ADDITIONAL INFORMATION Resident data. Data in these tables include Wisconsin resident births and infant deaths, regardless of the state of occurrence.

Sources. Live birth data are from birth certificate statistical files. Infant death data are from a file of the year’s resident infant deaths (death certificate data) with birth certificate information matched. Race/Ethnicity. Live births and infant deaths are classified by race or Hispanic ethnicity of mother, which are birth certificate items. The race/ethnicity categories are mutually exclusive; thus Hispanics are not included in any other race/ethnic group. Part of the increase in the number of Hispanic births from 1986 to 1990 was due to a birth certificate reporting format change implemented in 1989. Delivery type. Information on vaginal birth after cesarean was first collected in 1989. Birth rates for age groups. The < 20 birth rate is based on the 15-19 population. The 40+ birth rate is based on the 40-44 population. Infant mortality. The infant mortality rate is the number of infant deaths per thousand live births. An infant death is a death occurring to a live-born individual less than one year of age. Late or no prenatal care. This is defined as prenatal care started in the third trimester of pregnancy, or no prenatal care.
