Social Security Act

The Social Security Act is the U.S. federal law that created the Social Security system and established the legal framework for old-age, survivor, and later disability benefits.

It matters because one of the most important retirement-income systems in the United States is not just a benefit formula. It is a statutory program built through federal law.

Why It Matters

The Social Security Act matters because it defines the legal foundation behind a major share of household retirement income.

• it created the basic structure for public retirement benefits
• it became the basis for survivor and disability protections tied to work history
• later amendments expanded the scope of the broader Social Security system

That makes it a law-level term, not just a benefit-planning term.
