    Public Health Birth Data: Infant Mortality

    Metadata Updated: August 23, 2025

    This dataset is part of a series of seven datasets about Cook County births sourced from the Illinois Department of Public Health and curated by the Cook County Department of Public Health. The dataset ranges from 2015 to 2023 and covers all Cook County municipalities except the city of Chicago.

    The datasets are as follows:

    1) Birth and Fertility 2) Birth Outcomes 3) Characteristics of Delivery 4) Infant Mortality 5) Initiated Breastfeeding 6) Pregnancy Health and Risk Factors 7) Sociodemographic Characteristics of Mother

    To maintain confidentiality of individual medical records, counts below 5 and rates below 20 are masked with an asterisk (*).

    Please review values carefully and exercise caution when aggregating. Since the rows overlap across variables and geographic levels, aggregating without filtering will overestimate the counts. For instance, while filtering in "Place" column, not excluding pre-aggregated rows like "Aggregated Region: Suburban Cook County" and "Aggregated Region: CCDPH Jurisdiction" will overstate the counts.
