Footnotes for The City's People
The 1997 population estimate for Christchurch City was prepared by Statistics New Zealand.
All other sections of this report refer to the actual 1996 usually resident census count.
Although it is clear that migration has been the major contributor to City growth it is difficult to paint an accurate picture of its annual volume and content. This is because of the way in which migration statistics are collected. For internal migration, the five yearly Census of Population and Dwellings is the key information source. No reliable annual internal migration figures for Christchurch are available. Data from arrival and departure cards filled in when people arrive and leave the country is the main source of international migration figures. These cards outline peoples immediate intentions but not necessarily their ultimate destination. For this reason it is likely that international migration figures from this source (shown in the international migration section) understate the level of migration to the City.
Statistics New Zealand have also prepared population projections using the adjusted 1996 base. See the Hot off the Press publication ‘Sub-national Resident Population Projections 1996 Base’ 30 October 1997.
For more information refer to City of Christchurch City Plan, Volume 2: The Statement of Objectives, Policies and Methods (publicly notified June 24 1995).
The actual number of children grew during the early 1990s in response to a brief increase in births.
Excluding non private dwellings such as boarding houses and homes for the elderly.
A ‘household’ for census purposes comprises a person or persons who reside in a private dwelling.
A family is defined as either a couple (from a legal or a defacto marriage) with or without a child (or children) who usually live in the same household.
The ‘couples’ family type include all couples who have chosen to remain childless, as well as younger couples who have not yet had children and older couples who have reached the ‘empty nest’ stage ie their children have grown up and left home.
Christchurch City’s labour force includes people aged over 15 years who regularly work full or part time and those who are unemployed but are actively looking for either full or part time work.
Data on sources of income include all the persons who specified each income source, whether as their only source or one of several sources. Where a person reported more than one, they have been counted in each applicable source.

Crime statistics relate to the Christchurch Police District.
Road casualty statistics refer to the number of people injured during crashes and the severity of those injuries. This differs from road crash statistics which relate to the number and severity of crashes involving injury.
This crash type includes most collisions between vehicles at intersections and driveways.
Traffic crashes generally have more than one contributing factor. Therefore the number of crashes with each factor shown below, when added, will be greater than the total number of crashes in the City.
1994 mortality data was the latest information available at the time this document was written.
Despite this improvement, levels of life expectancy in New Zealand remain below those in Australia, Japan and many European countries. In 1994, Japan has the highest life expectancy at birth for both men and women, 76.6 and 83.0 years respectively.
