Commonwealth Fund

The Commonwealth Fund is a private foundation that aims to promote a high performing health care system that achieves better access, improved quality, and greater efficiency, particularly for society’s most vulnerable, including low-income people, the uninsured, minority Americans, young children, and elderly adults.

The Fund carries out this mandate by supporting independent research on health care issues and making grants to improve health care practice and policy. An international program in health policy supports innovative policies and practices in the United States and other industrialized countries.

The Commonwealth Fund is also a supporting organization of the Transparency Initiative at AAPOR, an initiative to place the value of openness at the center of the public opinion research profession.

Additional surveys will be added to the Roper Center collection in the coming months. More information can be found on the Commonwealth Fund website.


International Health Policy Surveys

In collaboration with international partners, the Commonwealth Fund’s international program conducts annual surveys of patients and physicians in 11 high-income countries. The surveys delve into financial barriers to care, chronic disease management, and satisfaction with care, among other topics.

Biennial Health Insurance Surveys

The Commonwealth Fund’s Biennial Health Insurance Surveys assess the extent and quality of coverage for U.S. working-age adults. Conducted over the last two decades, the survey uses three measures to gauge the adequacy of people’s coverage:

  •    whether or not they have insurance
  •    if they have insurance, whether they have experienced a gap in their coverage in the prior year
  •    whether high out-of-pocket health care costs and deductibles are causing them to be underinsured,        despite having continuous coverage throughout the year.
