2005-06 Household Expenditure Survey - Cook Island

Abstract
---------------------------

The Cook Islands Household Expenditure Survey (HES) was conducted in 2005-06.
This Household Expenditure Survey (HIES) is a critical component of the work of the Cook Islands Statistics Office. The survey provides major indicators of the economic health of the nation and the well being of its people. For example Cook Islands residents (as opposed to businesses, government or tourists) consume a significant proportion of goods and services available in the Cook Islands. Changes in consumer and household spending patterns reflect changes in the economy and in individual and social behaviour. It provides the data which is necessary for the periodic revision of weights for the Office's Consumer Prices Index and other indices,

The 2005 HES is the third comprehensive survey of household expenditure in the Cook Islands, following on from the 1986 and 1998 surveys. Previously HES were carried out in Rarotonga only.

Geographic coverage
---------------------------

The 2005 HES aimed to cover the entire country however not all households were covered in the survey due to the cost of enumeration in the outer islands. Remote islands that were not surveyed were represented in the survey by nearby islands. For example original plans were to survey Pukapuka and have this island representing Nassau and Suwarrow. The five cyclones that hit Cook Islands in early 2005 left Pukapuka heavily damaged in turn significantly affecting expenditure patterns. As a result, Pukapuka was not enumerated and the Penrhyn and Manihiki samples were increased to cover all the Northern Group.

1. Rarotonga

Southern Group
2. Aitutaki
3. Mangaia
4. Atiu, (to represent the Ngaputoru islands this includes Mitiaro &
Mauke)

Northern Group
5. Penrhyn, Manihiki (to represent Rakahanga, Pukapuka, Nassau and
Suwarrow).

Analysis unit

- individuals
- households

Universe
---------------------------

The scope of the Household Expenditure Survey (HES) was all private households that had been and intended to reside in the Cook Islands for 12 months or more. It did not cover non-private dwellings and institutions.

NOTE:However not all households were covered in the survey due to the cost of enumeration in the outer islands. Remote islands that were not surveyed were represented in the survey by nearby islands.

Kind of data
---------------------------

Sample survey data [ssd]

Sampling procedure
---------------------------

The frame used for the selection of households for the survey was based on the 2001 Census of Population and Dwellings. This list of dwellings was updated for all Census Districts (CDs) to incorporate any changes that may have occurred between the Census and the time of survey. In the Cook Islands Statistics Office (CISO), CDs are used as census collection units and are defined as small geographic units within Administrative Boundaries. There are roughly 100 households in each CD.

The sample strategy used for the survey was a stratified two-stage systematic sample. The first stage involved the stratified selection of islands, and the second stage involved the systematic selection of households within each
selected island.

摘要
---------------------------
库克群岛家庭消费调查（HES）于2005-06年进行。
此次家庭消费调查（HIES）是库克群岛统计局工作的关键组成部分。该调查提供了国家经济健康状况及其人民福祉的主要指标。例如，库克群岛居民（而非企业、政府或游客）消费了库克群岛内大量商品和服务。消费者和 household 支出模式的变动反映了经济、个人及社会行为的变迁。它提供了数据，对于统计局消费者价格指数及其他指数的定期修订至关重要。
2005年的HES是库克群岛家庭消费的第三次全面调查，继1986年和1998年的调查之后。之前，HES仅在拉罗汤加岛进行。
地理覆盖范围
---------------------------
2005年的HES旨在覆盖整个国家，然而，由于外岛统计成本的原因，并非所有家庭都被纳入调查。未进行调查的偏远岛屿由附近的岛屿代表。例如，原计划调查普卡普卡岛，并由该岛代表纳索和苏瓦罗阿。2005年早期库克群岛遭受的五次飓风严重损坏了普卡普卡岛，从而显著影响了支出模式。因此，普卡普卡岛未进行统计，彭林和马尼希基样本增加以涵盖所有北方群岛。
1. 拉罗汤加
南方群岛
2. 艾图塔基
3. 马尼阿
4. 阿图
（代表纳帕托鲁群岛，包括米塔罗和毛基岛）
北方群岛
5. 彭林，马尼希基（代表拉卡哈纳，普卡普卡，纳索和苏瓦罗阿）。
分析单位
---------------------------
- 个人
- household
总体
---------------------------
家庭消费调查（HES）的涵盖范围是所有计划在库克群岛居住12个月或更长时间的 private household。它不包括非私人住宅和机构。
注意：然而，由于外岛统计成本的原因，并非所有家庭都被纳入调查。未进行调查的偏远岛屿由附近的岛屿代表。
数据类型
---------------------------
样本调查数据 [ssd]
抽样程序
---------------------------
用于调查家庭选择框架的是基于2001年人口和住宅普查。该住宅列表已更新，以涵盖普查与调查时间之间可能发生的任何变化。在库克群岛统计局（CISO）中，普查收集单位使用CDs，定义为行政边界内的微小地理单位。每个CD中大约有100户家庭。
调查使用的样本策略是分层两阶段系统抽样。第一阶段涉及岛屿的分层选择，第二阶段涉及在所选岛屿内系统的家庭选择。
