which provides objective analyses of how the country’s changing health care system affects individuals and families. In 2007, the company launched the Center for Studying Disability Policy (CSDP), to inform disability policy formation with rigorous, objective research, and data collected from the people disability policy aims to serve. CSDP provides leadership and support for disability research and data collection conducted by Mathematica. In early 2008, Mathematica created the Center for Improving Research Evidence (CIRE), to identify, assess, and disseminate results from quality, rigorous research to inform evidence-based policymaking. CIRE also provides technical assistance in designing, conducting, assessing, and using a range of scientific policy research and evaluations to support a growing national and international research base. In 2010, Mathematica established the Center on Health Care Effectiveness (CHCE), a resource for policymakers, the public, and other stakeholders. In 2013, Mathematica established the Center for International Policy Research and Evaluation (CIPRE). Its focus is to provide research-based information to funders and policymakers addressing global development issues. Structure Mathematica operates three business divisions: health, human services, and international research. Today, the company centers on research consultation for policy topics including disability, early childhood, education, family support, health, international, labor, and nutrition. The company specializes in program evaluation, policy analysis, survey design, data collection, data management, and interpretation. In recent years, it has begun offering services in data science, design, and visualization.
