20 Dec 2017 --- Opening a new supermarket in a low-income neighborhood may improve residents' economic well-being and health, even if residents don't necessarily buy healthier food from the store, according to a new RAND Corporation study. The researchers studied a low-income neighborhood in Pittsburgh, Pennsylvania, where a new supermarket opened after decades of absence, and found that residents reported improvements across a number of economic and health benchmarks a year after the store opened, as compared to residents of a similar neighborhood that did not have a supermarket.
