It is all about how you calculate it as to what number you arrive at. Statistics New Zealand calculates the gender wage gap by comparing the hourly earnings, rather than weekly/yearly earnings. This helps to take into account the fact that women tend to work less hours (for various reasons, and is a completely different conversation). [0] Interestingly, the gap when comparing the entire workforce with this measure is 10% in NZ, and comparing full time employment drops to 5.6% (the lowest in the OECD) [1]. One thing that needs to be considered when comparing the wage gap is that >90% of workplace fatalities are men [2], and that men tend to work much more physical jobs, causing of greater rate in workplace injuries and problems later in life, just think of how many older people you know with hearing loss from work, and how the vast majority of them are men.
