It covers only people in traditional Medicare, where Medicare pays each bill itself. People in private Medicare Advantage plans are left out. When areas are combined, places with more people in traditional Medicare count for more.

Combining areas: an average weighted by MEDICARE.FFS_ENROLLEES.

Population makeup

How this measure varies with the racial and ethnic makeup of counties. Every group is shown, whatever its rank. These are links across counties: they describe places, not people. They say nothing about any person’s risk or behaviour based on their race. Counties with a larger share of one group also differ in much else, such as income, segregation, region and history. The adjusted figure only accounts for density, income and education.
