Trends and risk factors for suicide mortality in India from 2001-2019: National mortality study.
Level 3 - non-randomized controlled study
Nationally representative population-based mortality study using verbal autopsy adjudication

What was done
Researchers analyzed over 20,000 suicide deaths among 829,000 total deaths recorded between 2001 and 2019 from a nationally representative random sample covering approximately 1% of Indian households. Cause of death was established through lay field interviews followed by dual central medical adjudication. Suicide death rates were calculated by applying proportional mortality to national demographic totals, and risk factors were assessed across demographic groups.
What was found
Suicide mortality rates declined by 1.5% per year from 2001 to 2019, but population growth kept the absolute annual toll steady at approximately 200,000 deaths (totaling 3.8 million deaths over the study period). Most suicides occurred in early-to-middle adulthood: 44% at ages 15–29 and 50% at ages 30–69. The fastest rate declines occurred in young women (ages 15–29), particularly after 2015. Method patterns shifted: deaths from poisoning (mainly organophosphate pesticides) decreased, while hanging increased. Geographic variation was pronounced, with suicide risk at ages 15–69 being roughly eight times higher in selected southern high-burden states compared to selected northern states. Individual risks were highest among sons- or daughters-in-law, rural residents, and men who consumed alcohol.
Why it matters
India accounts for one-quarter of global suicide deaths, yet high-quality national epidemiology has historically been limited. These findings reveal that despite declining per-capita rates, the absolute burden remains massive, shifting from pesticide ingestion to hanging and showing severe regional and household disparities that should guide targeted prevention policies.
Limits
Mortality classification depended on verbal autopsy (lay field reporting with post-hoc medical adjudication), which is vulnerable to recall bias, family concealment, and misclassification of stigmatized deaths. Detailed clinical psychiatric histories, prior non-fatal attempts, and specific socioeconomic variables beyond broad household categories were not captured in the abstract.
