The researchers argue that institutional racism in police departments targets minority communities with policies like stop and frisk.
A new study by Harvard Medical School and Tufts University finds that immigrants use significantly less health care than US-born individuals, with lower rates of utilization and expenditures. Immigrants also pay more out-of-pocket health care payments, effectively subsidizing private insurance and some public programs like Medicare.
