What do the towns of Middle Hero, Vermont, Castleton, New York, and Enfield, Massachusetts have in common? They all have voting returns in the New Nation Votes dataset (NNV) and they don’t exist anymore.
NNV contains voting returns at the town, county, and Congressional district level. This geographic information is limited to general place names only (e.g., the town of Suffrage, Otsego County, the tenth Congressional district in New York). Before these locations can be mapped, additional spatial data is needed, such as the latitudes and longitudes of towns or the historic boundaries of counties. Fortunately, there are several spatial datasets that already exist (referenced on our data page) that can be joined to NNV through unique identifiers that we have created. For both the county and Congressional districts, this spatial dataset is sufficient and provides the needed geographic data to map them.
