The St. Louis Corridor extending from Chicago, Illinois to St. Louis, Missouri has been described as a “breach” through the Midlands dialect region because of the presence of Inland North features there. Most notably, features associated with the Northern Cities Shift suddenly appeared in Corridor cities in the mid-twentieth century, but they have since largely retreated. Friedman's (2014) population study has uncovered complex relationships between the Corridor's geography and this pattern of advance and retreat, and this work elaborates on that investigation through computational simulations of the Corridor's population structure. Implementing a new network-analytic population model (Kodner & Cerezo Falco, 2018), I find support for Friedman's original hypothesis that migration into cities along Route 66 imported Inland North features into the Corridor first before it spread outward to communities farther away from the route and uncover questions about the Corridor's population that merit further study.

模拟圣路易斯走廊的语言变化

从伊利诺伊州芝加哥延伸到密苏里州圣路易斯的圣路易斯走廊被描述为穿过中部地区方言地区的“突破口”，因为那里存在内陆北部特征。最值得注意的是，与北方城市转移相关的特征在 20 世纪中叶突然出现在走廊城市，但此后它们已基本消退。弗里德曼 (2014) 的人口研究揭示了走廊的地理与这种进退模式之间的复杂关系，这项工作通过对走廊人口结构的计算模拟详细阐述了该调查。实施新的网络分析人口模型（Kodner 和 Cerezo Falco，2018 年），我发现支持弗里德曼的原始假设，即迁移到 66 号公路沿线城市的迁移首先将内陆北部特征引入走廊，然后向外扩散到远离路线的社区，并揭示有关走廊的问题值得进一步研究的人群。
