Migration influencing population
THE
estimated resident population of New Zealand was 4,165,600 at 31
December 2006, according the latest figures from Statistics New Zealand.
The population increased by 45,100 (1.1 per cent) in the December 2006
year, compared with 36,700 (0.9 per cent) in the December 2005 year.
The higher population growth during the December 2006 year was due to a
larger permanent and long-term migration gain and a larger natural
increase (excess of births over deaths).
Permanent and long-term arrivals exceeded departures by 14,600 in the
latest year, compared with a net migration gain of 7,000 in the
December 2005 year. Natural increase was 30,400 in the December 2006
year, which was 700 higher than in the previous December year (29,700).
At 31 December 2006, half New Zealand's male population was aged over
35.0 years, and half the females were over 36.8 years. The median age
has increased by 2.7 years for males and 3.1 years for females between
the 1996 and 2006 December years.
The age composition of New Zealand's population has changed over the
last decade. Between the 1996 and 2003 December years, the number of
children (aged 0-14 years) increased by 18,600 (2.1 per cent) to reach
884,300.
However, since 31 December 2003, the number of children has decreased
to 874,300. This has resulted in an increase of 8,600 children (1.0 per
cent) between December 1996 and 2006. At 31 December 2006, children
accounted for 21.0 per cent of the population. Those aged 15-64 years
accounted for 66.5 per cent of the population.
During the last decade, this age group increased by 12.5 per cent to
2,771,300 in 2006. The 65+ age group grew 20.1 per cent over the same
period, to reach 519,900 at 31 December 2006.
At 31 December 2006, the median age of the population aged 15-64 years
was 38.8 years, up from 36.5 years in 1996. Similarly, the median age
of those aged 65 years and over increased from 73.4 to 74.2 years over
the same decade. |
