Over the past three decades, homelessness has persisted as a serious problem in the city of Chicago. However, throughout that time, a comprehensive, reliable figure for the number of people who do not have a home has not been determined. This is a significant gap not only in our public records but also in our public policy. By not adequately accounting for the city's homeless population, we are unable to understand the true scope of the problem. Thus, we are ill equipped to come up with realistic strategies and adequate resources to address homelessness.
