Grist, February 20, 2017: Nearly 8,000 U.S. public schools are plagued by toxic air
“Though minority and white students are equally likely to attend public schools in suburbs, where about 2,600 schools lie near busy roads, there’s an urban-rural divide. Minority students are much more likely than white students to attend public school in big cities, which account for nearly 3,000 schools near such roads. And they’re a lot less likely than white students to attend class in rural areas, where traffic is generally lighter. Big cities serve a higher percentage of low-income students, too.”
