An Aizawl-based NGO, New Life Charity Society (NeLICS), recorded and analysed these deaths between September 2005 and October 2014.
"The main cause of suicide in Mizoram is depression and the majority of the people who commit such acts belong to the youth category," Zawmsanga Sailo, NeLICS chairman, told reporters Wednesday.
NeLICS records show most victims were between 15 and 45 years.
Zawmsanga said: "Seventy-five percent of the suicides in the nine years were committed by males."
The oldest person who committed suicide was a 86-year-old man while the youngest was an eight-year-old boy.
Zawmsanga said the misuse of technological advancement in the form of mobile phones among the young had largely attributed to suicides.
