A decade after separation became a district, in fact Samosir regency has not experienced a shift of economic structure and growth of the economic structure of the district experienced a positive growth. The largest sector contribution to GDP is agricultural sector by 67,35 percent followed by 18,62 percent service sector and trade, hotel and restaurant of 9,02 percent.

Based on the level of rice security threat, 9 villages belong to categorized of medium and 4 villages belong to high category, while based on level of potential rice fields conversion 8 villages belong to categorize of low, 2 villages belong to medium category and 3 villages belong to high category. The balance of rice in the sub-district Ciampea is deficit, because almost entire village belong to deficit status and only one village has surplus status.
