@KirkegaardEmil @skram also you should be able to produce decent correlations within states (w/o having to normalize)

@KirkegaardEmil@skram well the correlation is pretty good in the US, but it's mostly mediated by education level and the like -
@KirkegaardEmil@skram (i mean especially if you aggregate it at geographic level) -

@KirkegaardEmil@skram yeah it's about 0.6 with median income in CA, pretty similar elsewhere -
@KirkegaardEmil@skram of course mean education level and the like also correlate strongly w/ income at that level of aggregation :P
