A Spatial Analysis of South Korean Presidential Elections: 2007-2022

The aim of this research is to conduct spatial analyses of the four South Korean presidential elections. Electoral support for the major parties showed clustered patterns throughout the period. In particular, support for the candidates from the right-wing party was greater in the southeast part of the country, while the southwest showed little support. Besides its spatial pattern, only one demographic factor, the elderly population, seemed to affect the election results. Finally, in the regression analysis, the spatial error model seemed to be more suitable than the OLS model.
