Below are the preliminary results from performing exact (string distance of 0) duplicate record checks on the 2023-07-01 VA Registered Voter List information. Note that these are the numbers of ordered matches discovered, not the number of individual unique registrants. Each count represents two different registration records, with unique voter IDs, that match the given criteria. Match pairs are directional, in that a pair (A,B) is counted separately from the pair (B, A). Matches are grouped into this table according to the LOCALITY_NAME of the first element of the identified pair. Some pairs can have different locality information, except for in the strictest case (3rd column), so a match might be counted in one locality while its mirror is counted in the other.
The first data column of the table below is equivalent to the criteria used by the MOU between the VA Department of Elections (ELECT) and the Department of Motor Vehicles (DMV), as discussed and documented in a previous post. There were 5,290 matches for this criteria across the state.
The second data column below is based on a match of the registrants Full Name and Day+Month+Year of birth information, but NOT the registrants listed address information. There were 1,200 matches for this criteria across the state.
The third data column is the strictest match criteria and includes the Gender and Address of the registrant. There were 208 matches for this criteria across the state.
I am only considering Active registrations in the table below. I previously computed similar statistics using the previous purchased 2022-11-23 RVL, I have not yet done a comparison of the two datasets, but will do so once I complete the string distance processing on this latest set.
