It has been a long wait for a clear measure of New Zealand's population. The five-yearly Census was ready to be taken in 2011 when the Christchurch earthquake struck. The postponed headcount taken this year produced its figure this week, giving us a population of 4.24 million. It ought to have been more.
The population has grown less in the seven years since the last Census than it did in the five years to 2006. We should be concerned about that; population growth is normally better in periods when the economy is doing well by comparison to other advanced economies, which has been the case since 2008.
New Zealand, Australia and Canada weathered the global financial crisis better than Britain, Europe and the United States. For the past few years, since the slowdown in China halted the Australian mineral boom, New Zealand has looked in better shape than Australia too. So why have not more Kiwis come home?
Were it not for immigration, particularly from Asia, the population would barely be growing. Asians comprise the largest number of foreign-born residents in the latest Census, exceeding those born in Britain or the Pacific Islands. The number of Asian residents has doubled since 1981, comprising one in eight of the population now. Seven years ago the ratio was one in 11.
