After age 85, the U.S. non-Hispanic Black population mortality rate becomes less than that of the White population (called the Black-White mortality crossover). It is not known how this survival advantage compares to Asian and Hispanic groups, and whether differences persist to age 100+ years. ⋯ Race- and ethnicity-based variation in mortality between ages 85 and 100+ years suggests differences in environmental and possibly genetic influences upon risk for exceptional longevity.
