Objective To examine the relationship between race and lung cancer mortality and the effect of residential segregation in the United States.
Design A retrospective, population-based study using data obtained from the 2009 Area Resource File and Surveillance, Epidemiology and End Results program.
Setting Each county in the United States.
Patients Black and white populations per US county.

The score ranges from 0 to 100 in increasing degrees of residential segregation. Read more
