Bhutan can culturally and geographically be divided into three regions, which are further divided into 20 districts or dzongkhags (districts), administered by a body called the Dzongkhag Tshogdu. In certain thromdes (urban municipalities), a further municipal administration is directly subordinate to the Dzongkhag administration. In the vast majority of constituencies, rural gewogs (village blocks) are administered by bodies called the Gewog Tshogde.
Thromdes (municipalities) elect Thrompons to lead administration, who in turn represent the Thromde in the Dzongkhag Tshogdu. Likewise, gewogs elect headmen called gups, vice-headmen called mangmis, who also sit on the Dzongkhag Thshogdu, as well as other members of the Gewog Tshogde. The basis of electoral constituencies in Bhutan is the chiwog, a subdivision of gewogs delineated by the Election Commission.
