Multiple Indicator Cluster Survey 2000 - Gambia

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

The 2000 Gambia MICS survey has been implemented to provide end-decade information on many of the indicators. Information on other indicators will be derived from the vital registration system and various diseases monitoring systems. The Gambia's MICS2 was conducted by the Central Statistics Department in collaboration with other government Departments such as the Department of Social Welfare, Department of Community Development, Department of Water Resources, Women’s Bureau, Department of State for Health and Department of State for Education. Other NGOs such as Gambia Family Planning Association (GFPA) and Gambia German Family Planning Programme also participated. Funding was provided by The Gambia UNICEF office. This report presents results on the principal topics covered in the survey and on the World Summit indicators.

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

Sample Design
The sample for The Gambia Multiple Indicator Cluster Survey (MICS) was designed to provide estimates of health indicators at the national level, for urban and rural areas, and for eight Local government Areas (LGA): Banjul, Kanifing, Brikama, Mansakonko, Kerewan, Kuntaur, Janjanbureh and Basse. The sample was selected in two stages. At the first stage, 128 census enumeration areas were selected with probability proportional to size. After a household listing was carried out within the selected enumeration areas, a systematic sample of 4,528 households was drawn. Because the sample was stratified by LGA, it is not selfweighting. For reporting national level results, sample weights are used. Full technical details of the sample are included in Appendix A of the report.

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

Face-to-face [f2f]

Research instrument
---------------------------

The questionnaires for The Gambia MICS were based on the MICS Model Questionnaire with some modifications and additions. A household questionnaire was administered in each household, which collected various informations on household members including sex, age, literacy, marital status, and orphanhood status. The household questionnaire also includes education, child labour, maternal mortality, water and sanitation, and salt iodisation modules. In addition to a household questionnaire, questionnaires were administered in each household for women age 15-49 and children under age five. For children, the questionnaire was administered to the mother or caretaker of the child. From the MICS model English version, key terms in the questionnaires were translated into four languages: Mandinka, Wollof, Fulla and Jola. The questionnaires were pre-tested during March 2000. Based on the results of the pre-test, modifications were made to the wording and translation of the questionnaires.

Cleaning operations
---------------------------

The data were entered on twelve microcomputers using the Integrated Microcomputer Processing System (IMPS) software and the analysis were done using the SPSS. In order to ensure quality control, all questionnaires were double entered and internal consistency checks were performed. Procedures and standard programs developed under MICS and adapted to the Gambia questionnaire were used throughout. Data processing began in September 2000 and finished in January 2001.

Response rate
---------------------------

Of the 4, 536 households selected for The Gambia MICS sample, 4, 492 were found to be occupied (Table 1). Of these, 4, 478 were successfully interviewed for a household response rate of 99.7 per cent. The response rate was slightly higher in urban areas (99.9 per cent) than in rural areas (99.5 per cent). In the interviewed households, 6, 469 eligible women aged 15-49 were identified. Of these, 5,976 were successfully interviewed, yielding a response rate of 92 per cent. In addition, 3, 849 children under age five were listed in the household questionnaire. Of these, questionnaires were completed for 3, 632 children giving a response rate of 94 per cent.

Data appraisal
---------------------------

The single year age distribution of household members by sex exhibits some distortions centred around age 7 for females and on ages 7, 5, and 8 for males. There appears to be significant heaping of female children on ages 6-8 and perhaps a slight dearth of women ages 15-17. For both sexes, some digit preference is evident for ages ending in 0 and 5, a pattern typical of populations in which ages are not always known. As a basic check on the quality of the survey data, the percentage of cases missing information on selected questions is shown in Table 3. Less than one per cent of household members have missing information on their level of education and zero per cent is missing data on the year of education. Among female respondents, 0.5 per cent did not report a 21 complete birth date (i.e., month and year). Two per cent of women who had a birth in the 12 months prior to the survey did not report the date of their last tetanus toxoid injection. These low levels of missing data suggest that there were not significant problems with the questions or the fieldwork. The data on number of hours for working children age 5-14 and complete birth date for children less than 5 years are the most likely among the selected information to be missing. Approximately three per cent of children are missing this information, which may be the result of women having difficulties in estimating the number of hours work, poor handling of infant welfare cards and absence of mother’s of children during the time of the interview.

