In recent years, much attention has been focused on the roles that the private sector and federal government play in providing insurance and financial aid before and after catastrophic events. In this context, the authors examined (1) the rationale for and resources of federal and state programs that provide natural catastrophe insurance; (2) the extent to which Americans living in catastrophe-prone areas of the United States are uninsured and underinsured, and the types and amounts of federal payments to such individuals since the 2005 hurricanes; and (3) public policy options for revising the federal role in natural catastrophe insurance markets.
