Residential Segregation - Real estate agents would raise prices on their neighborhood houses whenever a Mexican immigrant would be searching for a house. Because they could not afford it, they then had to move to a more far away trailer that was cheaper. This meant that many of the immigrants lived in the outskirts of Postville, together, rather than closer to the locals.
Succession - The Hasidic Jews and Mexican immigrants took over Postville, creating and working in their own meat plants and even requiring teachers to teach English to the immigrant's children. Yep. The amount of non-English speakers in small-town Iowa required the schools to teach them the language.
