At least two counties changed in some way between 20.US Census Departmentshapefiles do use leading zeroes. These FIPS codes are formatted without leading zeroes.I do notyet know where to find vote totals by borough. Alaskaofficially reports vote totals by state house district, not borough. The Guardian data does not list individual boroughs in Alaska.Iran some basic sanity checks and corrected the errors I found, but I can'tguarantee that the data is completely free of mistakes. I had to enter some of this information manually or using ad hoc scripts.

However, the vote totals doinclude all candidates.

Since each state had different third-party candidates on the ballot,and tabulated the results differently, tracking them individually would havetaken additional time that I chose not to invest.

I have not been able to obtain year-by-year county-level data on the proportionof noncitizens and disenfranchised felons.
