The populations of Bangladesh are almost evenly distributed throughout its 64 districts except for the three Hill Tracts districts which are rather sparsely inhabited. Regionally, the eastern districts have a slightly higher density than the western ones. On average, a district has a population of about 1.8 million, a thana 230,000, a union 25,000 and a village 2,000. There are 490 thanas, 4,451 unions and 59,990 villages. The number of households is about 20 million. On average, a household consists of 5.6 persons. The tribal people, who lead a simple life, are generally self-reliant, producing their own food and drinks and weaving their own clothes.
