More than 13% of American adults -- or about 34 million people -- report knowing of at least one friend or family member in the past five years who died after not receiving needed medical treatment because they were unable to pay for it, based on a new study by Gallup and West Health. Nonwhites, those in lower-income households, those younger than 45, and political independents and Democrats are all more likely to know someone who has died under these circumstances.
