Notes:

Mothers' Age: Counts of birth defects for mothers ages 15-19 years old include mothers who were less than 15; Prevalence rates are for mothers less than 19 per 10,000 mothers ages 15-19.

Rates Are Per 10,000 Michigan Born Resident Live Births.  Rates include all children reported with a birth defect who were born in Michigan and whose mother was a resident at the time of birth. This enables the calculation of birth defects prevalence rates. Birth defect statistics sometimes reflect trends related to data reporting or new testing. See Data Quality Considerations for further details.
Symbols: *: Figure does not meet standards of reliability or precision. •  -: A dash represents quantity zero. •  0.0: Quanity more than zero but less than 0.05.
Conditions are reportable if identified within the first two years of a child's life. The prevalence frequencies used to calculate the rates in this table represent cases diagnosed within the first year of life.
Prior to October 2015, diagnoses were coded using the 9th revision to the International Classification of Diseases - ICD–9–CM.  (See Birth Defect Groups and ICD–9–CM Diagnosis Codes for the codes used to categorize birth defects.) After October 2015, the Birth Defect registry coded diagnoses using ICD–10–CM. (See Birth Defect Groups and ICD–10–CM Diagnosis Codes for the codes used to categorize birth defects.) Diagnostic Code Groupings used in analysis of birth defects are defined by the Centers for Disease Control.
