Georgia ------- Precinct shapefile primarily from the Georgia General Assembly Reapportionment Office (http://www.legis.ga.gov/Joint/reapportionment/en-US/default.aspx). The following counties instead use shapefiles from the U.S. Census Bureau's 2020 Redistricting Data Program Phase 2 release: Clay, Cobb, DeKalb, Gwinnett. Forsyth and Fulton use shapefiles sourced from the respective counties. Three of the four VTDs in Chattahoochee County are comprised of Fort Benning. However, the county only reports one polling location for all voters, including residents of Fort Benning that vote within the county. The four Chattahoochee County VTDs have therefore been merged in the shapefile. The following additional modifications were made to reflect changes made prior to the 2020 general election: Barrow: Merge 2/15, 3/12, 4/14, 5/7, 6/10/13, 8/9, 11/16; Adjust new 2/13 boundary Bartow: Split Cassville/Hamilton Crossing Candler: Merge Candler/Metter as Jack Strickland Comm Center Chatham: Split 7-7/8-16, 7-12/7-16; Realign 7-06C/7-07C Chatooga: Cloudland/Teloga split along the ridgeline that marks the boundary between them with the USGS Topographic Contour shapefile Clayton: Split Ellenswood 1/2, Jonesboro 1/17/19, Lovejoy 3/6/7, Morrow 3/11, 5/10, Oak 3/5 Cobb: Split Bells Ferry 3/4, Dobbins 1/2, Marietta 3A/3B, Smyrna 3A/3B Columbia: Split Bessie Thomas/2nd Mt Moriah, Harlem Branch/Harlem Senior Ctr; Merge Blanchard Park/MTZ Col FD; Align multiple precincts with county maps Coweta: Merge Arts Centre/Jefferson Parkway as Newnan Centre DeKalb: Split Clarkston/Clarkston Comm Ctr; Realign Decatur/Oakhurst; Align precincts with Atlanta, Brookhaven, Decatur, Tucker city limits Gwinnett: Adjust Baycreek F/G, Berkshire J/M, Cates D/F, Garners C/B, Lawrenceville G/N, Pinckneyville S/T, Rockbridge A/G Lowndes: Split Northgate Assembly/Trinity, Jaycee/Mt Calvary/Northside/VSU Oconee: Merge Annex/City Hall; Align City Hall with Watkinsville city limits Paulding: Reorganize 12 precincts into 19 precincts as redrawn in 2019 Randolph: Merge Carnegie/Cuthbert-Courthouse, 4th District/Fountain Bridge/Shellman Troup: Split Mountville between Gardner Newman/Hogansville/Rosemont; Align multiple precincts with county maps Towns: Merge Macedonia/Tate City Iowa ---- Precinct shapefile primarily from IA Secretary of State: https://sos.iowa.gov/shapefiles/ The following counties used shapefiles sourced from the respective county governments instead: Dallas, Johnson, Linn, Story.

The new twelve precinct map has been approved by the IA Secretary of State and is expected to receive a final vote by the county Board of Supervisors on January 28. The Democratic Party has consequently designated caucus locations based on the new precinct boundaries. The shapefile was revised accordingly using the proposed map provided by the Mitchell County Auditor and the legal description of the precincts filed with the IA Secretary of State. Nevada ------ Caucus locations from Nevada State Democratic Party (https://nvdems.com/caucus-day-locations/) Precinct shapefiles primarily from the U.S. Census Bureau's 2020 Redistricting Data Program Phase 2 release. The following counties used shapefiles sourced from the respective county governments instead: Clark, Douglas, Elko, Humboldt, Lincoln, Lyon, Washoe. County borders in all county-sourced shapefiles were aligned to the U.S Census Bureau's boundaries. Minor adjustments were made in the Precinct 1/3 boundary of Eureka County and in the Precinct 6/5 boundary of Pershing County to match county GIS maps. Substantial revisions were made in the Fallon area of Churchill County and in the Tonopah area of Nye County to match county PDF maps. The sites for the Strip caucuses in Las Vegas were added from the Clark County parcel shapefile. Note that Clark County and Washoe County routinely alter precincts between the primary election and the general election when necessary to reflect municipal annexations. New Hampshire ------------- Precinct shapefile from the U.S. Census Bureau's 2020 Redistricting Data Program Phase 2 release. The Census VTD shapefile includes wards for the Town of Berlin and the Town of Derry that are only used for municipal elections. These were merged to match the statewide election returns. The wards for the Town of Laconia were revised to match the 2012 municipal redistricting map.
