Retention of new workers within trade industries by apprenticeship

Download data

Methodology

We take all new workers into trade industries and determine how many months they have worked within that industry over the next 5 years. From this, we determine the number of workers that retain working in the industry at each month. We apply additional breakdowns by their age group and whether they start an apprenticeship within the first year of starting work.

Note that the data has been suppressed by StatsNZ randomly rounding counts to base three, explaining why the lines are bumpy and sometimes jump up when they should not increase. To counteract this, the lines have been smoothed by a moving average with a window of 5 months.

We have included a variable slider called 'Month threshold' this allows you to limit the starting point of the retention curve to only employees who have been employed at least that many months. For instance, you may be only interested in the retention of employees who make it past the 90 day trial period. To do this you can set the month threshold to 3.
