It's hard to find data on this is general. I've seen a couple maps before of counties within states, and their state-level spending/revenue, but finding the same for counties when it comes to federal revenue...never seen anything like that.
edit: I mean a map similar to this - https://streets.mn/2015/01/14/map-of-the-day-state-highway-t...
Though it should really be a percentage-based map using population size, rather than using absolute amounts.
edit2: ah, this is pretty decent, even though it's not a map - https://ofm.wa.gov/sites/default/files/public/dataresearch/f...
As you can see here, King County (Seattle and nearby suburbs) sends way more to the state in revenue than it gets in spending. Most of the other counties -- which are obviously low population -- receive more in spending than revenue. In other words, they're subsidized. From what I understand, this is pretty common within states.
