A special note about crime data. Chicago Cityscape doesn't show or have data about reported crimes: it is very biased as many communities are overpoliced, often represents alleged and unconfirmed crimes, poorly represents actual threats or danger, has sometimes been published with errors or is amended later; and, when mapped, crime data can imply "hotspots" that are based on temporary and contextual situations rather than geographical (place-based) factors. Further reading about crime data and bias; Injustice Watch and Invisible Institute are local resources to learn about overpolicing, police misconduct, and the use of data and person-tracking databases.
