Kitsap County ranked seventh in the state in the number of same-sex marriages in Washington since same-sex marriages became legal on Dec. 6.

According to the Washington State Department of Health, nearly 2,500 same-sex couples were married in Washington in the 16-week period between Dec. 6, 2012 and March 31, 2013.

All told, same-sex marriages accounted for more than 20 percent of the 11,661 marriages that occurred in Washington during the four-month period.

All but four counties in Washington — Ferry, Asotin, Garfield and Wahkiakum — reported performing same-sex marriages.

King County topped the list in the number of same sex couples tying the knot. A total of 1,321 marriages, or one-third of the marriages performed in King County, were same-sex marriages.

Clark County — which sits just across the Columbia River from Portland, Ore. — was second in same-sex marriages during the first 16 weeks of same-sex marriages, with 204.

Pierce County was third (171 marriages); Thurston County was fourth (124); Snohomish County was fifth (120); and Spokane County, sixth (88).

The number of same-sex marriages in Kitsap was lower than the statewide average; 13 percent of marriages recorded in the county were same-sex (or 63 out of a total of 459 marriages).

Officials with the state Department of Health said most of the same-sex marriages in Washington state, about 63 percent, involved female couples.

The health department also said in 14 percent of same-sex marriages, both spouses were residents of another state.

By contrast, among opposite-sex couples, both spouses were from another state in only 4 percent of marriages.

The state health department noted the actual number of same-sex marriages may change, as some counties may have not yet received records for all marriages during the reporting period.
