National Crime Records Bureau – Suicide Stats – 2012 (Part 2)
June 25, 2013 7 Comments
This is the part 2 of the National Crime Records Bureau’s (NCRB’s) suicide statistics. The part 1 of the statistics are here. In this part we will try to explore if any causal effects are there to a rise in the male suicides.
In discussion with a few male rights activists, false criminal cases and gender biased laws were cited as a probable reason for despair in men. In this article we will analyze if the Protection of Women from Domestic Violence Act, 2005 commonly referred to as the Domestic Violence Act (DV Act) has a causal relationship in increasing in suicides among men.
The DV Act was brought in force by the government on October 26, 2006 and it provides for protection of women from domestic violence in a marital home. This act also provides certain rights to women such as right to matrimonial home, right to receive protection orders and right to maintenance to name a few.
Method of Analysis
Regression Analysis is used as a method to analyze the data. Past suicide data for married men for 2001 to 2012 has been used as a the dependent variable, as the DV Act is specifically for protection of married women.
The predictor variable was considered to be ‘mid year population of India’ and a qualitative variable – ‘DV Act’.
Model:
Therefore the model is defined as:
Y= αX_{1} + βX_{2} + ε
Where:
Y = Suicides by married men
X_{1} = mid year population
X_{2} = Qualitative variable of enacting the DV Act
α = change in Y due to X_{1}
β = change in Y due to X_{2}
ε = error term
Hypothesis:
We define our hypothesis as:
H_{0} (Null Hypothesis) = There is no relationship with enacting the DV Act and suicides by married men
H_{1} (Alternate Hypothesis) = A positive relationship may exist between enacting of DV Act and suicides by married men
Data:
For evaluating the hypothesis, married male suicide data and midyear population from the year 2001 to 2012 was mined from NCRB’s data tool[i]. As the DV act was brought in force in October 2006, the variable X_{2} is taken as ‘0’ for periods 2001 – 2006 and as ‘1’ for 2007 2012.
The data in a graphical form is given below:
Results:
The results of the regression are given below –
Coefficients 
t Stat 
Pvalue 

Mid Year Population Estimate (X_{1}) 
4.64 
75.44 
0.00 
Enacting DV Act (X_{2})  4,817.11  4.91  0.00 
Model R^{2}: 0.9993
Analysis:
As seen above the ‘t stat‘ for enacting DV Act is 4.91, which is over the minimum 4.14 (for 10 degrees of freedom at 99% confidence) required to accept this variable as a valid predictor of married men suicides. Further, the pvalue in this case is 0.00, which in simple term implies the probability of null hypothesis being true (Null hypothesis being that there is no relationship with enacting the DV Act and suicides by married men).
Further the R^{2} (coefficient of determination) of the model is 0.9993 which signifies that the model has a predictive ability of 99.93% (ie. The model can predict correctly 99.93% times). In statistical terms R^{2} is often interpreted as the proportion of response variation (Y) “explained” by the regressors (X_{1} and X_{2}) in the model.
Therefore, we reject the null hypothesis (H_{0}) and accept the alternate hypothesis which states “A positive relationship may exist between enacting of DV Act and suicides by married men”.
Hence, based on the data above it may be said that enacting of the DV Act may have led to increase in suicides by married men.
Suicides by Married Women:
The same model was applied to suicides for married women as a counter check. The null hypothesis in this case was not rejected (ie. accepted) as the ‘t stat’ for enacting DV Act for women was 1.71, which was below the minimum t stat required to reject the null hypothesis. Hence, the DV Act cannot be said to be a predictor for married women suicides (ie. It only increases suicides in married men).
Conclusion:
Gender biased laws such as DV Act may have a bearing in increasing suicides in married men, as seen in the statistical analysis above.
Please Note: Do feel free to comment on this post if you require understanding on any data point or if you believe that there has been an error/omission in the analysis (constructive criticism is appreciated) . I would be happy to update/include your comments in the article as appropriate or respond to your comments.

Very good article, thanks for sharing….
Picture is very clear because of DV Act, 498a & defamation Indians mens are loosing their lives & actual DV is happening on Indian mens….
Can you do a similar analysis with 498a..
So should it be assumed based on the above analysis that DV act is driving the increase of male suicides. So should it be called as state sponsored terrorism or a similar term? Not sure.
But it is too bad that people are driven to commit suicides either male or female due to n number of reasons.
Further indepth analysis is required to come to any conclusion, but whatever be the reason increase in the number of suicides is a matter of concern.
Excellent article
thanks
