The Department of Health gathers information about each marriage that occurs in Washington State. The filing of marriage certificates at the state level began in 1968. The department does not have information about marriages or other legal unions that occurred outside of Washington State, even if the participants are residents of Washington State.
These are record level data files. Working with these data files requires spreadsheet, database management, or statistical software that are not provided. Marriage data files are available from 1968 to 2017 and contain spouse information (sex, date of birth, city and county of residence), type of ceremony, date of ceremony, county of license and ceremony, etc. Files do not contain names.
