About this chart
- This chart shows the age distribution of a selected cohort (using the additional filters of gender and/or employment type) by sector and designation.
- The green boxed area of the whisker plot graph covers the 25th to 75th percentile age ranges.
- To further highlight the age range within a selected cohort the upper and lower whiskers represent the 90th and 10th percentiles respectively.
- The average age is displayed within the green boxed area using a diamond shaped icon
- The median age is displayed as a horizontal line halfway inside the green boxed area.
- We exclude designations with estimated counts – 'relevant' and 'other'.
- Scale may not begin at zero because charts auto-fit to the data.
- Show exact numbers by holding the mouse over the chart.
- Reduce the number of years displayed by selecting the "5y" tab on the upper lefthand side of the chart to just see a 5 year horizon.
- View full screen or download in different formats using the 'hamburger' menu top right.
Note
Past year numbers can change as:
- the IDI extracts are on an "as at" point in time basis, so data refreshes will re-read in any backdated data updates submitted by data providers; and
- every data refresh involves re-extracting all the past years which are then subjected to Stats NZ's random rounding rules.
