William Dow and colleague find the poor live longer in Costa Rica than in the U.S.
"The Poorest Americans Die Younger Than the Poorest Costa Ricans" - The Atlantic. 1/4/2016.
Luis Rosero-Bixby and William Dow report a significantly higher age-adjusted mortality rate among the poorest quartile of Americans than their Costa Rican counterparts. They attribute this to more unequal life expectancy outcomes across the economic spectrum in the U.S. than in Costa Rica. Poor Americans under 65 die at a rate 3.4 times higher than their rich counterparts, while that difference is just 1.5 in Costa Rica. The researchers say: “From a life-expectancy standpoint, it is better to live in Costa Rica for low-[income] individuals, whereas it is better to live in the United States for high-[income] people younger than 65.”
