Injustice Watch, a nonprofit newsroom investigating the Cook County (Chicago) courts system, used Geocodio to clean up 2.3M messy, incomplete, and misspelled address records in their "Tenant Trap" investigation. "To examine the link between dangerous building disrepair and evictions in Chicago, Injustice Watch analyzed roughly 1.9 million code violations, 60,000 administrative court dockets, 300,000 eviction court dockets, and 43,000 housing court dockets dating back to the early 2000s. Building violations and administrative hearings clearly identify the offending address, while location information from eviction records is based on the defendant’s address in each case.
