Abstract: | The challenges of understanding gerrymandering are primarily related to its conceptual ambiguity and measurement. This is true despite landmark legal rulings and a rich literature on the subject. In an attempt to alleviate some of the confusion, theories of the gerrymandering process are combined with advanced quantitative and mapping techniques. The focus is on Chicago, where it is frequently claimed that gerrymandering is institutionalised; however, there has not been sufficient study of the causal connections between gerrymandering and a ward’s racial makeup. Employing a mixed methods approach which combines a case study of the 2011–2012 redistricting in Chicago with quantitative analysis of Decennial Census and data from the Chicago Data Portal, this article examines the remapping of Chicago from early 2012 (effective in 2015 and matched with 2010 Census data) to assess how potentially gerrymandered districts are diluting or concentrating vote share of racially homogeneous groups. |
