This map marks the areas where people who smoked over 100 cigarettes and still currently smoke (gradient) and shows the concentration of people who have been told by a doctor that they have asthma (dot density) in Queens. Coincidentally, the areas with a higher concentration of dots are generally darker than the areas with a lighter concentration of dots. As asthma can be triggered by environmental factors, living or working an area with a higher incidence of smoking might lead to a greater chance of developing asthma. It is interesting, however, to see that Astoria, an area where power plants spew smoke into the air, is an area where there are not many frequent smokers but has a high concentration of people with asthma.
