This region is massively populated, due to a few factors:
- The Northeastern Sprawl was already fucking huge
- Massive cities were submerged, in particular NYC and Montreal
- Toronto Free State may have had some character that drove people out when it became a city-state [not determined yet]
- Minneapolis Motor Syndicate is offensive to anyone not a Nazi, and they're not gonna emigrate West; Chicago may have been too exclusive for some emigrants who didn't want to risk the chaos of the public Arcologies. For many, immigration to the Dearborn Caliphate was not an option.
- Republic of New England pursued more sustainable goals whereas this state continues to pursue commerce at all costs; the other options were Quebec or Canada.
- Confederation of Carolina is likely culturally inimical to Northeasterners, given its racial-panic origins; Spanish Coast may have been culturally alien to people with a choice to emigrate North or South.
