Experience of the workforce over time

The average experience of the workforce has lowered since 2011. This is caused by the growth in trades sectors seeing an influx of new workers with no experience. While the number of workers with 9+ years of experience has grown from 38,000 in 2011 to 52,000 in 2018 the number of workers with 0 - 1 years experience has over shadowed this growing from 44,000 workers in 2011 to 79,000 to 35,000.

From workers found in IRD tax records who work at least three months in a year we determine the experience these workers have had in their sector in the 10 years prior to their work date.

For self-employed workers we can usually only see income on a yearly basis, thus employment defined in 12 month blocks meaning few are found with 0 years (0 - 11 months) experience.

Note that self-employed tax records are not complete for 2018.
