The Data

We retrieve case records from the 36th District Court’s online Register of Actions (ROA) case inquiry system and partner with Data Driven Detroit (D3) to translate case-level information into a quantitative dataset.

We link eviction records to property assessor and Certificate of Compliance data from the City of Detroit Open Data Portal.

We define residential properties based on assessor class and use codes and exclude cases where the defendant name indicates an LLC or other business. To include mixed-used multi-unit buildings that may be coded commercially, we use a dataset of multi-family properties compiled by students at the University of Michigan Dearborn.

We analyze outcomes (e.g., judgments, orders of eviction) by case, not individual defendants.

We include cases brought against the same tenant and/or address on different dates.

To ensure the highest possible data quality, we confirm random samples of case records manually.

We cannot account for court-recorded errors or records entered after the case record is retrieved.
