WISH Query: Infant Mortality Module

(Data updated September 2021)

You can use this module to analyze key statistics about Wisconsin infant deaths: the number of deaths, the overall infant mortality rate, and the neonatal and postneonatal mortality rates. Wisconsin infant deaths are those that occur to Wisconsin residents before the age of one.

This revision adds 2019 and 2020 birth and infant mortality data to the module.

Follow the seven steps below to design a table that focuses on specific causes of death, maternal and infant characteristics, and/or aspects of prenatal and delivery care. You can select or compare data for specific counties, local health departments, cities, or Milwaukee ZIP codes. The data are from 1990 through 2020; you can choose one year, combine years, or compare groups of years.

Definitions and notes on these measures are in Measures Used in Birth Modules.

Step 1. Which measure do you wish to focus on?


Note: The mortality rate is the number of infant, neonatal, or postneonatal deaths in a year per 1,000 births in the same year.

Step 2. Choose One or More Geographic Areas

You can ask for data for the entire state of Wisconsin or for smaller geographic areas. All locations refer to residence of:

State: Click the "Wisconsin statewide" button (the default option).
Region: Click the "Region" button. Then select one region, or hold down the Control (Ctrl) key and select multiple regions.
County: Click the "County" button. Then select one county, or hold down the Control (Ctrl) key and select multiple counties.
City: Click the "City" button. Then select one city name, or hold down the Control (Ctrl) key and select multiple cities.
Milwaukee: Click the "City of Milwaukee" button. Then click one of the ZIP codes, or hold down the Control (Ctrl) key and select multiple ZIP codes.
Local Health Department: Click the "Local Health Department" button. Then select one health department, or hold down the Control (Ctrl) key and select multiple health departments.

Note: To see results for individual areas, first select the areas of interest here, then choose "Geographic Area" as a ROW or COLUMN variable in Step 6 or 7 below.

Step 3. Choose One or More Years

You can see data for the latest available year (2020). Or you can choose to see one or more single years, or one or more groups of years. If you are requesting data for an area or group with few annual births, it may be useful to combine years of data. WISH suppresses small numbers (cell size less than 5) to comply with Wisconsin vital records data privacy guidelines.

One or more years: Click the "One or more years" button. Then select a year, or hold down the Control (Ctrl) key and select more than one year.

Specify your own years: Click this button, then enter the years of interest, one per box or as a range.

Note: To see results for a series of years (or a series of year groups), first select the years of interest here, then choose "Year(s)" as a ROW or COLUMN variable in Step 6 or 7 below.


Step 4. Choose Cause of Death (Optional)

Caution: There was a change in the classification system for causes of death in 1999. If you are selecting cause of death for multiple years that include both ICD-10 (1999 and later) and ICD-9 (1989-1998) codes, read the Trend Analysis Caution and Comparability Ratios (PDF). Combining or comparing causes for years that include both ICD-10 and ICD-9 codes can result in misleading information.

Step 5. Choose Specific Characteristics (Optional)
