Bhutan has a unique two-round electoral system. In the first round, voters cast a ballot among all parties qualified for the election. The two parties that receive the most votes across the entire country advance. In the second round, the candidates of each of the top two parties compete in 47 single-member constituencies. In the second round, the candidate in each constituency with the most votes is elected.
If only two parties qualify for the election, as in 2008, then there is only a single round. Candidates from each party compete in the 47 constituencies and the candidate in each constituency with the most votes is elected.
The following table provides a list of constituencies from the 2008, 2013 and 2018 elections. In 2013, the Electoral Commission issued an order altering the names, but not the boundaries, of constituencies. The original names are listed in the “Old Name” columns, while the new names are listed in the “New Name” columns.
The Electoral Commission conducted its first review of National Assembly constituency boundaries in 2017 but decided to leave all boundaries unchanged.
Below are maps of constituencies by dzongkhag, the first-level regional unit below the national level. Each dzongkhag has at least two National Assembly constituencies.
