Guided Mississippi Election Playbooks (Zero-PII)

Identifies addresses with 8+ registered voters while separating 58 nursing homes/universities/military hubs and 122 apartment complexes from 2,269 single-family homes.

Uses whole-word regex matching to flag communal buildings missing room/apt numbers—eliminating 4,346 false alarms on streets like Marshall Pl and Halls Ferry Rd.

Flags 380 records where a P.O. Box or Private Mail Box was typed into the physical residential line instead of the mailing address field.

Isolates 1,011 active registrations containing rural highway or descriptive text in their street address without a structured house number needed for E-911 GIS parcel verification.

Isolates 2,444 Active voters receiving mail out-of-state from the 11,178 already moved to Inactive status awaiting their 2-cycle NVRA removal period.

Identifies 5,607 legacy paper-to-digital database migration placeholders (such as 1900, 1801, 0001, or DATAMIGRATION street strings) and 1-letter truncated name initials.

Protects 6,146 Jr./Sr./III father-son family pairs while isolating 1,249 Active–Active intra-ZIP duplicate clusters and 261 Active–Inactive move trails.

Non-partisan dual check: (1) Voter Protection — flags 36,071 voters marked Inactive despite casting a 2024–2026 ballot; (2) List Maintenance — flags 196,957 Active voters registered <= 2018 with no vote recorded since before 2018.

Maps single-day registration spikes against Mississippi's statutory registration cutoff dates prior to Presidential General Elections.

Flags 123 polling places exceeding the 3,000-voter EAC benchmark (27 exceeding 5,000 voters) and 11 records with blank precinct codes.

Tests precinct registration (χ² = 9.16) and 2024 turnout (χ² = 30.12) against Benford's first-digit distribution across all 1,742 precincts.

Joins all 25,911,769 historical ballots against the Mississippi Voter Roll with zero orphaned rows and isolates duplicate same-day primary scan lines.

Coalesces County Supervisor District across SUPR and Panola County's SUP column (eliminating 24,013 false alarms) and isolates the 7 active voters statewide missing a Supervisor/EC district.

Identifies 356 polling places that span multiple Congressional (3), State Senate (96), or State House (308) districts so County Election Commissioners can verify 911 GIS street-range ballot styles.
