The 'Decision responsiveness and the legitimacy of public agencies' data set is focused on measuring how public agencies respond to citizen inputs and how this responsiveness affects their perceived legitimacy. It typically includes data on agency decision-making processes, responsiveness metrics such as reaction times or changes in policy following public feedback, and survey data on public trust or legitimacy perceptions. The data set is used in political science and public administration research to analyze the relationship between government responsiveness and legitimacy, often within specific countries or regions. It can include quantitative indicators from administrative records and qualitative assessments from public opinion surveys. The data set helps scholars and policymakers understand how responsive governance influences citizens' trust and the overall effectiveness of public institutions.
