California Health Interview Survey (CHIS) data from 2003, 2005, 2007 and 2009 on health outcomes were used in the study on which the article is based.

Health outcomes were compared for people living in two hypothetical urban neighborhoods, one with an 18 percent tree canopy and one with a 28 percent tree canopy. Various factors, including income, education, home ownership and race were controlled in order to compare identical populations.

The study estimated that those living in areas with a more expansive tree canopy would have a lower incidence of various health problems: 20 percent lower rates of diabetes and obesity in adults, 23 percent lower rates for being overweight/obese in teens, and 28 percent lower rates of attention deficit hyperactivity disorder in children.
