International Social Security agreements (also known as "totalization" agreements) have two main purposes.
- They eliminate dual Social Security taxation when a worker from one country works in another country and is required to pay Social Security taxes to both countries on the same earnings.
- The agreements help fill gaps in benefit protection for workers who have divided their careers between the United States and another country.
For those tables showing benefits in force, the tables also show the annual number of awards and terminations. Terminations are calculated using the number in force at the beginning and end of a year and the number of awards in the year.
