I'm looking for long lists of structured demographic, economic, agricultural and/or geographic attributes of US States. For example:
<geo name="Iowa" population=3107000 cows_per_capita=1.2* etc=...>
<geo name="Connecticut" population=3597000 cows_per_capita=0.2* etc=...>
*Cows_per_capita are my estimates
A great source would be the CIA Factbook (i.e. US), but I don't know where analogous attributes can be found for individual States (also, it's only really structured by 3rd parties - example).
I feel like Wikidata would be also good source, but it seems the attribute lists are limited to qualitative data.
Formats: Appreciated formats are CSV, JSON, XML, .SQL, and even XLS/ODS files.
License: it's for non-commercial use and I'll give plenty of attribution
