80% of likely Washington voters want to set a minimum age to marry

Eight out of ten like­ly 2024 Wash­ing­ton vot­ers are sup­port­ive of adopt­ing leg­is­la­tion that would put an end to child mar­riages in the Ever­green State, a poll recent­ly con­duct­ed for the North­west Pro­gres­sive Insti­tute has found.

80% of 700 like­ly 2024 Wash­ing­ton State vot­ers sur­veyed by Pub­lic Pol­i­cy Polling for NPI in Novem­ber of 2023 expressed sup­port for enact­ing leg­is­la­tion that would require both par­ties to be at least eigh­teen years old to legal­ly marry.

A mere 14% were opposed, while 6% said they were not sure.

It’s very rare that we find the vot­ing pub­lic in Wash­ing­ton this unit­ed behind pend­ing state-lev­el leg­is­la­tion, but it goes to show that even in polar­ized times, there are areas of bipar­ti­san, cross-ide­o­log­i­cal agreement.

End­ing child mar­riage is one of the North­west Pro­gres­sive Insti­tute’s 2024 leg­isla­tive pri­or­i­ties, and it has a first-rate cham­pi­on in State Rep­re­sen­ta­tive Mon­i­ca Stonier, who intro­duced House Bill 1455 last session.

Fit­ting­ly, HB 1455 received no oppo­si­tion what­so­ev­er when it appeared on the House floor last year, reflect­ing the deep and strong sup­port for end­ing child mar­riage that we can now see in our research polling.

Regret­tably, HB 1455 stalled out in the Sen­ate due to a mas­sive log­jam of bills that sen­a­tors weren’t able to ful­ly clear due to time constraints.

(Unlike Con­gress, Wash­ing­ton’s bicam­er­al Leg­is­la­ture is only in active reg­u­lar ses­sion for 105 days in odd years and 60 days in even years.)

But since bills from odd year ses­sions car­ry over to even year ses­sions, Rep­re­sen­ta­tive Stonier does­n’t have to start over with a new bill. The House can sim­ply send HB 1455 back over to the Sen­ate a sec­ond time, where Law & Jus­tice Chair Man­ka Dhin­gra — a North­west Pro­gres­sive Foun­da­tion board­mem­ber — is ready to hear it and report it out with a “do pass” recommendation.

HB 1455 could be on Gov­er­nor Inslee’s desk in a mat­ter of weeks if the Sen­ate fol­lows the House­’s lead this time and approves the bill unanimously.

Our research shows Wash­ing­to­ni­ans are very enthu­si­as­tic about HB 1455.

Here’s the exact ques­tion we asked and the respons­es we received:

QUESTION: Wash­ing­ton State cur­rent­ly does not pro­hib­it mar­riages in which one or both par­ties are under the age of eigh­teen. Do you strong­ly sup­port, some­what sup­port, some­what oppose, or strong­ly oppose pass­ing a law to end child mar­riage by requir­ing that both par­ties be at least eigh­teen years old to legal­ly marry?


  • Sup­port: 80% 
    • Strong­ly sup­port: 64%
    • Some­what sup­port: 16%
  • Oppose: 14%
    • Some­what oppose: 8%
    • Strong­ly oppose: 6%
  • Not sure: 6%

Our sur­vey of 700 like­ly 2024 Wash­ing­ton State vot­ers was in the field from Tues­day, Novem­ber 14th through Wednes­day, Novem­ber 15th, 2023.

The poll uti­lizes a blend­ed method­ol­o­gy, with auto­mat­ed phone calls to land­lines (42%) and online answers from respon­dents recruit­ed by text (58%).

It was con­duct­ed by Pub­lic Pol­i­cy Polling (PPP) for the North­west Pro­gres­sive Insti­tute, and has a mar­gin of error of +/- 3.7% at the 95% con­fi­dence interval.

Fol­low this link for addi­tion­al method­ol­o­gy details, includ­ing demo­graph­ic data.

NPI and PPP have worked togeth­er for a decade and have a track record of excel­lence, as detailed in this 2022 elec­toral polling recap and this 2020 one.

Child mar­riage has been declared by the Unit­ed States Depart­ment of State to be a human rights vio­la­tion. Yet, in much of the coun­try, it’s legal — includ­ing in all of the states in the Pacif­ic North­west. That needs to change.

So far, ten states have banned child mar­riage. Those are:

  • Delaware (2018)
  • New Jer­sey (2018)
  • Penn­syl­va­nia (2020)
  • Min­neso­ta (2020)
  • Rhode Island (2021)
  • New York (2021)
  • Mass­a­chu­setts (2022)
  • Ver­mont (2023)
  • Con­necti­cut (2023)
  • Michi­gan (2023)

All of those states are in the Great Lakes, New Eng­land, or mid-Atlantic regions. Wash­ing­ton could become the first state in the Amer­i­can West to ban child mar­riage if House Bill 1455 is successful.

Wash­ing­ton has a his­to­ry of human rights lead­er­ship, includ­ing the suc­cess­ful repeal of the death penal­ty. Let’s con­tin­ue that lead­er­ship in 2024 by mak­ing sure the Ever­green State becomes the next state to end child marriage.
