Tiya is best known for its adjacent archeological site, which is distinguished by 36 standing stones or stelae, "32 of which are engraved with enigmatic symbols, notably swords," marking a large, prehistoric burial complex. A German ethnographic expedition had visited the site in April 1935, and had found at one hour's journey to the south of the caravan camp the stone monoliths with sword symbol, which had been seen earlier by Neuville and Père Azaïs. The archeological site was designated a World Heritage Site in 1980.
Based on figures from the Central Statistical Agency in 2005, Tiya has an estimated total population of 3,363 of whom 1,615 are men and 1,748 are women. The 1994 national census reported this town had a total population of 1,856 of whom 894 were males and 962 were females. Tiya is one of three towns in Soddoworeda.
