Introduction/Methodology
NZ Police Stats provide Demographic breakdown of offenders over time. Using the Census 2023 data, we can calculate the “per-capita” rate of Offending for each group, by dividing the total reported crimes by the number of people in each group. We then multiply that by 100,000 – showing the rate of offending per 100,000 people. This helps give a better picture than simple raw totals when group sizes differ.
The crime information is sourced from the policedata section of the NZ Police site, it is a public Tableau database that is updated monthly.
For this report I used the “Unique Victims (demographics)” and for Homicide and Dangerous Acts, the Unique Offenders Tableaux, using the Detail tab, to determine the volumes of crimes committed by people by demographic. I then filtered by “Known to Victim – Family Member”.
For per-capita values, the “Undefined” and any unknown categories are Excluded from the total. This is any reported crime where the Ethnicity of the Offender is undetermined. Any entries with an Outcome of “Not Proceeded With” have been excluded.
** While it would be very interesting to be able to combine these reports to show which ethnic groups were victimising each ethnic groups, that is not possible with the Public Police Tableau data, though this IS family member crime..
