Madison: Infant mortality
An infant is a child under one year of age. The infant mortality rate is calculated by dividing the number of infant deaths by the number of live births. We multiply the result by 1,000. In counties with relatively few people, a small number of infant deaths may have a significant effect on rates from year to year.
