I do not know where he got his statistics but he is wrong and the statistics that he brought is wrong, yes statistics can biased and wrong. The fact is that 13% of the population live in poverty and all of them are all on welfare, hard welfare, and not just indirect welfare, so the number that 2% to 6% live on welfare does not make any sense.

Number of families on welfare has fallen from 5 million in 1994 and leveled off at 2 million in 2004. I didn’t find statistics after that.

There were 105 million households in the US in the 2000 census. Please tell me again how I am wrong now that I have laid out some sources for you.
I recognize these statistics are for households, not total population. It is probably true that people in poverty have larger households.
The problem with assuming that your 13% in poverty are all on welfare is that it doesn’t take much to get a large family under the federal poverty line. There are many conservative Christians, Amish, Mormons and others that have 6 or more children and do not receive government aid.
A family with 4 children is considered under the federal poverty line if it makes less than 29,500 per year. There are many areas of the country in which one can live well without needing that much cash flow.
