In early 2007 it was proposed to merge Nurmo with the city of Seinäjoki and the neighbouring municipality of Ylistaro. Consultative referendums were held in all three municipalities. Seinäjoki voted heavily in favour; Ylistaro a bare majority in favour, and Nurmo 3:1 against. However, on 21 May 2007 Nurmo Council agreed to the merger by 18 votes to 17, and the municipality ceased to be an independent entity in 2009.
