Brian Gill The fate of rats on a tiny New Zealand island is a story to retell as the world’s experiment with unlimited growth of human numbers threatens ruin. The world has too many people. As if more than 7,260 million souls are not enough, the population is in the dreaded phase of exponential growth, rocketing uncontrolled and uncontrollably to … Read More

The study concluded that people on low incomes have the most to gain, and the researchers argue that modest action by many governments “could yield unprecedented health gains and poverty reduction.” Smoking … Read More

I noticed a few comments to another of my posts about possible links between population size and economic performance. My working assumption is that, on average, across all countries, there isn’t any such relationship. Apart from anything else, if there were a positive relationship – that was more than chance – it would suggest that two countries … Read More

I’ve written a few posts in recent months about the connections between our immigration policy – materially boosting our population growth rate – and New Zealand greenhouse gas emissions (for example here and here). New Zealand is unusual because, as the Ministry for the Environment (MfE) has highlighted: • we have a fairly high rate of trend population growth, … Read More

It is the costs of meeting … Read More

There was an annoying story on the front page of the Dominion-Post this morning. The online version of the story is headed “The big squeeze: Wellington’s population could almost double in the next 30 years”, a proposition which appears to be based on nothing more than annualizing last year’s estimated population growth for the Wellington city area. I … Read More

New Zealand’s population is estimated to have risen by 11.8 per cent in the last decade (much of it in the last three years). The starting point for that estimate is reasonably well-anchored: I used the population numbers for the March quarter of 2006, and the 2006 Census happened in that month. The end-point (March 2016) is only a Statistics … Read More

The Herald’s editorial on Saturday was headed “Population growth is powering NZ economy”. It isn’t just a statement of the rather obvious, that a rapid growth in the population – particularly unexpectedly rapid growth – boosts total GDP. When there are more people, they all need to consume stuff, and they need houses, schools, shops, roads, offices etc. And … Read More
