The Social Report monitors outcomes for
the New Zealand population. This section contains background
information on the size and characteristics of the population to
provide a context for the indicators that follow.
Population size and growth
New Zealand's resident population reached 4 million in April
2003 and was estimated to be 4.12 million at the end of December 2005.
During 2005, the population grew by 37,000 or 0.9 percent.
This was a lower rate of growth than that recorded in 2004 (44,500 or
1.1 percent) and lower than the average annual increase during the
10-year period to December 2005 (41,400 or 1.1 percent).
Under 2004-based medium population projection assumptions, the
population is expected to grow by an average of 0.8 percent per year
between 2005 and 2011. Natural increase (births minus deaths) will
account for four-fifths of this growth, and net migration the remaining
fifth. Assuming net migration of 10,000 people per year after that, the
growth rate is expected to slow to 0.7 percent per year for the next 15
years. Such a growth rate would add around 634,000 people to the
population between 2005 and 2026.5
