We can influence our income level through a variety of means. Let’s look at the ones tracked by the Census of 2006 – thanks to no right turn for pointing it out. (No Right Turn is coincidentally the first website that comes up when I press the ‘NZ’ button on Safari, so I read him every day)
First – be male*. 5.4% of males earn over $100,000 per year, compared with just 1.4% of females.
Second – be 45-50 years old, or at least in the age-range 40-60. 6.4% of 45-49 year olds earn over $100,000, and at least 5.7% do so in the wider 40-60 range. Pity those 25-29’s (0.9%) and 30-34’s (3.1%).

The double-whammy is that 10.2% of 45-49 year old males and over 8% of all males 35-60 earn over $100,000.
Third – consider yourself a ‘New Zealander’, or at least ‘European’. 3.98% of ‘Europeans’ and 5% of ‘New Zealanders earn over $100,000.
Next – have a Doctorate, or at least a Masters degree. Now we are starting to really improve the odds – 26.2% of those having a doctorate, and 14.3% of those with masters earn over $100,000. If you are male, then that’s 31.1% of Doctorates and 21.24% of Masters degree holders.
You’ll also want to live in the Wellington region, and in particular – in Wellington city. 5.23% of those in Wellington region, and 7.9% of those in Wellington city earn over $100,000 per year.

That 5.23% for Wellington region rises to 28.2% if you also have a Doctorate – but if you do, you’ll probably want to consider living in Southland, where 42.4% of everybody with a Doctorate earn over $100,000.

Oh – but watch out. You see having a Doctorate and living in Southland is no guarantee that you’ll end up with the loot. Consider these Doctorate holders who are living in the top regions, yet earning under $20,000 per annum. Note that you are equally likely to be earning over $100,000 or under $20,000 if you live on the West Coast.
But I’m impressed with the idea of a Doctorate in Gisborne – second highest chance of earning over $100,000, and 0% chance of earning under $20,000. Sign me up! Let me join the other, err, 21 (a number disguised by Statistics NZ) people in that category.

So I live in Wellington – region and city, am male 40-44 (begads!), and have a foreign masters degree – a combination which would make it unlikely for me not to be earning 0ver $100,000. Statistically.
