The Department of Health collects information on pregnancy and delivery in Washington State from birth certificates. Information is used to calculate birth rates, fertility patterns, and maternal and infant health characteristics. These can be examined by a variety of information including maternal and paternal demographics, delivery method, length of gestation, birth weight, and plurality.
The Center for Health Statistics has significant delays for custom data files and research requests. Standard data files are currently available to order with a valid DSA.
If you have questions, you can email CHS.DataRequests@doh.wa.gov. Normal turnaround times are delayed.
View the Data
The Department of Health provides information through interactive dashboards. These dashboards allow users to:

2021 data updates for the birth dashboards have been delayed because population data to calculate rates have been unavailable. 2021 WA resident counts by county, sex, age, and race. (xlsx)

A DSA documents the conditions under which the Department of Health shares limited datasets containing potentially identifiable information with outside entities. By signing the DSA, the recipient(s) of the data agrees to not link information with any other information that could identify an individual or use the information to contact any individuals. Data may not be disclosed unless agreed upon in the DSA.
