Jean Balchin Apr 12, 2018

According to a study published in the BMJ today, a significant increase in cigarette prices would aid millions of people around the world avoid poor health and extreme poverty.

Population and real GDP per capita - The Dismal Science

Michael Reddell Apr 09, 2018

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

Immigration policy and emissions targets - The Dismal Science

Michael Reddell Oct 01, 2017

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

Wellington…still growing sluggishly - The Dismal Science

Michael Reddell Aug 02, 2016

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

How has our population grown? - The Dismal Science

Michael Reddell May 31, 2016

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 wrongheaded call for an ever-bigger population - The Dismal Science

Michael Reddell May 28, 2016

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

Octopus and squid populations are booming – here’s why - Guest Work

Guest Author May 25, 2016

By Alexander Arkhipkin, University of Aberdeen Squid, octopus and cuttlefish populations are booming across the world. These fast-growing, adaptable creatures are perfectly equipped to exploit the gaps left by extreme climate changes and overfishing, according to a study colleagues and I published in the journal Current Biology. Humans have reached and in many cases surpassed sustainable fishing … Read More

Societal trends - Ariadne

Robert Hickson Mar 30, 2016

Hans Rosling, of Gapminder fame, and perhaps the world’s most enthusiastic statistician, has an hour long video making the case that increasing global population levels aren’t fundamentally a prelude to disaster. (You can read a synopsis here). You can also save time by looking at these shorter videos showing the key trends of … Read More
