Health >> Infant Mortality >> Trends by Poverty

From 2001 to 2010, infant mortality declined in King County’s high-poverty neighborhoods.

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.

  • Since 2001, infant mortality has declined significantly only in high-poverty neighborhoods. 
  • Despite this decline, infants in high-poverty neighborhoods were still more likely than infants in low-poverty neighborhoods to die in the 1st year of life.
