no one wants to appear homeless so just about any data source is going to be iffy.
