Utilizing the Social Security Administration’s Disability Analysis File

Since 2011, the Social Security Administration has offered its Disability Analysis File (DAF) on an annual basis, compiling data from a range of internal and external data sources into one cohesive database with additional composite variables. With historical data reaching back to 1994, these files contain data on all those individuals with disabilities below retirement age who have received benefits under the Supplemental Security Income (SSI) or Social Security Disability Insurance (SSDI) programs. Data on these beneficiaries include one-time variables such as date of birth and Social Security Number, as well as historical and longitudinal data (e.g., eligible and actualized benefit payments, State of residence) tracked across multiple years. With the ability to retrieve reliable longitudinal data on beneficiaries with disabilities, the DAF is an important resource for those looking to perform any sort of analysis on this population.

More information about the DAF can be found on the Social Security Administration website at:

Remembering the Section 504 Sit-In

Sections 504 and 508 of the Rehabilitation Act of 1973 are key to protecting the rights of people with disabilities. Combined, they aim to ensure people with disabilities can access any program or activity receiving Federal funds and to eliminate barriers in IT and encourage the development of technology to achieve these goals.

April 5 marked the 44th anniversary of the Section 504 sit-ins. The 1977 sit-ins resulted from years of frustration at the slow pace of regulations and marked a turning point in the Nation’s push for regulations protecting the rights of people with disabilities.

Section 504 passed into law as part of the Rehabilitation Act of 1973, one of the first U.S. federal civil rights laws offering protection for people with disabilities. It set up the groundwork for all future legislation protecting people with disabilities, such as the Americans with Disabilities Act (ADA).

Though the law said “no otherwise qualified handicapped individual in the United States shall solely on the basis of his handicap, be excluded from the participation, be denied the benefits of, or be subjected to discrimination under any program or activity receiving federal financial assistance,” the Government was slow to create and enforce regulations enforcing the law. The law would prohibit any entity receiving Federal funding, such as airports, post offices, universities, and Government facilities, from discriminating against anyone because of a disability.

No regulations were issued from 1973 to 1977, despite attorneys in the Office for Civil Rights drafting regulations and sending them to the Secretary of Health, Education, and Welfare (HEW) to publish for public comment. Guidelines from HEW would become guidelines for other Federal agencies, so this was important step. Disability rights organizations advocated for the regulations and staged protests and grassroots campaigns to see their passage. However, concerns about costs and enforcement, and pushback from covered entities such as hospitals and post offices, slowed passage.

But by 1977, frustration erupted. HEW Secretary Joseph Califano was tasked with studying the Section 504 regulations but established a task force that did not include anyone with a disability. National protests were organized.

The 504 Sit-In began April 5, 1977. Disability activists demonstrated at HEW offices nationwide, demanding the Section 504 regulations be signed. Sit-ins lasted at several of the offices, most notably in San Francisco. While many of the protests dispersed after a few hours, the peaceful protest in San Francisco lasted 25 days.

Persistence paid off, however, as Califano signed the regulations on April 28, 1977. The grassroots campaigns and ongoing protests showed that people with disabilities were not to be ignored, and forged partnerships that would later draft Federal laws, such as ADA, that provided for nondiscrimination on the basis of disability.
