Birth Data

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.

Important Note:vital records law and rules are in effect that changed the requirements for requesting vital records data.

For increased security of personal and sensitive information, a data sharing agreement (DSA) is required for all vital records data, including death data. There are fees for data files, analysis, and data requests. Each application will be reviewed and vetted for compliance to laws and regulations. Sample Data Sharing Agreement.

Government agencies and Tribal governments may receive birth and fetal death record data with direct identifiers for non-research public health work by signing a DSA.
