This project examines school absence data in the twin cities of Champaign and Urbana during the 2009 H1N1 pandemic. These school districts differ in their catchment policies with Urbana using traditional neighborhood schools and Champaign schools being integrated city-wide. Analysis of these data showed that there is a difference both in time and severity between the two school districts. Urbana schools show a distinct time of increased absences over the course of October 2009, while Champaign schools show a general peak in absences in mid-October. There were no significant correlations among absences and low-income composition, school population, or ethnic composition.
