One way that social scientists categorize and describe political regimes is to analyze the nature of the executive branch of government, particularly the makeup of cabinets. The assumption is that the structure of the cabinet and the class background, and the educational or occupational training of ministers reflect the nature of the regime. Those at the top of the state may represent certain groups in society or be particularly responsive to the demands of the social groups from which they come. Background characteristics may also be a good indicator of the style of rule. Education, training, age, occupational career, all indicate how decision-makers think, how they organize to approach problems, how they issue orders and use subordinates. The institutional background of ministers may reflect the importance of various institutions in society, for the connection of institutions through individuals at the top of the state may be a good indication of which specialized constituencies must be consulted, which command power and which control political, economic, and social resources.
