What is meant by population change?
Population undergoes continual change. The number of births and deaths fluctuate over time and people move into, out of and around New Zealand. In the process, the nature of living arrangements and families change, affecting the number and type of families and households, and the needs and expectations of people change. The magnitude of these changes affects the shape, composition and behaviour of the population.
How can population change information be used?
Social, economic and environmental changes are closely linked to population changes. Monitoring population change assists in understanding past responses to and cause of change in New Zealand, as well as future needs of the population, both at the national and the regional level.
Because New Zealand is not isolated from the rest of the world, understanding population change can provide insights into the interaction between New Zealand and other countries. Economic performance is often measured in terms of how characteristics of New Zealand's population compares with those of other countries.
