Marriage and Divorce Data

The Department of Health gathers information about each marriage and divorce that occurs in Washington State. The filing of marriage and divorce certificates at the state level began in 1968. 

Why is marriage and divorce data important?

Marriage and divorce data provide important information about the state of American unions.  They help federal agencies understand marriage and divorce trends and forecast future needs of programs that have spousal benefits.  They also measure the effects of policies and programs that focus on the well-being of families, including tax policies and financial assistance programs. 

25% decrease in number of WA marriages from 2013 to 2020
Washington divorces have decreased steadily from 2000 to 2020
2020 saw the fewest number of marriages and divorces in Washington in two decades

What’s Here

The data in this dashboard show marriage and divorce occurrence counts and rates at the state and county level for the years 2000 through 2020. The numbers in this dashboard only reflect the number of marriages and divorces that occurred in Washington; they do not include marriages or divorces of Washington residents that occurred elsewhere.

Unions and dissolutions where the county was recorded as “Tribal Authority” are included in state totals, but not in county totals.

In 2014, 3,297 domestic partnerships were converted to marriages.  These are also included in Statewide data, but not in county totals.
