1 SURVEY DESIGN Appendix B B.1 INTRODUCTION The IDHS obtained data from representative samples of ever-married women and currently married men to: estimate demographic rates, particularly fertility and under-five mortality rates; measure the level of contraceptive knowledge and practice look at key child health indicators including the level of immunizations; the prevalence and treatment of diarrhea and other diseases; and child feeding practices; assess the coverage of maternity care services; explore men s involvement in reproductive health; investigate the direct and indirect determinants that influence the maternal and child health situation. The survey provides estimates at the national and provincial level for all of the above indicators. In each of the five districts in Central Java and the five districts in East Java which are covered in the Safe Motherhood Project, the sample was expanded to allow for estimates with acceptable precision for all of the main variables derived from the household and individual woman interviews. B.2 SAMPLE DESIGN AND IMPLEMENTATION Administratively, Indonesia is divided into 30 provinces. Each province is subdivided into districts (regency in areas mostly rural and municipality in urban areas). Districts are subdivided into subdistricts and each subdistrict is divided into villages. The entire village is classified as urban or rural. The primary objective of the IDHS is to provide estimates with acceptable precision for the following domains: Indonesia as a whole; Each of 26 provinces covered in the survey. The four provinces excluded due to political instability are Nanggroe Aceh Darussalam, Maluku, North Maluku and Papua. These provinces cover 4 percent of the total population. Urban and rural areas of Indonesia; Each of the five districts in Central Java and the five districts in East Java covered in the Safe Motherhood Project (SMP), to provide information for the monitoring and evaluation of the project. These districts are: in Central Java: Cilacap, Rembang, Jepara, Pemalang, and Brebes. in East Java: Trenggalek, Jombang, Ngawi, Sampang and Pamekasan. Appendix B 267

2 The census blocks (CBs) are the primary sampling unit for the IDHS. CBs were formed during the preparation of the 2000 Population Census. Each CB includes approximately 80 households. In the master sample frame, the CBs are grouped by province, by regency/municipality within a province, and by subdistricts within a regency/municipality. In rural areas, the CBs in each district are listed by their geographical location. In urban areas, the CBs are distinguished by the urban classification (large, medium and small cities) in each subdistrict. BPS-Statistics Indonesia (BPS) maintains the list of CBs, which is used as a frame to draw samples for various surveys. The sample developed for the 2002 National Socioeconomic Survey (Susenas) was used as a frame for the selection of the IDHS sample. Household listing was done in all CBs covered in the 2002 Susenas. This eliminates the need to conduct a separate household listing for the IDHS. A minimum of 40 CBs per province has been imposed in the IDHS design. Since the sample was designed to provide reliable indicators for each province, the number of CBs in each province was not allocated proportional to the population of the province nor proportional by urban-rural classification. Therefore, a final weighing adjustment procedure was done to obtain estimates for all domains. The IDHS sample is selected using a stratified two-stage design consisting of 1,592 CBs. Once the number of households was allocated to each province by urban and rural areas, the number of CBs was calculated based on an average sample take of 25 selected households. All ever-married women age in these households are eligible for individual interview. Table B.1 Allocation of census blocks by province Province Number of census blocks 1.

Gorontalo Total 1,592 Eight households in each CB selected for the women sample were selected for male interview. All currently married men age identified in the selected households were interviewed. This sample is designed to provide estimates for the following domains: Indonesia as a whole; Urban and rural areas of Indonesia; Province, for key indicators in the majority of provinces. In each province, the selection of CBs in urban and rural areas was done using multistage stratified sampling. In urban areas, in the first stage, CBs were selected using systematic sampling. In each selected CB, 25 households were randomly selected. In rural areas, the household selection was done in three stages. In the first stage, subdistricts were selected with probability proportional to the number of households. In the second stage, from each selected subdistrict, CBs were selected using systematic sampling. In the third stage, in each cluster, 25 households were randomly selected. 268 Appendix B

