About 25% of ZIP codes don't have a corresponding Census Bureau ZCTA, for example 10118. Do you end up needing special handling for those cases? Or has it not yet come up in practice?

The overall claim is true - yes put it on a map.

But I'm not a fan of these particular maps because the use of 3d makes them harder to read. The isometric view and rotation away from north at the top break conventions that people use to orient themselves in the map and connect it to their lived experiences on the ground. I'm reasonably familiar with NYC geography, and I could not immediately recognize the landscape I was looking at in these maps. Ironically, it was only because I already knew the answer to the question that I could do so: "oh that huge green spike must be Manhattan".

I think a 2d choropleth map with a diverging color scale centered on the mean value would work better.

At 1km resolution, this is largely just a map of US urbanized areas. The spatial variation isn't that interesting. The temporal variation and the absolute values per spatial unit are the greater value of this project.

I think adding something like (or awareness of datum transformations generally) would make the tool harder to use for its intended audience. If you need the level of precision where tectonic plate movement matters, then you need professional level tools.

What are the masculine-coded virtues?

Strength. A man's vehicle should both demonstrate and develop his physical prowess.

Protection. A man's vehicle should make others safer, even if it puts himself at greater risk.

Providing. A man should buy the cheapest vehicle that serves his needs, the better to provide for his family.

A cargo bike is the manliest vehicle you can use.

My experience has been that data generalists should stay away from geospatial analysis precisely because they lack a full appreciation of the importance of spatial references. I've seen people fail at this task in so many ways. From "I don't need a library to reproject, I'll just use a haversine function" to "I'll just do a spatial join of these address points in WGS84 to these parcels in NAD27" to "these North Korean missiles aren't a threat because according to this map using a Mercator projection, we are out of range."

DuckDB is great, but the fact that it makes it easier for data generalists to make mistakes with geospatial data is mark against it, not in its favor.

Squares have a contiguity problem: does a square in a grid have 4 neighbors (rook contiguity) or 8 (queen contiguity)? Hexagons do not have this problem. All neighbors of a hexagon share a full edge, not just a vertex. All neighbors of a hex also have their centers equidistant from that hex. A massive number of spatial problems turn on neighborhood definitions, and hexes are almost always a better representation of reality than squares.

I work for a federal defense contractor that is required to prove in Department of Labor audits that pay is not discriminatory. The possibility of losing those federal contracts is an existential threat to the company. Definitely not "niche cherry picked reporting stats that few people look at."

The significant restructuring (affected several hundred people) that you describe did in fact occur.

Considering that the company I work for tried to hide their gender pay discrimination by "releveling" all the women who were getting systematically underpaid, you should in fact report these data without disaggregation.

"Those people make less because they are all lower level" is not a mitigating factor for pay discrimination.
