Birth Outcomes Data

The birth dashboards present birth counts and rates, fertility patterns and maternal and infant health characteristics in Washington State. Birth data are compiled from information on pregnancies and deliveries from birth certificates.

Why is birth outcome data important?

Birth outcome measures show the status of reproductive health across populations. It shows data on fertility, prematurity, low birth weight, and sex ratio. Birth outcomes may be different across geographic areas due to access, level of care, social and environmental exposures and behavioral characteristics.
