Social Security Death Index

The Social Security Death Index (SSDI) is a database that contains information about individuals who have died and were eligible for Social Security benefits in the United States. It includes names, Social Security numbers, birth and death dates, and sometimes information about last residences. The SSDI is used primarily for genealogical research, verifying identities, and fraud prevention. Researchers, genealogists, and certain institutions utilize this data to trace family histories and ensure accurate records, making it a valuable resource for understanding social security-related issues and demographic trends.
