A new study finds the death rate for Native Americans — which was already higher than other groups — is much higher than previously thought. The analysis just published in the Journal of the American Medical Association (JAMA) finds the gap in life expectancy between Native Americans and Alaska Natives and the national average is almost three times wider than what official statistics say it is. The researchers point to the fact that more than 40% of death certificates misidentify Native Americans and Alaska Natives. One of the study’s researchers says the discrepancies indicate “statistical erasure” in routine public health data has obscured the severity of a mortality crisis among Native people. We’ll get a handle on the new study and what is behind the numbers.
