The Core

Bricks retail is mortally wounded.  Other than groceries, cafes, restaurants, & large furniture, I can't recall purchasing more than $200 of products in stores in all of 2019.   

BTW, I was just reading about the old Blockbusters chain.   4500+ retail stores now gone.  Streaming is a bricks killer, too.

It's like a rough map of US population density. No surprise there.

But what jumps out is that it's also a rough map of areas that vote democratic. Some of that is obvious (California) and some of it is not (Texas). But overlay a map of Texas voting patterns over the Amazon map

If you're in a Democratic district in Texas, you probably have an Amazon warehouse close to you. I live in a very Republican district in California and Amazon does NOT offer next day delivery in our region. We have no carrier that offers overnight delivery of anything unless you pay for a high-priced courrier (at the hotel, a prince of Dubai recently had a case of his favorite wine delivered by courrier and, later, MacDonald's meals). My niece lives in Brooklyn. She gets same-day delivery of tons of stuff.

It suddenly strikes me that what party you vote for is somewhat predictive of how likely you are to be able to get next-day delivery of a given Amazon item...

I wonder how many other US cultural maps overlay with that. It maps pretty well with education

If you have a college degree, you are more likely to be eligible for next day Amazon delivery.

I realize the last two (college and political party) are mostly artifacts of population density, which is what really explains the location of the warehouses. Still, I find it interesting as just one more measure of the Big Sort. Of course, not everyone buys the Big Sort argument
