Initiation
datacatalog.cookcountyil.gov | Last Updated 2024-02-22T17:04:08.000ZThe Initiation results data presented here reflects all of the arrests that came through the door of the State's Attorneys Office (SAO). An initiation is how an arrest turns into a “case” in the courts. Most cases are initiated through a process known as felony review, in which SAO attorneys make a decision whether or not to prosecute. Cases may also be indicted by a grand jury or, in narcotics cases, filed directly by law enforcement (labeled "BOND SET (Narcotics)" in this data). Included in this data set are the defendant counts by initiation and year. This data includes felony cases handled by the Criminal, Narcotics, and Special Prosecution Bureaus. It does not include information about cases processed through the Juvenile Justice and Civil Actions Bureaus.

Assessor [Archived 05-11-2022] - Residential Modeling Characteristics (Chicago)
datacatalog.cookcountyil.gov | Last Updated 2023-05-30T23:49:19.000ZThis data set contains characteristic data points used by the Cook County Assessor in the 2021 Chicago reassessment to produce initial estimates of the current market value of most Chicago homes (single-family homes, small multi-family homes, and condo units). You can use the "Filter" option to search for a property's PIN or address, and see what data the Assessor’s Office had about a home’s characteristics at the time of modeling*. To learn more about how the 2021 model used this data, read about our public <a href="https://gitlab.com/ccao-data-science---modeling/models/ccao_res_avm" target=_new>Residential Automated Valuation Model here</a>. Chicago properties not listed here are reassessed using different modeling procedures. <br> <br> <b>*Important Note:</b> This dataset is, at the time of publication, an early snapshot of data. Data about a home might change later in the assessment process this year as Assessor’s Office staff and analysts review these properties. After this review, updated characteristics and market values are mailed to homeowners. If the data listed on the assessment notice is incorrect, an appeal can be filed to provide the correct characteristics.
