How good is the Social Security Death Index?
- or -
Why isn't my great-grandfather in there?
The Social Security Death Index is a computerized file of deaths reported to the Social Security Administration. Not all deaths are reported to them, and the file has only been kept since they began computerizing their records in the 1960's. Some deaths were entered into the database after the fact, but good coverage of deaths does not begin until the mid 1960's.
