Infant mortality is defined as the death of an infant before his or her first birthday. Infant mortality is related to the underlying health of the mother, public health practices, socioeconomic conditions, and the availability and use of appropriate health care for infants and pregnant women.47, 48
‡ Reporting standards not met; the number of deaths is too few to calculate a reliable rate.
NOTE: NH = non-Hispanic origin. Infant deaths are deaths before an infant's first birthday. Among Native Hawaiian or Other Pacific Islander infants, the number of infant deaths is generally too small to meet reliability standards and therefore are not shown. Race refers to the mother's race. The 1997 U.S. Office of Management and Budget (OMB) standards on race and ethnicity are used to classify persons into one of the following racial groups: White, Black or African American, Asian, and American Indian or Alaska Native. All categories are single race. Included in the total, but not shown separately, are people reporting two or more races. Data on race and Hispanic origin are collected and reported separately. Persons of Hispanic origin may be of any race. The OMB classifies counties as within a metropolitan or a micropolitan statistical area. The remaining counties are not classified and are considered rural in this report. Rural counties may include small urban areas, as well as completely rural areas. Nonmetropolitan counties include counties in micropolitan statistical and rural areas.
