As of the 2011 Census of India, the population of Kiphire town was approximately 16,487, though recent estimates suggest growth in the intervening decade. The town has a fairly even gender ratio, and a significant portion of the population is young.
Kiphire is predominantly inhabited by Scheduled Tribes (ST), with the Sangtam, Yimkhiung, and Sumi Nagas making up the vast majority of the residents. Christianity is the dominant religion, practiced by nearly the entire indigenous population, with Baptist denominations being the most prevalent.
English is the official language and is used in government and education. Nagamese serves as the crucial lingua franca for inter-tribe communication, while indigenous languages (Sangtam, Yimkhiung, Sumi) are spoken at home. Education levels in the town are relatively high compared to rural hinterlands, though the region faces challenges in high-level employment opportunities, leading many youths to migrate to Kohima, Dimapur, or mainland India for work.
