You were asking about measurement. There are a series of studies that have been done municipally across the country. It's possible, using that data, to get a broad picture of the number of people who are homeless. It's clear when you're working at the municipal level that there is a major slice of people who are homeless and are dealing with addictions and mental health issues. That's partly because the services that have been provided at the local level have been inadequate to accommodate the mental health issues they present.