摘要
---------------------------
2000年冈比亚多指标聚类调查（MICS）的实施旨在为众多指标提供跨世纪的信息。其他指标的信息将源自生命登记系统和各种疾病监控系统。冈比亚的MICS2由中央统计局与多个政府部门合作开展，包括社会福利部、社区发展部、水资源部、妇女局、卫生部和教育部。此外，冈比亚计划生育协会（GFPA）和冈比亚德国计划生育项目等非政府组织也参与了调查。调查资金由冈比亚联合国儿童基金会办公室提供。本报告展示了调查覆盖的主要主题以及世界峰会指标的结果。
地理覆盖范围

2000年冈比亚多指标聚类调查（MICS）是一项针对家庭、妇女和儿童的全国代表性调查。
分析单位

家庭、妇女、儿童。
数据类型

样本调查数据 [ssd]
抽样程序
---------------------------
样本设计
冈比亚多指标聚类调查（MICS）的样本设计旨在为国家层面、城市和农村地区以及八个地方政府区域（LGA）提供健康指标的估计值：班珠尔、卡尼宁、布里卡马、马纳斯科科、克尔韦安、昆塔乌尔、贾贾纳布雷赫和巴塞。样本在两个阶段进行选择。在第一阶段，根据规模比例选择了128个普查区。在所选普查区内进行家庭列表后，抽取了4,528个家庭的系统样本。由于样本按LGA分层，因此不是自加权。为了报告国家层面的结果，使用了样本权重。报告中附录A包含了样本的完整技术细节。
数据收集方式

研究工具
---------------------------
冈比亚MICS的调查问卷基于MICS模型问卷进行了一些修改和补充。在每个家庭中进行了家庭问卷，收集了有关家庭成员的各种信息，包括性别、年龄、识字情况、婚姻状况和孤儿状况。家庭问卷还包括教育、儿童劳动、孕产妇死亡率、水和卫生以及食盐碘化模块。除了家庭问卷外，还对每个家庭中的15-49岁妇女和五岁以下儿童进行了问卷。对于儿童，问卷由母亲或看护人填写。从MICS模型的英语版本中，问卷中的关键术语被翻译成了四种语言：曼丁卡语、沃洛夫语、富拉语和约拉语。问卷在2000年3月进行了预测试。根据预测试的结果，对问卷的措辞和翻译进行了修改。
数据清洗操作
---------------------------
数据使用集成微机处理系统（IMPS）软件在十二台微型计算机上录入，并使用SPSS进行分析。为了确保质量控制，所有问卷都进行了双录入，并执行了内部一致性检查。在整个过程中使用了MICS下开发的程序和标准程序，并适应了冈比亚问卷。数据处理始于2000年9月，并于2001年1月完成。
响应率
---------------------------
在为冈比亚MICS样本选取的4,536个家庭中，有4,492个被发现是有人居住的（见表1）。其中，4,478个家庭成功接受了访谈，家庭响应率为99.7%。城市地区的响应率（99.9%）略高于农村地区（99.5%）。在受访的家庭中，确定了6,469名符合条件的15-49岁妇女。其中，5,976名妇女成功接受了访谈，响应率为92%。此外，在家庭问卷中列出了3,849名五岁以下儿童。其中，3,632名儿童的问卷被完成，响应率为94%。
数据评估
---------------------------
按性别划分的家庭成员年龄分布的单一年度显示，女性在7岁左右存在一些扭曲，而男性则在7岁、5岁和8岁存在。女性儿童在6-8岁之间似乎存在显著集中，也许15-17岁的女性略有短缺。对于两种性别，年龄以0和5结尾的数字偏好明显，这是人口中年龄不一定总是可知的典型模式。作为对调查数据质量的初步检查，表3显示了选定问题缺失信息的案例百分比。不到1%的家庭成员在他们的教育水平上缺失信息，而关于教育年份的信息缺失率为零。在女性受访者中，0.5%的人未报告完整的21岁出生日期（即，月份和年份）。在调查前12个月内分娩的2%的妇女未报告最后一次破伤风类毒素注射的日期。这些低水平的缺失数据表明，在问题或实地工作中并未出现重大问题。关于5-14岁工作儿童的工作小时数以及5岁以下儿童的完整出生日期是可能缺失的信息中最有可能的。大约3%的儿童缺失这些信息，这可能是由于妇女在估计工作时间上的困难、婴儿福利卡的糟糕处理以及访谈期间儿童母亲的缺席所致。
