The Social Security Yearbook is an annual publication that provides comprehensive information and statistics about the Social Security program in the United States. This includes data on retirement, disability, and survivor benefits, as well as information about the Social Security trust funds and the demographics of the program's beneficiaries.

For example, a security guard company in Los Angeles might find the Social Security Yearbook useful for understanding the retirement and disability benefits that their employees may be eligible for. They could also use the information to help plan for the future and ensure that they are contributing to their employees' long-term financial security.
