Comparable Healthy People 2010 Objective: 
Retained from HP2010 objective
Data Collection Frequency: 
Annual
Methodology Notes: 

    To create linked data files, death certificates are linked with corresponding birth certificates for infants who die in the U.S. before their first birthday. The linked file is used for calculating infant mortality rates by mother's race and ethnicity because these variables are more accurately collected on the birth certificate than the death certificate.

    Beginning with the 2015 data year, the obstetric estimate of gestation at delivery (OE) is considered the standard measure for estimating gestational age in perinatal mortality. The OE replaces the measure based on the interval between the first day of the last normal menses (LMP) and the date of delivery — which was used for the 2005 to 2014 data.

    This transition was made because of the increasing evidence of the greater validity of the OE compared with the LMP-based measure. Accordingly, beginning with the 2015 data year, gestational age data are based on the OE.

    Descriptions of LMP and OE have been published by NCHS.

    The use of the different gestational age measures resulted in only a small difference in the total number of live births plus fetal deaths at 28 weeks of gestation to less than 7 days after birth in 2015 (3,990,452 vs 3,989,866). For 2015, the OE-based perinatal mortality rate was 6.0 fetal and infant deaths at 28 weeks of gestation to 7 days after birth per 1,000 live births and fetal deaths, compared to the LMP-based rate of 6.1

Trend Issues: 
Reporting of marital status of mother was discontinued in 2014.

Description of Changes Since the Healthy People 2020 Launch: 
In 2017, the estimates for geographic location were updated to reflect the 2013 urban/rural classification scheme.
