Asthma and Air Pollution in Baltimore City

This report documents stark differences in asthma hospitalization rates in rich versus poor neighborhoods in Baltimore, and reveals a dramatic drop in the far southern part of the city after a pair of nearby coal-fired power plants installed air pollution control devices in 2009.

Asthma hospitalization rates in the zip codes for the Cherry Hill, Brooklyn, and Curtis Bay neighborhoods fell 57 percent between 2009 and 2013 – more than twice the drop citywide – after a state law compelled the nearby Brandon Shores and Wagner power plants to install major new pollution control systems.
