The dataset identifies the economic ideologies and political parties of heads of government in 178 countries and of political leaders (as coded by Archigos) in 178 countries from 1945 or independence to 2020. The dataset distinguishes between chief executives with leftist, centrist, rightist, and no discernible economic ideology.
