Each data element for the Birth data presented above is broken down by race/ethnicity, age and community within Minneapolis. Infant Mortality data is broken down by race/ethnicity and Community within Minneapolis.

The statistical validity of data may be questionable when the number of births and infant deaths are small. In order to minimize this problem when data was analyzed by community, a three year interval is used. While analyzing data for Infant Mortality rates by race/ethnicity, a three year interval is used as the number of infant deaths are small for certain race/ethnic groups.

Data Sources

The data used in these reports comes from the Minnesota Department of Health.


The GINDEX is a prenatal care index developed by Dr. Greg Alexander of the University of Minnesota. Adequacy of prenatal care is determined by combining measures of the month or trimester prenatal care began, the number of prenatal visits and the gestational age of the fetus at the time of birth. The GINDEX includes gestational age of over 36 weeks and the number of prenatal visits exceeding nine to impute adequacy of prenatal care. An adequate or better categorization means prenatal care started in the first trimester and the woman had an adequate number of prenatal visits; intermediate means prenatal care started in the first or second trimester and the woman had an intermediate range of visits; and inadequate or none means either that prenatal care was nonexistent or started in the third trimester or that the woman had an inadequate number of visits, regardless of when prenatal care began.

Low Birth Weight
An infant weighing less than 2,500 grams (5.5 pounds) is classified as low birth weight.

The period of development of the fetus, expressed in completed weeks, calculated from the first day of the last known menstrual period.

Preterm Birth
An infant born before 37 weeks of gestation is considered preterm.

One third of the total gestational period necessary for a full-term pregnancy. Thirteen weeks are allotted each trimester. The count of weeks begins with the first day of the last known menstrual period.

Infant Death
A death of a live-born infant under one year of age.

Infant Mortality Rate
The number of children dying under a year of age divided by the number of live births that year. The infant mortality rate is also called the infant death rate and is calculated per 1,000 live births.
