Pazardzhik is a city situated along the banks of the Maritsa river, southern Bulgaria. It is the centre of Pazardzhik Province and Pazardzhik Municipality. It is located in the Upper Thracian Plain and in the Pazardzhik-Plovdiv Field, a subregion of the plains. It is west of Plovdiv, about 37 kilometres (23 mi), 112 kilometres (70 mi) southeastern of Sofia and 288 kilometres (179 mi) from Burgas. The population is 55,220, as it has been growing around from the end of the 19th century to the end of the 20th century. The city reached its highest milestone, exceeding 80,000. Due to poor economic performance in Bulgaria during the 1990s and early 2000s, emigration of Bulgarians began, which affected Pazardzhik as well.
