Oh this is an excellent activity, LoriBeth, thank for getting this started. A few specific resources I found in my pinboard bookmarks, two related to mapping:
Who Maps the World (Bloomberg City/Lab) Do we consider inequities in map making? Answering the title “Too often, men. And money. But a team of OpenStreetMap users is working to draw new cartographic lines, making maps that more accurately—and equitably—reflect our space.” this article describes efforts to collaboratively make maps via OpenStreetMap to make them more equitable.
Inequailgram a project that analyzes millions of images of major cities to understand what they tell us about inequality in places like New York, Bangkok, Sao Paolo, or London. “The inequality of locals’ Instagram sharing turns out to be bigger than inequalities in levels of income, rent, and unemployment. The inequality of visitors’ sharing is larger than income inequality in the most unequal countries.”
And just because I like tracing the origin of things, I loved “The Evolution of an Accidental Meme” the full story by the original artist of the graphic of kids on boxes peering over a fence to see a baseball game, used to demonstrate Equality vs Equity
And also a strong recommendation for the Equity Unbound project http://unboundeq.creativitycourse.org/
