They're a very difficult population to account for, that's for sure. I think that in our first slide we say that in the survey on mental health we have not captured the homeless population.
This slide is from another survey and it was a retrospective question. I think the question was whether there was a period in someone's life when they didn't have a place or a regular house or something. It's people living out of their cars or on the street and it's still a population that we're reaching. People who are maybe chronically homeless, we don't reach.
