Idaho State Counties
Boundary: Late or no prenatal care

Late prenatal care is the care received starting in the third trimester of pregnancy. This indicator measures live births to mothers receiving no prenatal care in the first and second trimesters. The indicator is calculated by dividing the number of women who receive late or no prenatal care by the number of live births. We multiply the result by 100. In counties with relatively few people, a small number of women who receive late or no prenatal care may have a significant effect on percents from year to year.

In Boundary . . .

  • The percent was 9.1 in 2018, compared to 4.6 percent in Idaho

  • 14 women who gave birth in 2018 received late or no prenatal care, compared to 4 in 1998

Note: The percent is calculated by dividing the number of pregnant females who receive third trimester or no prenatal care by the number of live births. It is presented on a "per 100" basis. NA = Not Reported or Not Available. For Idaho data, the trimester care began is based on the date of the first prenatal care visit reported in the mother's medical file. Prior to 2004, the trimester care began was based on the month of care reported by the mother. Please also note that some Idaho counties have a high proportion of records with unknown data for date of first visit. Data for 2004 are not comparable with prior year's data or national data which are based on month care began. In 2004, some states (Idaho, Kentucky, New York, Pennsylvania, South Carolina, Tennessee and Washington) began reporting prenatal care data with a new system. Data for these states cannot be compared to that of other states. Please see the Technical Notes in this document for more information: (
