As baby boomers move into retirement each year, the Census Bureau projects that the age 65-and-older population will grow over 50 percent between 2015 and 2030. Several issues call attention to the retirement security of this sizeable population, including a shift in private-sector pension coverage from defined benefit plans to defined contribution plans, longer life expectancies, and uncertainty about Social Securitys long-term financial condition. This book examines the financial resources of workers approaching retirement and retirees and the evidence that studies and surveys provide about retirement security for workers and retirees.
