This indicator represents births to mothers who receive no prenatal care at all, or receive prenatal care beginning after the first trimester. The first trimester is calculated, based on elements obtained from the birth certificate, as the date of LMP (last menstrual period) through day 88 of the pregnancy.
The denominator for the percentage is total resident live births in respective geographic areas.

GEOGRAPHY - Data are reported by the mother's place of residence rather than the location of the hospital where the birth occurred. Because vital records data specific to American Indian reservation boundaries are unavailable, tribal data were collected based on births to American Indian mothers in counties associated with reservation boundaries. Tribal data for this measure were collected as follows:
Fort Berthold Reservation: Resident live births to American Indian mothers in McLean, Mercer, Dunn, Mountrail, and McKenzie counties.
Spirit Lake Reservation: Resident live births to American Indian mothers in Ramsey, Benson, and Eddy counties.
Standing Rock Reservation (North Dakota portion): Resident live births to American Indian mothers in Sioux County.
Turtle Mountain Reservation and Off-Reservation Trust Land (North Dakota portion): Resident live births to American Indian mothers in Rolette County.

DATE - Calendar Year (January 1 - December 31).
LIMITATIONS - Data are not reported for geographies where the number of births to mothers receiving late or no prenatal care is five or less. In these cases, "LNE" is indicated for a Low Number Event.
