#Cartogram
The election is coming... time to get maps ready! We have both normal maps and our hexmap cartogram available for you as image files, shapefiles, and svg files.

The cartogram can also be found on Datawrapper under USA>>Congressional Districts Elections 2026 (hexmap)

it'd be cool to see a cartogram like that but morphed over time throughout the war to pick up changes like aircraft production in California.

All it could take for the national popular vote compact to reach a majority of electoral votes is for Democrats to flip six legislative chambers across Arizona, Michigan, Pennsylvania, and Wisconsin:

Maybe this is not done because they look kind of ugly. Still seems moderately useful, though.

A cartogram is a map distorted to be proportional to some property, such as population density. Why don't we use them in oceanography? I've never seen one even for primary productivity, which is concentrated around coasts.

Where Brazil lives. The North is 45% of the land but 9% of the people; the Southeast is 11% of the land and 42% of the people. Equal-area blocks on the real terrain reflow to one block per 250,000 people.

Maybe we can create a cartogram-map of the W Social users (now, or after the official launch)?

I'll put a more detailed version of this in this week's Poll-Free Calls write-up, but I made a House district cartogram in Google Sheets and color-coded it by how much of the national popular vote shift each district will absorb. Anything orange is below the overall shift, anything green is above

messing with animations for my maps and have a fun factoid for you all: for much of the day, people in Bern (urban population approx 130k) can access more people within one hour of travel by public transport - they can get to 19 million people - than people in Paris […]

Texas, using our 100K Districts and Tabula America Index, but with 2 different shapes. The left is the districts as they normally look, but the right is a cartogram, so every district (of 100,000 people) is the same size.

100K Districts on Tabula America Genus that:

-Are majority-minority
-Are in the bottom 25% percentile in income

In our Cartogram view!

There are areas that had huge swings to Trump in 24, and areas that may swing back hardest to Dems.

Cartogram observations:
As far as I can tell, of no-coding-required tools only ArcGIS supports Dorling cartograms out of the box, which is odd? Datawrapper has cartograms for the world, US states and German states.

Fun aside: Danny Dorling was only 28 when he published the algorithm in 1996.

should probably show all public transport vs just train-like (including ferries which are honorary trains) and the cartograms too

Kudos to the United Nations for doing something in cartography that should’ve been embraced 50 years ago.

Now it’s time to embrace the cartogram over choropleth. Do it cowards.

Correct-area maps do nothing to solve the problem that big deserted areas like most of Canada, Siberia and Australia completely overwhelm small areas where a lot of people live like Netherlands and Bangladesh. For any form of people-related choropleth, a population cartogram is the only way.

I think a more interesting map is @electioncord.com 100K districts where Dem votes went down by 1,000 or more from 2016 to 2024. Mapped in cartogram so you can actually figure out where they are.

Here you see a lot more urban areas, just a catastrophic relative turnout/persuasion collapse.

But yeah, my cartogram and old Google Map proposal have diverged, so I deleted. Maybe I'm tired too?

Regardless: Sunset south of park 34 north of park. It's been a few years since I thought about precise alignments beyond "cover the West Side well"

Cool -- I don't think I've seen a population cartogram for Japan before.
Population of Japan Visualized

Each square represents 0.1% of the county's population with the 10 biggest Urban areas (with cities) in a lighter color.

A cartogram resizes countries by population instead of land area, using a 2004 PNAS diffusion algorithm: population acts like a gas spreading to even density, dragging borders along.

A small, crowded country can end up looking bigger than a much larger, emptier one.
