There probably were only about 2,000 monks in the state supported monasteries in 1972 when his reign started. By 2006, the number of monks subsisting on state allowances had increased to little over 6,000. In parallel to the increase in the number of monks and nuns, the monastic infrastructure that included tutors, lamas, temples, (meditation centres), and shedras (Buddhist colleges), increased in Wangchuck's reign. Many new official dratshangs in district headquarters, which hitherto did not have any monastic body, were opened such as Tsirang, Gaylegphug, Tashi Yangtse, Samtse, Pema Gatshel, Chukha, Bumthang and Zhemgang. Numerous affiliate monasteries to each dzongkhag rabdey were also opened throughout the country.
