IDI is a composite indicator that shows the level of democratic development in Indonesia. The level of achievement is measured based on the implementation and development of three aspects of democracy, namely Civil Liberty (Civil Liberty), Political Rights (Political Rights), and Democratic Institutions (Institution of Democracy).
IDI calculation methodology uses 4 data sources, namely: (1) review of local newspapers, (2) review of documents (Perda, Pergub, etc.), (3) Focus Group Discussion (FGD), and (4) in-depth interviews.

The achievement of North Sumatra's democratic performance is still in the "medium" category. The classification of the level of democracy is grouped into three categories, namely "good" (index> 80), "medium" (index 60 - 80), and "bad" (index <60).
