Democracy
The ‘‘Polity 2’’ score is a multicomponent historically informed measure of fair
political competitiveness, formalized constrains on the abuse of power, and citizens’
ability to freely exercise civil liberties that is drawn from the Polity IV database
to model national-level democracy. These scores range from −10 to +10 and
have been applied in similar cross-national analyses (see Groshek, 2010; Gurr &
Associates, 1978)
