APPENDIX A. SAMPLE DESIGN

The sample for the Multiple Indicator Cluster Survey was designed to provide estimates on a large number of indicators on the situation of children and women at the national level; for areas of residence of Iraq represented by rural and urban (metropolitan and other urban) areas; for the 18 ; and also for metropolitan, other urban, and rural areas for each governorate.

Thus, in total, the sample consists of 56 different sampling domains, that includes 3 sampling domains in each of the 17 governorates outside the capital city (namely, a “metropolitan area domain” representing the governorate city centre, an “other urban area domain” representing the urban area outside the governorate city centre, and a “rural area domain”) and 5 sampling domains in Baghdad (namely, 3 metropolitan areas representing “Sadir City”, “Resafa side”, and “Kurkh side”, an other urban area sampling domain representing the urban area outside the three Baghdad governorate city centres, and a sampling domain comprising the rural area of Baghdad).

A multi-stage, stratified cluster sampling approach was used for the selection of the survey sample. Sample Size and Sample Allocation

The adequate sample size ns for each of the 56 sampling domains, is 324 households. Thus, the target sample size for the Iraq MICS was calculated as 18144 households ( = 56 ns ). The following formula was used to estimate ns

Z 2 ⋅ P (1 − P ) ⋅ deff 1−α n = 2 s E 2 where

The required sample size for each sampling domains, n = s expressed as the number of households

Z1- a /2 = z-value determined by the confidence level = 1.96 for 95% confidence limits deff = design effect = 2 p = The estimate of the proportion = 0.5 (assumed maximum) E = The total width of the expected confidence interval = 0.077 therefore,

(1.96) 2 0.5(0.5)2 n = = 324 s (0.077 ) 2

Sample sizes and terms of error for all sampling domains, governorates, and total are shown in Table SD.1. Terms of error are being decreased to less than 7.7% for the governorate and national level, urban; rural; and total.

The allocation of the Iraq MICS3 survey is not self weighting due to the requirement of reporting on different levels of representation, as indicated above.

Iraq Multiple Indicator Cluster Survey Final Report, 2006  The Sample size of each of urban (other) and rural area is allocated among districts with respect to the population in each of urban and rural area. Table SD.2 shows the details of sample allocations. These calculations are based on a cluster size of 6 households. Sample has adjusted internally in order to get integer number of clusters i,e applicable to divide by 6. Sampling Frame The sample frame for the MICS-3 survey is divided into two separate parts. The first is derived from the 1997 census of Iraq, and covers the 15 Southern governorates. The second is based on information provided by the statistical offices in the three governorates of Kurdistan region, with a very similar administrative organization of the first part.

The census list is a complete listing of individuals following the administrative organization of the census. It is organized as a file with the following variables:

The lowest area unit is the majal, which may be a full geographical street, but is more often a part of such a street. These units are usually quite small (less than 30 households) and can therefore not be used directly as sampling clusters in the first stage of the sample. It is often impossible to draw the second stage sample

Variable Explanation Muhafaza Governorate, region Qadha District Nahiya Municipality Area Urban rural identifier (1=urban, 2 rural, 3 nomad) Block. Group of either villages or majalas, depending on Block whether it is in rural or urban areas, respectively. Village – Only used in rural areas, may contain one or more Qarya blocks Majal Lowest administrative level, for the census purposes Street Street number Building Building number within street Famseq Family sequence number within street

of households from these units, due to two facts . First, that they contain too few households, and second that the population growth and migration, it is likely that the 1997 census does not accurately represent the population distribution of Iraq. The relisting of majals to some extent corrects this, but parts of the population are most likely not covered by the census are likely to be missed by the survey. The majals therefore have to be merged. PSUs are constructed by merging majalas and sometimes blocks. This is done by computer, and may lead to some PSUs being split into non-contiguous locations. The following diagram shows the structure of the sample frame, and the manner of merging the majals.

 Iraq Multiple Indicator Cluster Survey Final Report, 2006 Approximated PSU size is 70 – 100 HHs ( two – four majals ). Sample selection procedures a. Primary Sampling Units Selection Taking in consideration sample allocations, table 2; and no. of sample clusters, table 3, the primary sampling units construction and selection are done by,

1. Listing the majals, for each location, according to the administrative arrangements, starting from majal no.1 of block no.1, and ending with the last majal of the last block in the location.

2. Constructing the PSUS for each location by merging 2-4 neighboring majals. The PSU size should not exceed 100 HHs. The expected PSU size lies between 70- 100 HHS.

3. Selecting a number of PSUS, equal to the required number of clusters in each location, by using the PPS procedures. b. Segmenting of PSUs In some cases it may be necessary to segment PSUs after the mapping and listing procedures. This can be due to several reasons, like:

1. The PSU is so large (in terms of households) that it is impractical to list it completely

2. The PSU is not necessarily very large, but the arrangement of the housing is so complex that it is deemed prudent to only list a comparatively small geographic area.

