Phuntsholing had more than 10,000 people. According to the United Nations, the urban population growth rate for 2000–2005 was 6.0%.
Some 93% of the population was rural in 2001. The laboring population is not gathered into towns but lives in the countryside in the vicinity of fortresses called dzongs . A dzong , the official center of a region or district, often houses substantial numbers of Buddhist monks. Many place names incorporate the word dzong, which means "castle-monastery."
