The universe defined for this survey included all households living in individual homes in Mozambican territory. It excluded households living in collective homes (barracks, hotels, student residences, etc.), the homeless, and diplomats living in embassies/representations.
The MICS 2008 sample was obtained from the preliminary data and the cartography of the 2007 Census. Selection of the MICS 2008 sample followed a two-stage plan: 1) select the Primary Sampling Units (PSU) or Enumeration Areas (EAs); 2) select households within the sample EAs and, within these, exhaustively select units of analysis (that is, women aged 15–49 and children under five).
Thus, the MICS sample covered 715 PSUs (or EAs) selected systematically, with probability proportional to the size of each urban or rural stratum within each province. In each of the 715 PSUs 20 households were selected, which resulted in a total national sample of 14,300 households. Of the 14,300 households, 6,160 were urban and 8,140 were rural.
The division of the sample by urban and rural stratum within each province is proportional, and the unit of measurement is the number of households in each stratum within each province. The minimum number of households expected in each province was 1,200; exceptions were made for Nampula and Zambézia provinces, with 1,600 households each due to their demographic weight, and Maputo City, with 1,500 households due to the greater variability of its socio-demographic characteristics.
To collect data, the methodology of household interviews was adopted, and three types of questionnaire were used: 1) a questionnaire to gather information on all members of the household and the house; 2) one for women aged 15–49; and 3) one for children under five, administered to mothers or caregivers of all children under five living in the household.
The household questionnaire included the following modules:
The questionnaire for women was administered to all women aged 15–49. The questionnaire had the following modules:
For the questionnaire for children under five, the mothers or caregivers in each household were identified and interviewed. The questionnaire had the following modules:
The three survey questionnaires were based on the MICS3 model questionnaires. Starting with the English version of the MICS3 model, the questionnaires were translated into Portuguese
and put into the Mozambican context. Specific themes were added to meet the country’s needs. The pilot survey was held in April 2008 in Maputo City and in Boane district, Maputo province. Based on the results of the pilot survey, modifications were made to the drafting and translation of the questionnaires.
In addition to administering the questionnaires, the fieldwork teams tested the level of iodine in the kitchen salt in use in households and measured the height and weight of all children under five. Details and conclusions from these measurements are presented in the respective sections of the report.

Training the survey staff
Two regional training sessions were held in Mozambique to train the staff who headed the survey in the province and the technicians responsible for supervising at provincial level. The first
training session ran from 30 June to 25 July in Bilene district, Gaza province, and all the provinces from the south of the country and two from the north took part. The second ran from 14 July to 8 August in the city of Chimoio, in Manica province, and involved all the provinces of the central region and one from the north. The training was managed by members of the MICS central management and included theoretical sessions about interviewing techniques, simulated interviews in the classroom and practical sessions on the ground with households, in Bilene district for the first training session and in Chimoio city and Gondola district for the second. Because of the ethnic and linguistic diversity of Mozambique, all participants were natives of the provinces where they were to work and spoke correctly the dominant languages in these areas.
Organization of fieldwork
The MICS data were collected by 25 teams of interviewers. There were two teams and one supervisor per province, with the exception of Nampula and Zambézia provinces and Maputo City, which each had three teams. The teams consisted of four interviewers, one driver, one person taking measurements, and one controller. In addition to the teams of interviewers, each province had a coverage team, which sought to assess the coverage and quality of information filled out on the questionnaires and to provide feedback for the teams on the ground, so as to improve the quality of the questionnaire information. The coverage team consisted of two interviewers and one driver. The field work began in August 2008 and ended in November of that year. Sending the completed questionnaires from the provinces to the INE headquarters in Maputo was completed in late January 2009.
Data processing
Data processing began in October 2008 and ended in April 2009. Survey processing involved both manual and automatic procedures: receiving and verifying questionnaires, criticism (revision and codification), inputting, editing and analysis of inconsistencies. Data were captured using the interactive software CSPro (Census and Survey Processing System) on 20 microcomputers. Forty data entry operators took part, distributed in two shifts, and a supervisor. To ensure quality control, all the questionnaires were input twice. Throughout the work, procedures and standard programmes developed under the global MICS3 project were used and adapted to the local questionnaire. For cleanness and consistency of data input, the software Stata was used.
Estimate of sampling errors
Since MICS 2008 was a survey by sampling, the results presented in this report are subject to two types of error: sampling errors and non-sampling errors. Non-sampling errors are produced during data collection and processing; sampling errors result from the fact that only a part of the population was interviewed rather than the entire population.
Non-sampling errors include such problems as: failure to question all the women and children selected, errors in formulating the questions and registering the replies, confusion or incapacity of the women in giving information about themselves or their children, and codification or processing errors. Attempts were made to keep this type of error to a minimum by following a series of procedures used in well designed and implemented samples, such as, for example, careful interview design, numerous tests of the questionnaire, intensive training of the interviewers, permanent supervision of the field work, and office review of the questionnaires by the criticism staff. Furthermore, to reduce this type of error, a coverage team was trained to assess the magnitude of such errors, including the coverage of MICS 2008. This team visited all the EAs selected for MICS in all the provinces but the contents or themes were covered by samples.
Appropriate supervision at the stage of data codification and processing, careful cleaning of the archives, feedback to the supervisors, and criticism of the interviewers based on quality control tables also helped minimize errors. The assessment elements available indicate that this type of error was kept within reasonable margins in MICS 2008.
