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.