3. The merging of the households has led to a PSU being geographically very spread out, for instance that it contains two villages that are very far from each other.

Iraq Multiple Indicator Cluster Survey Final Report, 2006  The three cases will be treated as follows:

The first case of large PSUs, will be split according to the following table: MICS-3 Splitting rules # of households PSU Split into this number of clusters 100-200 2 201-300 3 ... and so on

In order to segment, the boundaries of the required number of segments within the PSU should be determined. Then the size of segments (number of households) should be quick-counted and the selection of the segments should be done using PPS selection. The precise procedure is described in the mapping and listing manual.

The second case of very difficult PSUs, might arise in for instance old parts of towns. One should not reduce the expected number of households in the PSU to less than 70. The decision to split must be taken by the sampling team, not the local field staff.

The third case of villages that turns out to be geographically far apart, is not necessarily a problem, because the sample will be spread out all over the governorate. It is therefore quite possible that the field teams will visit close to all selected villages. However, if it is necessary to segment the PSU, the segments will be villages, and the selection of one village will be carried out by using PPS selection. Again, the decision to split must be taken by the sampling team, not the local field staff. c. Mapping and listing of PSUs and segments The selected PSUs weremapped (or maps updated) and re-listed. The purposes of the mapping and re- listing are two: first, to enable selection of households, and second, to enable interviewers to locate the selected households.

The mapping and listing is described in detailed in the mapping and listing manual. In some cases, as noted above, it was necessary to segment the PSU. All households within a selected PSU, or segment of PSU, were listed.

In conjunction with the mapping, exact geographical coordinates (longitude and latitude) of the PSU were determined using a GPS-receiver. The measurement was taken approximately in the middle of the PSU. The procedure is described in the IMIRA GPS-manual (Iraq Living Conditions Survey, 2004). d. Selection of households Linear systematic sampling is used to select six households from the list of re-listed households. The sample is considered as a sample of households, not dwellings. The selected households is considered as a “ cluster “ ( table 3 ). e. Substitution No substitution of selected PSUs or households is to take place. f. Additional households in dwelling units The list of households is intended to be a complete list of households in a PSU. Therefore, if two households are found in one dwelling unit, only the one the interviewer has been instructed to interview should be interviewed. The other household should in principle be listed separately on the household list, and therefore has an independent chance of being included in the sample.

Iraq Multiple Indicator Cluster Survey Final Report, 2006 13 Calculation of Sample Weights

The Iraq Multiple Indicator Cluster Survey sample is not self-weighted. Essentially, by allocating equal numbers of households to each of the sampling domains, different sampling fractions were used in each sampling domain since the size of the sampling domains varied. For this reason, sample weights were calculated and these were used in the subsequent analyses of the survey data.

The major component of the weight is the reciprocal of the sampling fraction employed in selecting the number of sample households in that particular sampling domain:

Wh = 1 / fh The term fh, the sampling fraction at the h-th stratum, is the product of probabilities of selection at every stage in each sampling domain:

fh = P1h * P2h * P3h

where Pih is the probability of selection of the sampling unit in the i-th stage for the h-th sampling domain.

Since the estimated numbers of households per enumeration area prior to the first stage selection (selection of primary sampling units) and the updated number of households per enumeration area were different, individual sampling fractions for households in each enumeration area (cluster) were calculated. The sampling fractions for households in each enumeration area (cluster) therefore included the probability of selection of the enumeration area in that particular sampling domain and the probability of selection of a household in the sample enumeration area (cluster).

A second component which has to be taken into account in the calculation of sample weights is the level of non-response for the household and individual interviews. The adjustment for household non-response is equal to the inverse value of:

RR = Number of interviewed households / Number of occupied households listed

After the completion of fieldwork, response rates were calculated for each sampling domain. These were used to adjust the sample weights calculated for each cluster. Response rates in the Iraq Multiple Indicator Cluster Survey are shown in Table HH.1 in this report.

Similarly, the adjustment for non-response at the individual level (women and under-five children) is equal to the inverse value of:

RR = Completed women’s (or under-five’s) questionnaires / Eligible women (or under-fives)

Numbers of eligible women and under-five children were obtained from the household listing in the Household Questionnaire in households where interviews were completed.

The unadjusted weights for the households were calculated by multiplying the above factors for each enumeration area. These weights were then standardized (or normalized), one purpose of which is to make the sum of the interviewed sample units equal the total sample size at the national level. Normalization is performed by multiplying the aforementioned unadjusted weights by the ratio of the number of completed households to the total unadjusted weighted number of households. A similar standardization procedure was followed in obtaining standardized weights for the women’s and under-five’s questionnaires. Adjusted (normalized) weights varied between 0.110 and 3.721 in the 56 sampling domains.

Sample weights (Table SD.4) were appended to all data sets and analyses were performed by weighting each household, woman or under-five with these sample weights.
