1 2012 Minnesota Infant Mortality Data Book This data book provides trends in infant mortality in Minnesota. The source of these data is the linked birth and death records of infants who died before their first birthday and were residents of Minnesota when they were born and when they died. The birth record is linked to the death record to gather as much information possible on the experience of the mother and infant during pregnancy and at birth. These data are presented by the year of the infant s birth not year they died. January 2014 Minnesota Center for Health Statistics Minnesota Department of Health healthstats@state.mn.us
