Plavno, Oćestovo and Polača had basically the same or even larger population than Knin. With increased urbanisation and industrialization in post-WWII socialist era (1945-1991), Knin urban population rapidly increased from 2,600 to 12,300. At that point, more than a half of municipality's population lived in the town of Knin. After 1991, due to the war and population displacement, as well as transition shock and deindustrialization, population has been steadily declining. The 1857 data shows that 75,55% of the town population was Roman Catholic. According to the Austrian Census held in 1900, the town of Knin had 1,302 residents. In 1910 the town had 1,270 citizens. After 1945, with urbanization and modernization, Knin attracted much of the countryside population which was overwhelmingly Serbian Orthodox. As a consequence, ethnic/religious composition of town changed as well. Intermarriages and a desire to straddle the divide between the communities resulted at one point in a substantial part of the population declaring themselves as Yugoslavs rather than either Croats or Serbs (22% in 1981 census). Population of the town from 1830 to 2011, based on religion, language and ethnicity was as follows: Archeology The recently discovered Roman town Burnum is 18 km away from Knin in direction of Kistanje. There are the remains of the biggest amphitheater in Dalmatia built in 77 AD, during the rule of Emperor Vespasian which could host 8,000 people. The nearby villages Biskupija and Kapitul are extremely interesting archeological sites from the 10th century where many remains of medieval Croatian culture are found including churches, graves, decorations, and epigraphs. Sport The most successful sports in Knin lately have been track and field and martial arts. The latter is particularly popular with two taekwondo clubs active. Matea Jelić, Knin native (*1997) started practicing taekwando in Knin and later became 2020 Olympic champion in 67 kg. Track and field club "Sv. Ante" (St. Anthony) in Knin boasts Croatian 100m and 200m sprint as well as long jump national champion, Marko Čeko, who also won the Hanžeković memorial in 2020 in men's long jump.
