Why should I be concerned about birth outcomes?

Birth outcome measures show the status of reproductive health across populations. We can use measures such as the rate of low birth weight or the rate of infant mortality to examine disparities in maternal/child health, evaluate intervention strategies, or project long term impacts of health care access policies.

  • Between 2014-2016, there were 268,050 live births and 1,223 infant deaths, a rate of 4.6 deaths per 1,000 live births.
    • In 2017, 1703 had low birth weight (2,500 grams or less), representing about 2% of full-term singleton births.
    • In 2017, 6,945 were preterm, born before 37 weeks of gestation, representing about 8% of singleton births.
