On January 1,2004, it became mandatory for all police departments in Illinois to record data pertaining to race from every traffic stop. Mundelein, Illinois, has been collecting data since 2000. Rather than using census data to determine the racial distribution of the village, they thought it better to use data based on who is using the roads in Mundelein. So they collected data on at-fault drivers involved in car accidents in the village (the implicit assumption here is that race Is independent of fault in a crash) and obtained the following distribution of race for users of roads in Mundelein.
