• Detect additions and subtractions to Florida's state voter rolls.
• Compute demographic statistics on the changes
• Generate CSV output with results

This simple set of code is designed to allow you to determine who has been added or subtracted from Florida's voter rolls by comparing the full list from month to month. But not just all voters, but voters in a variety of demographic groups.

The thing that makes this unique is its ability to analyze the intersectional nature of voters. Want to know how african-american women have been added/removed from voting rolls? You can do that. But to do that, the code has to look at each voter and determine which category (that you have chosen) they fall into.

The list of categories is defined in main.py as the list of filters to use. You can have can abritrary number of filters with arbitrary complexity. There are several examples given in the code to get you started.

Do you wish for different / additional statistics that the filters support but do not know python? Contact me on Twitter at @SocialSeerCom and I'll see what I can do for you.

You can download historical sets of Florida voter lists from here.

The older rolls are conveniently in .zip files so you can download them all at once. The recent ones are not, and you will have to download them one at a time (or figure out how to automate them).

Put each month's data into a separate directory as this program relies on that structure to process the data from each county.

• Detect people who have moved from one county to another. Right now, they are treated as deletions from one county and additions to another.

This is written in python version 3.5, and relies on some features present only in 3.5. Only standard libraries are used at this point.
