Health insurance, however, is the top health provider, with nearly a quarter of the US population paying premiums for health care.
The Kaiser Family Foundation, a nonprofit health policy think tank, has found that the median premium for an individual in the United States is $1,076 a month.
This is about double the median annual income of the typical American, according to a report released in February by the National Bureau of Economic Research.
Health insurance also has been a key contributor to a robust expansion of health care options in the US, as well as to a reduction in health care costs and the quality of care, according the National Center for Health Statistics.
Yet, despite all of these benefits, the healthcare industry continues to face a number of challenges.
The Kaiser Family, for instance, found that health care spending has fallen to the lowest levels since the recession.
Another challenge is that the US has been unable to meet demand for health insurance policies, which can be difficult to predict in a country where insurance companies are notoriously difficult to track.
