Ethnic/Racial, Religious, and Demographic Predictors of Organ Donor Registration Status

Seems like a good proxy for citizenship (a la you would expect the core of a society to be more pro-society than the fringe). From this 2017 study: “Race/ethnicity, religion, and educational attainment were significant predictors of ODRS. Non-Hispanic whites (NHWs) were most likely to be registered as donors, with no significant difference between NHWs and Asians or Pacific Islanders. Non-Catholic Christians were most likely to be registered donors, followed by Catholics, practitioners of American Indian/Native American traditional religions, and Hindus, with Buddhists the least likely to register.”
