and this news article about a women who received 11 months home detention for pushing her husband down the stairs, killing him got me into a discussion about whether it is men or women are treated more leniently when it comes to domestic violence.

Using these tables from NZStats, here’s what I’ve got:

(The murder statistics aren’t that interesting, because for both men and women, almost all of them result in imprisonment, and the length of sentences isn’t available).

Some thoughts:

  • Men obviously commit more manslaughter than women
  • The sample size for women is a lot smaller, meaning that any noise is going to have a much bigger effect
  • But that said – eyeballing it, about 1/3 of women convicted of manslaughter get a non-custodial sentence, while almost all men get a custodial sentence
  • It’s possible that men commit more serious manslaughter offenses
  • It’s possible that women plead guilty earlier, or express more remorse

The data for assualts is more pronounced. There are a lot of of them, and so we can more safely extract trends:

Men, Assault
Sentence Total sentences   Imprisonment sentences   Community sentences   Monetary   Other   No sentence recorded
2007/08 7980 1401 4063 1336 781 399

2015/16 6497 1497 3914 511 487 88
2016/17 6545 1498 4063 439 441 104
Women, Assault
Sentence Total sentences   Imprisonment sentences   Community sentences   Monetary   Other   No sentence recorded
2007/08 1349 72 697 245 246 89
2008/09 1588 82 833 269 305 99
2009/10 1675 96 937 225 312 105
2010/11 1704 110 996 192 319 87
2011/12 1605 104 948 191 277 85
2012/13 1374 90 860 148 207 69
2013/14 1226 87 799 105 196 39
2014/15 1224 95 803 103 186 37
2015/16 1263 100 845 85 194 39
2016/17 1182 84 801 90 172 35

Around 20% of men who are convicted of assault get a custodial sentence.

Around 7% of women who are convicted of assault get a custodial sentence.

    • It’s likely that the assaults men commit are more serious
    • Men are probably more likely to have commited prior offences

In any case – some pretty good refuting evidence would be required to suggest that women are treated more harshly when it relates to violence offenses.
