[1] Sergithang Gewog is located in the northwest of Tsirang District, east of the River Puna Tsang Chu, north of its tributary Burichu, west of Pungtencchu Gewog and south of Wangdue Phodrang District.

According to the official results of the 2017 census, 1.379 inhabitants (731 males and 648 females) live in the Serithang Gewog in 300 households.

Transportation is still a big problem even for these three central chiwogs, because the distance from Sergithang to Damphu is 48 km, 37 km of it on dirt, winding roads which remain closed for almost a quarter of a year annually.

According to a report of the Bhutan Chamber of Commerce and Industry of 2014 there is an "immediate plan" to build a 10 km long road to which would connect the Gewog directly to the Tsirang-Wangdue National Highway at the Buri Chu confluence.

Inhabitants need three and six hours, respectively to reach the road in Sergithang and Tashithang.
