The health care system in the United States has been called the best in the world. Yet wide disparities persist between social groups, and many Americans suffer from poorer health than people in other developed countries. In this revised edition of Health Disparities in the United States, Donald A. Barr provides extensive new data about the ways low socioeconomic status, race, and ethnicity interact to create and perpetuate these health disparities. This thoroughly updated edition focuses on a new challenge the United States last experienced more than half a century ago: successive years of declining life expectancy. Exploring the growing role geography plays in health disparities, Barr asks why people living in rural areas suffer the greatest increases in these deaths. He also analyzes recent changes under the Affordable Care Act and considers the literature on how race and ethnicity affect the way health care providers evaluate and treat patients.
