Methodology
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 yet for 2018.
