The places in the United States with the highest populations weren’t always like that. There were shifts over decades. With the recent Census release for state populations, Harry Stevens and Nick Kirkpatrick for The Washington Post go all in with a series of bump charts to show the changes in state population rankings since 1920.
They point out historical markers along the way, split it up by region, and provide an explorer at the end to look at your states of interest. In the end, it all comes down to weather and air conditioning.
Still deciding what I think about those gradient connections.

You’ve probably seen the composite map of lights at night from NASA. It looks a lot like population density. Tim Wallace adjusted the map for population, so that you can see (roughly) the areas that produce more light per person.

How many US cities can you name? Here’s a quick and fun game by Ian Fisher to find out. Simply start entering as many as you can think of and rack up population counts as a sort of point system.

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.
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.

You’ve seen the maps of population density. You’ve seen the jokes. But you haven’t seen population at high granularity in a 3-D view. Matt Daniels for The Pudding used a mountain metaphor to show the peaks and valleys of population around the world.
You get more out of the data in this view than you would the overhead, which tends to obscure the variation in large cities. Although if you must, Daniels also provides the typical view to reference.

Population data typically comes in the context of boundaries. City data. County data. Country data. With their Population Estimate Service, NASA provides data at higher granularity. You can request estimated population in the context of a world grid.
Here’s an interactive map to demonstrate the API. Click and drag a shape across any region in the world and get an estimate of the population within that shape. [via kottke]

We saw the changing percentage of white people in the United States and how whites are not the majority in a lot of places. Who is the majority in these areas? Here’s a breakdown for the main three races that make up majorities.

Below is the estimated percentage of white population in the United States from 1970 to 2010, based on data from the Census Bureau and made more accessible by NHGIS. I like the evaporative quality coming up in the southwest.
Mostly though, this is just me trying out a new toy, and the form fascinates me at the moment.
Members: I’m working on a set of tutorials for how to make these. There are a few steps involved, so I’m breaking it down to make it more digestible. Part 1 is here.

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.
