Multiple Indicator Cluster Survey 2005
For tabulation and analysis SPSS versions 13.0 and 14.0 were used. Version 13.0 was originally used for all tabulation programs, except for child mortality. Later version 14.0 was used for child mortality, data quality tabulations and other analysis activities.
After transferring all files to SPSS, certain variables were recoded for use as background characteristics in the tabulation of the data, including grouping age, education, and geographic areas as needed for analysis. In the process of recoding ages and dates some random imputation of dates (within calculated constraints) was performed to handle missing or "don't know" ages or dates.
Additionally, a wealth (asset) index of household members was calculated using principal components analysis, based on household assets, and both the score and quintiles were included in the datasets for use in tabulations. Conventionally, household economic status is being is defined by the data of household income and expenditure. This conventional method of data collection is time consuming (each household member is asked numerous questions by each of income sources). Besides such a method can result in incompleteness of data (interviewee may be unaware of income and expenditures of other members) and be challenged by irregularity of household economic activities and difficulties of capturing the higher incomes. Therefore, the current survey has estimated the indicator “wealth Index” to measure the household wealth which can be captured by a few and simple questions. For this purpose, it is quite possible to use the questions asked to measure other indicators (drinking water, sanitation facilities, housing type, access to electricity). One advantage of this index is to lessen the data effect of seasonal and temporary income sources as the index concentrates on assets or capitals accumulated over the longer period. (Rutstein & Johnson, 2004). The survey results were estimated by five equally weighted groups of wealth index. This includes the indicators of household type, condition, drinking water, sanitation facility, access to electricity, household consumerables (communications and transportation means, household electrical appliances). Using these indicators, each household was then weighted by the number of household members, and the household population was divided into five groups of equal size, from the poorest quintile to the richest quintile, based on the wealth scores of households they were living in. Total households were put in five groups with the following categories: poorest (I), second (II), middle (III), fourth (IV), richest (V).
The survey data has been disaggregated by national average, regions, urban and rural areas with household location and estimated by women education level and five wealth groups of household with equal weighting.
