Welfare also went up. The problem is that their could be numerous reasons indicators go a certain away. That would also include how the government classifies what.is homeless, etc..
People pick and choose which statistics they make stick. For example, many indicators and categories have had positive results since President Obama came into office. A convenient response for this is to say he had nothing to do with the positive results, but everything to do with the negative results. That's picking and choosing and proves no correlation when taken individually. However, when all indicators are gathered across many spectrums we'll find this president to be one of the best ever.
