Density increases walkability, which leads to public health.

Is There a Direct Relation Between Density and Public Health?

//large=bad
density ranked by walkscore cy=(100-walkscore)x20x1.5 (higher more walkable) density ranked by air quality cy=air_rx84 highest-highest(old) (H1-H2)/3 = new difference #x1.36 (higher better healthier) density ranked by cancer cy=cancer_rx50.4 (higher less cancer healthier)
