What Is the Center for Studying Disability Policy?

Statue of FDR photograph.

The Center for Studying Disability Policy was established in 2007 by Mathematica to inform disability policy formation with rigorous, objective research and data collected from the people disability policy aims to serve. The Center supplies the nation's policymakers with the information they need to navigate the transition to 21st-century disability policy. For over two decades, Mathematica has conducted many significant disability studies, including some of the first rigorous evaluations of employment supports for people with severe disabilities and the largest surveys of people with disabilities. More than 30 staff continues this pioneering work today through a wide range of innovative disability research and data collection. Read more.

Money Follows the Person Demonstration: State Long-Term Care Systems Before Implementation

The fourth report from the Money Follows the Person (MFP) Demonstration provides an early assessment of the balance of home and community-based care services (HCBS) and institutional long-term care systems in states before MFP was implemented. By looking at the status of these long-term systems state-by-state, the assessment helps to develop a baseline to measure the program’s impacts on long-term care systems.

Analysis of Medical Expenditures and Service Use of Medicaid Buy-In Participants, 2002-2005

When workers with disabilities “buy into” Medicaid by paying monthly premiums, states can offer them Medicaid coverage when their income and assets would otherwise make them ineligible. Using MAX data and Medicare claims files, this report provides the most comprehensive information to date on patterns of Medicaid and Medicare spending and service use among Medicaid Buy-In participants. Researchers found that combined inflation-adjusted Medicaid and Medicare expenditures for Buy-In participants more than doubled from $887 million to $1.9 billion between 2002 and 2005, as did program enrollment. However, they also found that, when compared with other working-age disabled Medicaid enrollees, Buy-In participants in 2005 incurred lower annual Medicaid expenditures. This difference suggests that Buy-In participants who are working may require fewer services or a less expensive mix of services than other adult disabled Medicaid enrollees.

A New Way of Measuring SSDI Beneficiaries Reentering the Workforce

This issue brief presents longitudinal employment and exit-for-work statistics for SSDI beneficiaries followed for 10 years from when they first received their award. These statistics are significant in that they show that the percentage who eventually leave the rolls for work is several times larger than one-half of one percent, a well-known number based on beneficiaries’ actions over a short period—a month or year. *Issue Brief

Six-Month Results from Accelerated Benefits Demonstration
