The Kingdom of Bhutan is divided into 20 districts. Bhutan is located between the Tibet Autonomous Region of China and India on the eastern slopes of the Himalayas in South Asia. Dzongkhags are the primary subdivisions of Bhutan. They possess a number of powers and rights under the Constitution of Bhutan, such as regulating commerce, running elections, and creating local governments. The Local Government Act of 2009 established local governments in each of the 20 dzongkhags overseen by the Ministry of Home and Cultural Affairs. Each dzongkhag has its own elected government with non-legislative executive powers, called a dzongkhag tshogdu (district council). As of the 2017 census, Thimphu (Tashichho Dzong pictured) is the most populous dzongkhag, with 138,736 residents; Gasa is the least populous, with 3,952 residents. Thimphu is the most densely populated, with 67.1 people per km2, whereas Gasa is the least densely populated, with 1.3 people per km2. (Full list...)
