Health >> Infant Mortality >> Trends by Race/Ethnicity

From 2004 to 2010, the infant mortality rate did not change for any race/ethnicity group.

If a baby dies before his or her first birthday, that death is counted as an infant death. The number of infant deaths per 1,000 live births is known as the infant mortality rate, and is widely regarded as an indicator of the overall health of a community. 

For trend graphs, 3-year rolling averages were used to smooth out the large effects of year-to-year fluctuations.  King County’s 2010 infant mortality rate was 4.2 deaths per 1,000 live births; the average rate for 2006-2010 was 4.1 deaths per 1,000 live births.

  • NOTE:  Trend data by race/ethnicity do not go back 10 years because race/ethnicity data were categorized differently beginning in 2004: Asians and Native Hawaiians/Pacific Islanders were considered separate groups and mothers could identify as more than one race.
