Standard for population terms will help you understand and use Statistics NZ's population measures.
Historically, population data referred to the people present in an area at a given time. For most geographic areas, this was similar to the number of people who lived there.
However, as internal and international travel has increased, so has the number of people who are away from their usual residence. There is a need for population data about the people who usually live in an area at a given time, as this is often more relevant for many purposes (such as setting electoral boundaries and planning community services).
This document defines and explains the three main population measures Statistics NZ produces:
Anyone presenting population data must use the full standard terms for these measures, so users know which measure has been used. This will prevent confusion when they compare data from different sources. Standard for population terms tells you how to use the terms correctly.
