Maps and data frequently asked questions

Where did you acquire the eviction data you use in your study?


The eviction data we use was acquired directly from the Iowa Judicial Branch, which maintains a statewide record of all eviction cases that are submitted to local courts. Due to privacy rules, the Judicial Branch did not provide dwelling unit address information. You can reference our Methods section for a more detailed outline on our data collection process.




How do I use the map and what is the information displayed on the map?


The map consists of multiple layers of data, which you can select or deselect based on what other variables and features you want to display alongside the eviction data. The data displayed in the map includes eviction cases for 26 Iowa Counties from January 2010 - March 2021.




What do the different markers on the map represent?


Each marker on the map represents eviction cases within a zip code area. If you click on a marker, you will get additional information about the number of eviction cases filed in a zip code area. When you select a marker on the map, you can get additional details about individual eviction cases by clicking on the right-hand arrow displayed on the blue pop-up box. You can also display demographic information from the American Community Survey on the map.




Why are there eviction cases showing outside a county boundry?


There were instances where a defendant moved since the filing of the court case and may have been involved in subsequent court matters. In such instances, the court would have an updated address for the defendant. Therefore, the eviction cases that show outside of the boundaries of a particular county reflect the number of eviction cases we did not have enough information on to confirm the zipcode of the defendant at the time the eviction case was filed (of the unit a landlord was evicting them from). For example, a landlord filed an eviction case for a unit located in Des Moines (Polk). The tenant has moved since the original eviction case filing to Waterloo (Black Hawk) and their address (zip code) has been updated in court system. While this eviction filing case would be counted in Polk records, the location of the case may appear in Waterloo.
