Integrated Household Budget Survey 2005-2006 - Kenya

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

The Kenya Integrated Household Budget Survey (IHBS) 2005-2006, was designed to capture data that would be used to update poverty, welfare statistics and employment statistics, derive the Consumer Price Index (CPI) and revise the national accounts information.

IHBS also aimed at providing data on socio-economic aspects of the Kenyan population including education, health, energy, housing, water and sanitation. This data is critical to the government and private sector for the purpose of guiding investment and national development policy decisions. The survey was carried out by the Kenya National Bureau of Statistics (KNBS) with technical and financial assistance from the Department for International Development (DfID), the United States Agency for International Development (USAID), the European Union (EU), the Danish International Development Agency (DANIDA), The World Bank and the United Nations Development Program (UNDP).

The survey covered all the 70 districts including rural and urban clusters with data being collected from all arid and semi-arid areas for the first time in a decade. All surveyed households were captured using the Geographical Positioning System (GPS) which made it possible to identify the precise geographical location of households. The survey was conducted over a period of 12 months, which covers all possible seasons, as in contrast to previous surveys where the longest survey conducted by the Bureau was for three (3) months.

Sample survey data [ssd]

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

The Kenya National Bureau of Statistics (KNBS) has established the National Sample Survey and Evaluation Program (NASSEP IV) sampling frame based on the 1999 Population and Housing Census (PHC). The sample design of the IHBS 2005-06 is based on this frame. The survey drew a sample of clusters from the set of 540 urban clusters and the 1,260 rural clusters under NASSEP IV sampling frame.

The IHBS 2005-06 covered a total of 1,343 clusters with a total sample of 13,430 households, stratified by district and by urban/rural. In the first stage, using the KNBS Master Sample (NASSEP IV), 1,343 clusters were selected with equal probability within a district. In the second stage, 10 households were selected with equal probability in each cluster.

A total sample of 13,430 households (10 households in each of 1,430 Primary Sampling Units (PSU) were allocated into 136 explicit strata (the urban and rural sections of each of Kenya's 69 districts, except in Nairobi and Mombasa, which are wholly urban). The 1,343 clusters required by the IHBS were selected from the Central Bureau of Statistics (CBS) 1,800-cluster master sample. This selection was done with equal probability within each stratum, except for the six districts that contain urban areas qualified as municipalities. In these districts, the urban part of the sample was further stratified into six groups (five socio-economic classes in the municipality itself and other urban areas in the district).

Sampling deviation
---------------------------

From the design sample of 1,343 clusters, only 1,339 clusters were covered the remaining 4 clusters were not covered due to inaccessibility and security issues.

Mode of data collection
---------------------------

Face-to-face [f2f]

Research instrument

The following questionnaires were administered during the survey:
1. Household Questionnaire
2. Community Questionnaire
3. Diary Questionnaire

摘要
---------------------------
肯尼亚综合家庭预算调查（IHBS）2005-2006，旨在收集用于更新贫困、福利和就业统计数据的资料，推导消费者价格指数（CPI）并修订国民账户信息。
IHBS亦旨在提供关于肯尼亚人口社会经济方面的数据，包括教育、健康、能源、住房、水和卫生等。这些数据对于政府及私营部门在指导投资和制定国家发展政策决策方面至关重要。该调查由肯尼亚国家统计局（KNBS）实施，并得到国际发展部（DfID）、美国国际开发署（USAID）、欧盟（EU）、丹麦国际发展署（DANIDA）、世界银行和联合国发展计划署（UNDP）的技术和财政援助。
调查覆盖了包括农村和城市聚居地在内的所有70个区，首次在十年内收集了所有干旱和半干旱地区的数据。所有调查家庭均使用地理定位系统（GPS）进行定位，从而能够确定家庭的精确地理位置。调查历时12个月，覆盖了所有可能的季节，与之前国家统计局最长进行的为期三个月的调查形成鲜明对比。

抽样程序
---------------------------
肯尼亚国家统计局（KNBS）根据1999年人口和住房普查（PHC）建立了国家样本调查与评估计划（NASSEP IV）抽样框架。IHBS 2005-06的样本设计基于此框架。调查从NASSEP IV抽样框架中的540个城市聚居地和1260个农村聚居地中抽取了样本。
IHBS 2005-06总共覆盖了1,343个聚居地，样本总数为13,430个家庭，按区和城乡进行分层。在第一阶段，使用KNBS主样本（NASSEP IV），在区内以等概率选择了1,343个聚居地。在第二阶段，在每个聚居地内以等概率选择了10个家庭。
总共13,430个家庭（在1,430个一级抽样单位（PSU）中的每个PSU有10个家庭）被分配到136个明确分层中（肯尼亚69个区中的城市和农村部分，内罗毕和蒙巴萨除外，因为它们完全是城市）。所需的1,343个IHBS聚居地从国家统计局（CBS）的1,800个聚居地主样本中选择。该选择在每个分层内以等概率进行，但六个包含城市区域的地区除外。在这些地区，样本的城市部分进一步分层为六个组（市政区的五个社会经济阶层和其他地区）。
抽样偏差
---------------------------
从设计的1,343个聚居地样本中，只有1,339个聚居地被覆盖，剩余的4个聚居地由于不可及和安全问题而没有被覆盖。
