It's been years since I read it, but I recall Poor Economics (https://www.amazon.com/Poor-Economics-audiobook/dp/B006ST3XTW/ref=sr_1_4?dchild=1&qid=1625123657&refinements=p_27%3AEsther+Duflo&s=books&sr=1-4) providing significant insight on life at lower levels of income; I think it was probably also informative about the median case.
If a whole book is too much, you could also try their article, Economic Lives of the Poor - https://www.aeaweb.org/articles?id=10.1257/jep.21.1.141 - but this is explicitly focused on people living below the extreme poverty line, who are an order of magnitude poorer than the global median.
I recently learned from the Key EA Numbers Anki deck that median household income is Int$2,835, or $236 per month (methodology). I'm interested in some slice-of-life data about people earning about that much money. Imagine answering these questions for common archetypes of people at that income. If I imagine myself living at that income:
That's a lot of questions that might be difficult to answer, so definitely answer even if you only have information about one. I'm sure I'm curious about more than just those questions — I'd be happy if the comments were filled with all sorts of random related information.
Dollar Street is great for visualizing this!
Here's a family in Jordan with a monthly income of $249: https://www.gapminder.org/dollar-street?active=5fd03b43f2d9500e4358f313
And a family in the Philippines who earn $238 per month: https://www.gapminder.org/dollar-street?min=169&max=285&active=5fd043b2f2d9500e435926ea
Thanks! That's very much the sort of thing that's helpful.
