Searching for the densest square kilometer in different cities

Based on data from Gridded Population of the World, geographer Garrett Dash Nelson calculated the square kilometers in major cities with the highest population density.

On CityLab:

In the interactive visualization, I’ve taken GPW data for a curated selection of American cities. Some have old, historic cores, and others are dominated by more recent development; some have constricting physical geographies and others lie on relatively flat, open plains; some were built for horse transportation and others for the automobile era.

Equal population mapper

Equal population mapper

We know that there are more people per square mile in some places than others, but it can be a challenge to understand the magnitude of the differences. The same goes for the other way around. So Ben Blatt for Slate made the Equal Population Mapper, which lets you select an area of interest such as Los Angeles county or the state of Wyoming and see how many counties it takes to equal the population of said area.

For example, the above shows coastal counties as the point of reference, and you see the counties it takes to equal the coastal population in red. That's a big section in the middle.

Might remind you of the Per Square Mile project from a while back which used cities around the world as point of reference and US states as the mode of comparison.
