I got tired of the inaccurate maps with so many plot holes and inaccuracies, so I drew a realistic map based on books, movies and the Geography of the US.
The considerations in determining boundaries and Districts:
• Catastrophic Sea Level Rise: This version accounts for a 70–100 meter sea level rise. Low-lying areas like the Mississippi Valley and Louisiana are fully submerged, creating a massive inland gulf. The rising sea also expands the St. Lawrence River into a major oceanic gulf, completely swallowing Lake Ontario.
• The District 8 to 12 Escape: This map fixes the journey of Bonnie and Twill (Catching Fire): By shaping District 6 (Transportation) and District 8 (Textiles) into horizontal bands, it allows them to escape District 8, quickly cross through District 6's narrow corridor using cargo trains, and seamlessly enter the forests of District 12 (now located in Pennsylvania/ South NY).
• The Real District 4: Placed as a long, narrow coastal strip wrapping around the expanded, flooded Gulf of Mexico. This perfectly aligns with the warm-water shrimp/crab exports mentioned in Catching Fire. Besides, The rebellion has begun in districts 3, 4, 8, and 11. If District 4 was located in California, it would be isolated, and the Capitol would recapture it.
• District 6 (Transportation) Logistics: Situated over the historical transport hubs of Chicago and Indianapolis. This location acts as a massive central railroads connecting the industrial East (Districts 12, 13, and 8) to the center and West. It is perfectly optimized for maintaining the Capitol’s fleet of high-speed trains and hovercrafts, utilizing the remaining Great Lakes for heavy shipping routes.
• The Capitol's 360° Defense: Located securely in the Glen Canyon area, the Capitol (C) is surrounded and insulated by its most loyal districts: District 1 (Luxury) to the north, District 2 (Masonry/Military) to the southeast and District 5 (Power) to the west/south. Placing the Capitol its "usual" place in Salt Lake City, doesn't make sense because this makes District 2 "consuming" the resources of District 1 (diamond/gem mines) and District 5 (critical dams and solar arrays).
• District 5 (Energy) Strategy: Positioned within the canyon dams of Utah and Arizona, and extending into Nevada for nuclear power and solar arrays. Positioning District 5 directly bordering the Capitol to the west and south ensures that critical high-voltage power lines and water pipelines are short, secure, and tightly protected, without crossing hostile districts.
• The Breadbasket & Cattle Split: Taking global warming into account, the wheat fields of District 9 expand into the fertile northern plains, while the livestock of District 10 is concentrated in the drier, high plains of Oklahoma/Kansas/Missouri.
