Data from a sample of late Middle Archaic sites in west-central Illinois are examined in light of Binford’s forager–collector model. Quantitative methods (correspondence and diversity analyses) are applied to the lithic data from the sites. It is suggested that a mix of mobility strategies was employed in the region during late Middle Archaic. Large, possibly multiseason, valley located residential sites were occupied during the warm season. People occupying such sites were logistically mobile and employed logistical sites to supply some of the resources. In contrast, smaller, upland residential sites were occupied by few people for shorter durations during the cold season. People were residentially mobile while occupying the upland residential sites. The methods demonstrated in the paper are applicable to other regions and time periods.

伊利诺伊州中西部的中古时代晚期聚落系统

根据宾福德的觅食者-收集者模型，对来自伊利诺伊州中西部的中古风晚期遗址样本的数据进行了检查。定量方法（对应性和多样性分析）应用于来自这些地点的岩屑数据。建议在中古时代晚期该地区采用了混合的流动策略。在温暖的季节里，大型的、可能是多季节的、位于山谷的住宅区被占用。占据这些地点的人在后勤上是流动的，并雇用后勤地点来提供一些资源。相比之下，较小的高地住宅区在寒冷季节很少有人居住的时间较短。人们在占领高地住宅区时在住宅区流动。论文中展示的方法适用于其他地区和时间段。
