Infant Mortality Rate
Infant Mortality Rate
The infant mortality rate (IMR) is used around the world as a measure of health. The IMR rate counts the number of infants born alive who die before their first birthday. This number is counted for every 1,000 live births
How is the Infant Mortality Rate Related to Community Health?
The leading causes of death for infants are birth defects, problems resulting from premature birth, infection, injury, low birth weight, and sudden infant death syndrome (SIDS). Other factors that may affect the IMR are the age of the mother, prenatal care, race, nutrition, insurance, and contact with lead and other chemicals in the environment. Some studies find a link between the IMR in a community and socioeconomic status, access to health care, general health status, and the mother’s education level.
Minnesota’s IMR has been 4.8 since 1995. This is the lowest IMR in the United States. This is largely due to strong maternal and child health programs, high insurance coverage, lower poverty levels, and overall healthier lifestyles. However, from 2003-2005, the IMR in Minnesota varied by race and ethnicity: for whites it was 4.3, for African-Americans it was 8.7, for American Indians it was 8.6, for Asians it was 3.8, and for Hispanics it was 4.3 (each is for every 1,000 live births). The Minnesota Department of Health (MDH) is actively involved in programs to reduce these health disparities.
What the Map Shows
The map shows the IMR in the Central Corridor for 2002-2006. Because the number of infant deaths in the Central Corridor is small for each individual year, infant deaths from 2002-2006 were combined in each Zip code to show the IMR. In the Central Corridor, the IMR was 7.1 compared to 6.4 for the Twin Cities, 4.8 for Minnesota, and 6.6 in the United States for every 1,000 live births. (Click on the map for a larger image.)
Death certificate information reported by physicians and hospitals to the Center for Health Statistics at MDH is used to calculate the IMR. Because the numbers of infant deaths are so small, this map does not show the race or ethnicity of the child.
