Note:  Rates are per 1,000 live births.  The true rate lies between lower and upper bounds of the interval with 95% statistical confidence.  Records with selected characteristics unknown are included in total only. Level of prenatal care is according to the Kessner Index which is a classification of prenatal care based on the month of pregnancy in which prenatal care began, the number of prenatal visits and the length of pregnancy (i.e. for shorter pregnancies, fewer prenatal visits constitute adequate care.)
