    Public Health Birth Data: Infant Mortality

    Metadata Updated: February 1, 2026

    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. This dataset includes infant mortality counts and rates across the County (excluding Chicago).

    The full data series is 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 metadata and values carefully and exercise caution when aggregating. Some columns only contain data across certain age groups. Some rows overlap across variables and geographic levels and aggregating without filtering may overestimate the counts. For example, aggregating counts across Place without excluding pre-aggregated counts for "Aggregated Region: Suburban Cook County" and "Aggregated Region: CCDPH Jurisdiction" will overstate the counts.

    Data prior to 2015 can be found here: Suburban Cook County Births (2000-2014)
