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.
Unstable Rates:In order to produce a meaningful graph, some single-year, unreliable rates were smoothed using additional years of data. 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.
Diagnoses are coded using the 9th revision to the International Classification of Diseases - ICD 9 CM. Diagnostic Code Groupings used for congenital anomaly codes are as used by the Centers for Disease Control. (See Birth Defect Groups and ICD-9-CM Diagnosis Codes for the codes used to categorize birth defects.)
