This data shows the total number of self-harm hospitalisations among young people aged 10-24 (captured in NMDS) divided by the number of youth in the NZ resident population (Stats NZ). The title page provides further information on the measure.

Whilst the measure is meant for the youth population (<25), this report covers other age groups as well for comparison. Users have the ability to select the cohort of interest based on the drill down buttons in each tab as well as the standard population on the title page.

Note: Users should be careful when using some of the data due to quality issues. Please note the following three DHBs (of service) have unusually low discharges in the the first quarter of 2019.

• Canterbury
• Hutt Valley
• Wairarapa

With each new report, the measures for all the periods of data that are presented are recalculated, not just the latest period. In other words the latest period results are not appended to previous results. As a result differences may exist for earlier times periods if compared to previous reports. These differences could be due to late returns and/or coding changes. Users will be explicitly informed of any change in the methodology for each of the measures.
