According to Amazon's recent annual 10-K filing, the company leased and owned (most of their space is leased) about 288,419,000 square feet of space around the world at the end of 2018. Of this number, about 80% is used for "fulfillment, data centers, and other." Amazon doesn't break out this line item any further, but GeekWire reckons that a good 3/4 of their real estate is dedicated to their fulfillment warehouses.
Here's the full summary of their facilities (from the 10-K filing):

Given that fulfillment is such a large share of their properties, I am most interested in understanding the geography of their warehouses and how that impacts their core value proposition, which is largely all about convenience.
Steven Ballmer – the former CEO of Microsoft and current owner of the LA Clippers – has just launched a website called USAFacts.
He describes it as a 10-K for the US government. Put differently, it is a non-partisan website offering a “data-driven portrait of the American population, our government’s finances, and government’s impact on society.” It provides a complete look at revenue and spending across federal, state, and local governments.
There is no commercial motive behind the website and Ballmer has been quoted in the New York Times saying that he’s “happy to fund the damn thing” whether it ends up being 3, 4, or even 5 million a year.
I love good data and in this current era of “fake news”, I think these sorts of initiatives are exactly what we need.
