This study attempts to evaluate the impacts of macro-structural factors on political freedom in developing countries (DCs). Political freedom is conceptualized as civil liberty and political rights the general population of a society can enjoy in influencing public policy. The Freedom House indexes are used as measures of freedom. In explaining the individual countries' differences in political freedom, this study considers the following factors: regime types, level of development, social structure, fractionalization, the state and military influence and external economic dependence. Empirical modeling of 118 DCs with regression techniques and ordered logit methods demonstrates that besides the regime effects, economic development generates favorable influence, while a large poor population and military spending produce negative impact on freedom. In the concluding section, we discuss the theoretical implications in comparative perspective.
