Does this graph accurately indicate overall population density across the map? Or does over-plotting hide the city population densities?

- dj-wonk 12y agoIn theory, I think so: > Each of the 308 million dots are smaller than a pixel on your computer screen at most zoom levels. Therefore, the "smudges" you see at the national and regional levels are actually aggregations of many individual dots. The dots themselves are only resolvable at the city and neighborhood zoom levels. http://www.coopercenter.org/demographics/Racial-Dot-Map#thedots http://www.coopercenter.org/demographics/Racial-Dot-Map#thed... However, it would depend if high levels of smudging max out the color intensity of a pixel. This could be solved with normalization, but I don't know if they did.
