Changed Since the Healthy People 2020 Launch: 
No
Measure: 
per 100,000 live births
Baseline (Year): 
12.7 (2007)
Target: 
11.4
Target-Setting Method: 
10 percent improvement

Denominator: 

Number of live births

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

    The maternal mortality rate indicates the likelihood of a pregnant woman dying of maternal causes. It is calculated by dividing the number of maternal deaths in a calendar year by the number of live births registered for the same period and is presented as a rate per 100,000 live births. The number of live births used in the denominator is an approximation of the population of pregnant women who are at risk of a maternal death. “Maternal deaths” are defined by the World Health Organization as "the death of a woman while pregnant or within 42 days of termination of pregnancy, irrespective of the duration and the site of the pregnancy, from any cause related to or aggravated by the pregnancy or its management, but not from accidental or incidental causes." Included in these deaths are ICD–10 codes A34, O00-O95, and O98-O99.

Caveats and Limitations: 
These rates are based on data from the 50 states and D.C. The 2003 revision of the U.S. Standard Certificate of Death includes an item on pregnancy status at the time of death and in the 42 days and year preceding death. As of 2007, 23 states and DC had adopted the 2003 revision. An additional 10 states had a separate question related to the pregnancy status of female decedents around the time of death, while 2 states had a prompt encouraging certifiers to report recent pregnancies on the death certificate; 15 states had no pregnancy-related question or prompt.
Changes Between HP2010 and HP2020: 
This objective differs from Healthy People 2010 objective 16-4 in that for Healthy People 2020, states have been encouraged to adopt the 2003 revision of the U.S. Standard Certificate of Death, which includes an item on the pregnancy status of female decedents.