3 In each of the 10 districts in Central Java and East Java, clusters were selected systematically with probability proportional to the number of households. In the second stage, in each CB, 25 households were randomly selected. Results of the household sample implementation by urban-rural residence, by province as well as by male and female subsample are shown in Tables B.2.1 and B.2.2. As shown in Table B.2.1, 34,738 households were selecte d for the IDHS. Of these, 95 percent were successfully interviewed, 2 percent were not interviewed because there were found to be vacant, and 2 percent were away during the survey fieldworkers visit. Other reasons for not interviewing households include having no competent respondent in the household, the dwelling was not found or the dwelling had been destroyed. The overall household response rate is 99 percent (see Table B.2.1 for definition). The level of successful household interviews ranges from 88 percent in West Kalimantan to 99 percent in Riau. The response rate is slightly higher in rural than in urban areas. Tables B.2.2 presents the survey coverage for women interviews. Of 29,996 women eligible for individual interview, 98 percent were successfully interviewed, 1 percent were not interviewed because they were not at home (see Table B.2.2 for definition). Urban women are as likely as rural women to be interviewed in the survey. The response rate does not vary much by province. The lowest rate is in West Kalimantan (96 percent), while in North Sumatera, South Sumatera, Central Kalimantan, North Sulawesi, and Central Sulawesi it is almost 100 percent. Table B.3.1 shows 10,877 households were selected for male subsample of the IDHS. This is approximately one in three households selected for the women sample. Ninety-five percent of those households were successfully interviewed, 2 percent were not interviewed because the dweling was vacant and 2 percent were absent during the fieldworkers visit. The overall response rate is 99 percent, ranging from under 88 percent in West Kalimantan to percent in Riau, Central Kalimantan, and Central Sulawesi. Table B.3.2 shows that 8,740 eligible men were identified for individual interview and of these, completed interviews were conducted with 8,310 men, yielding a response rate of 95 percent. The principal reason for nonresponse among eligible men was the failure to find them at home despite repeated visits to the household. The lower response rate for men was due to the more frequent and longer absence of men from the household. The level of successful household interviews among the provinces ranges from less than 90 percent in West Kalimantan, South Kalimantan, East Kalimantan, and South Sulawesi to percent in North Sumatera, West Nusa Tenggara, Central Kalimantan, and Central Sulawesi.

8 B.3 PRETEST BPS piloted the questionnaire, control form, and manuals in August 2002 to detect any possible problems in the translations or flow of the questionnaire, as well as to gauge the length of time required for interviews. Another important objective of the pretest was to gain experience in field operations and interviewing men, because for the first time IDHS included individual interviews with men. The pretest took place in two provinces, Jambi and South Kalimantan. Pretest training took place from August 1-18, 2002 with the last day spent to train the supervisors and editors to perform their tasks. The training was conducted following the IDHS training procedures, including class presentations, mock interviews, field practice and tests. The training included practice interviews using the questionnaire in Bahasa Indonesia and the local dialect. In each province, 12 people were trained, forming two teams, each consisting of one male supervisor, one female field editor, three female interviewers and one male interviewer. All trainees were employees of BPS field offices. Pretest fieldwork lasted for a week (August 22-30, 2002). Fieldwork was conducted in both urban and rural settings. In South Kalimantan, one urban and two rural census blocks were visited. In each census block, 25 households were selected. These households were interviewed using the Household Questionnaires, where all ever-married women age and currently married males age were identified. In all selected census blocks, a total of 150 households were visited, 75 in Jambi and 75 in South Kalimantan. The survey instruments were finalized following discussions with the National Family Planning Coordinating Board and and the Ministry of Health. B.4 TRAINING A total of 530 persons, 362 women and 168 men, participated in the main survey training for interviewers. Training for 23 provinces took place September 30 through October 17, 2002, while for the three new provinces, training was held in February The training was conducted following the DHS training procedures including class presentations, mock interviews, and tests. All of the participants were trained using the Women s Questionnaire. Once the materials for the women interview were completed, the male participants were trained in conducting an interview using the Men s Questionnaire. The training included practice interviews in Bahasa Indonesia and participant s local language. B.5 FIELDWORK The IDHS data was collected by 94 interviewing teams. Each team consisted of one team supervisor, one field editor, three female interviewers and one male interviewer. Field operations took place over a five-and-a-half-month period, from October 21, 2002 to April 9, In most provinces, data collection took a break for at least one month during the Muslim fasting month, which fell in early November through early December In Riau, fieldwork began only in December In three provinces, Bangka-Belitung, Banten, and Gorontalo, training of field staff was in March 2003 and data collection took place in April and May Appendix B B.6 DATA PROCESSING All completed questionnaires for IDHS, accompanied by their control forms, were returned to the BPS central office in Jakarta for data processing. This process consisted of office editing, coding of open-ended questions, data entry, verification, and editing computer-identified errors. A team of about 40 data entry clerks, data editors, and two data entry supervisors processed the data. Data entry and editing started on November 4, 2002 using a computer package program called CSPro, which was specifically designed to process DHS-type survey data. To prepare the data entry programs, two BPS staff spent three weeks in ORC Macro offices in Calverton, Maryland in April 2002.
