Social Security Administration
This booklet explains the benefits Social Security can provide for the family. It is divided into two sections-- if you are currently working, the first part tells you what kind of survivors benefits your tax dollars are paying for and how those benefits are earned; if someone in your family has died, the second part of the booklet explains how to sign up for Social Security benefits and what you need to know after benefits start.
