The objectives of the survey were:
(a) to obtain information on the opinions of residents in the Christchurch City Council area on the performance of the services supplied by the Christchurch City Council (CCC);
(b) to ascertain residents' use of and satisfaction with, a range of Christchurch City Council facilities and services;
(c) to measure changes from year to year, over a three year period beginning April 1994, extended to a fourth year for 1997
The survey has been designed to produce statistical indicators which will provide measures of performance as set down in the Council's performance indicators for specified service delivery areas.
The statistical indicators combined with additional factors will aid Council decision making and policy formulation, and help to determine priorities for resource allocation.
The population for the survey was defined as all people aged 18 or over:
The following people were excluded:
A further population of interest for some items was children aged under 18 living in permanent private dwellings in the Christchurch area. Children were not separately surveyed; respondents were asked to give information about the children living in their household.
The sample design was a three-stage cluster design. First clusters of dwellings within Christchurch were chosen, then dwellings within those clusters and finally a respondent within each dwelling. The clusters were chosen using the Department's multi-purpose household survey facility. The clusters in this case correspond to Departmental primary sampling units (PSUs). New Zealand is divided up into 18,581 PSUs. Ninety PSUs were randomly selected within CCC boundaries.
For each selected PSU, every private dwelling was identified and listed to determine the total number of dwellings per PSU. To allow for ineligibles, unoccupied dwellings and households with no-one resident in the CCC area for the last twelve months and refusals, 1,168 households were selected (second stage of sampling). Given the Department's normal assumptions of ineligibles and non response it was expected that the achieved sample size would be 750-760 (this would give a sample error of the
order of 3% at the 90% confidence level).
The third stage of sampling was the selection of one respondent from every eligible household. This is discussed in the Fieldwork section.
