WISH Query: Low Birthweight Module

(Data Updated September 2021)

This module creates statistics on births to Wisconsin residents, focusing on low birthweight and premature births. It provides data on the number and geographic location of births and selected characteristics of the mother, the infant, and their health care.

This revision adds 2020 birth data to the module.

To define your query, you may focus on certain counties, regions or local health departments for the most recent year or a range of years since 1990. You may also select specific maternal characteristics, such as mother's age, education, marital status, or race/ethnicity. You may select characteristics of the infant, such as gestational age or birthweight. You may also request data about prenatal care or the delivery method.

Finally, choose row and column variables for your table from a list that includes geographic areas, years, maternal or infant characteristics, and health care. See Measures Used In Birth Modules for definitions and notes on measurement.

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


Step 2. Choose One or More Geographic Areas
