Key findings
• About 0.2 million deaths at ages 15 years and older in 2010
were due to suicide.
• 54% of female and 40% of male suicides occurred at ages
15-29 years.
• A 15 year old south Indian male had a 3.5% risk of dying
from suicide before reaching 80 years, in the absence of the
other causes.
• About half of suicide deaths were due to poisoning.
• Age standardised suicide death rates at ages 15 years and
older were two fold higher in rural areas than urban areas.
• Suicide death rates vary markedly between states.

What’s new about this research?
• Previous suicide estimates have used the
National Crime Records Bureau numbers,
which are based on police reports
• These data could under-report suicide,
as attempted suicide is a crime in India
• The Million Death Study provides direct
suicide estimates by age, gender, area and
method of suicide from a nationally
representative sample.

How was the study done?
800 Registrar General of India field workers interviewed 122
thousand families of people who had died in 2001-2003
Written reports each coded independently by at least two
physicians to attribute a probable cause of death (i.e., suicide)
Calculated proportion of all suicide deaths by age, gender,
and area within the study

How was the study done?
Combined with national 2010 UN totals of deaths, and
2007-2009 state-specific SRS death rates
Produced national and state estimates of rates
and number of suicide deaths for 2010
