I quibble with the description of the shapes bounded by 10 degrees of longitude and latitude as "rectangles" - they're not even planar shapes, and their adjacent sides certainly aren't at right angles. Some of them don't even have four sides. This bears considering when looking at the map, because some of those regions are much, much smaller than others.

A lot of comments about metros areas and the like, such as how Jacksonville shows up because of city limits being larger than atlanta, but if you start getting I to trying to define what a city's metro area is, you run into a lot of issues with giant powerful cities like NY. Can you really count the population of Newark, New Jersey as part of NYC, NY? Even though newark is firmly within the NYC metro area, it's a sep…

Jacksonville is the largest U.S. city by area, in the contiguous 48 states.

Alaska has several cities with enormous boundaries.

I'm currently working on a project that involves dataviz & mapping, and one of the things I've discovered along the way was WikiData's SPARQL query engine.

Mind = blown.

You can basically ask Wiki(pedia) almost anything you can think of (including the largest city in a bounding box) using the same query language.

Examples:

- Largest cities per country (https://w.wiki/UC4)

- Cities connected by the European route E40 (https://w.wiki/74E)

- Streets in France named after a woman (https://w.wiki/34K)

Earlier quoted context omitted.

Chicago is having significant population loss, so that gap will only grow. I believe Houston is about to pass Chicago.

Why is Chicago losing people?

The city is losing people, the suburbs (particularly the outer ones) are not. Chicagoland is still growing.

Maybe the author should have gone with the faces of a Disdyakis triacontahedron

That's handy! To be honest, SPARQL is definitely not easy to use.

Well it lends to an aliasing effect, that in Europe is even more comical. You completely lose the major cities of most countries like Ireland, Sweden, Denmark, and Poland. Central Europe is blotted out by Rome. The Romans finally conquer (most of) Germany. ;)
