Context There is no story behind this data. These are just supplementary datasets which I plan on using for plotting county wise data on maps.. (in particular for using with my kernel : https://www.kaggle.com/stansilas/maps-are-beautiful-unemployment-is-not/) As that data set didn't have the info I needed for plotting an interactive map using `highcharter` . Content Since I noticed that most demographic datasets here on Kaggle, either have `state code`, `state name`, or `county name + state name` but not all of it i.e county name, fips code, state name + state code. Using these two datasets one can get any combination of state county codes etc. States.csv has State name + code US counties.csv has county wise data.
