This paper examines the long-term educational benefits to rural youth in China of a major drinking water treatment program started in the 1980s. This health program improved the individuals' education substantially, increasing the grades of education completed by 1.08 years.
- The program benefited girls so much more than boys such that it completely wiped away the gender gap in educational attainment in treated areas of rural China.
- Girls benefited much more from water treatment than boys in schooling attainment.
- Youth with an older brother benefited more than youth with an older sister.
- Boys gained more body mass than girls from having access to treated water.
- Young people that had access to treated plant water in early childhood (0-2 years of age) experienced significantly higher gains in education than those who were exposed to treated water after early childhood.
