How do I teach about inequity in computing resources? What activities, and with what resources, are effective for students to learn about the status and consequences of inequities in computing resources? 

Activities could address inequities within a community or across the globe.

Background:
The Advanced Placement™ CS Principles course has two "essential knowledge" (EK) statements related to this topic:


EK 7.4.1C The global distribution of computing resources raises issues of equity, access, and power.
EK 7.4.1D Groups and individuals are affected by the "digital divide" - differing access to computing and the Internet based on socioeconomic or geographic characteristics.


The AP framework indicates these objectives should be associated in the classroom with the computational thinking practice of "connecting computing" by finding ties among computing concepts, impacts of computing, and connections between people and computing. My question is not necessarily constrained that way, though it seems inherent in achieving the objective.

(I came across a resource on this topic that I wanted to share. A related question here did not exist, so I intend to share the resource in an answer but not to imply that the resource or lesson format I share is the best one. Please share other resources and lesson formats!)
This seems to me to be the sort of topic that is best covered with an assignment such as
Write a paper, citing resources, on the topic of XYZ.
There are a number of other things that can be addressed this way. One advantage of such an assignment is that students have to write using natural language, which often gets too little attention in technical fields.
Another advantage is that you can have the work done in pairs or teams.
Another advantage is that you can follow up with class discussion, seeking consensus on the problem.
You can, of course, provide them with an initial set of resources so that they are forced to look beyond Wikipedia and other easily found resources.
You can also ask for critique of the resources that they find, not just reporting. You can even have a debate. Lots of possibilities since the topic is both serious and open ended.
