Politics,policy making,data, and the homeless

Abstract

It is often said that a major obstacle to crafting effective policies concerning home‐lessness is the large uncertainty associated with estimates of the extent of the problem. Such uncertainty is due largely to the difficulties of identifying a “hidden” population. But how true is it that effective policy making for the homeless depends upon counting their population accurately? This paper reviews some critical relationships among politics, policy making, and data; examines data requirements for policy making affecting the homeless; argues the case for relative rather than absolute measurement; and assesses the importance for public policy of data problems in this area.
