First preference vote and seat totals by local electoral area. As this is a STV election, seat totals are determined by popular vote and preferences in each local electoral area.
Following a recommendation of the 2018 LEA boundary review committee, the only change to the areas used at the 2014 election was to move the electoral division of Claddagh from the West LEA to the Central LEA in line with population changes revealed by the 2016 census.[1][2]
Fianna Fáil became the largest party on the City Council gaining 2 seats in the process. Fine Gael lost 1 seat despite slightly increasing their vote. The Green Party emerged as the big winners winning 2 seats; 1 in each of Galway City Central and Galway City West and a nearly 5 fivefold increase in voteshare. Following two recounts the Social Democrats held onto a seat in Galway City East at the expense of Sinn Féin, and lost a seat in City Central to the Greens. Sinn Féin lost all their seats as their vote collapsed almost in half. To a significant extent the rise in support for both the Social Democrats and the Greens contributed to the loss for Sinn Féin.
