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.

How to purchase files
These are record level data files. Working with these data files requires use of spreadsheet, database management, or statistical software that are not provided. A Data Sharing Agreement (DSA) is required to access all vital records data. Sample Data Sharing Agreement
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.
