----> Iraq Household Socio Economic Survey (IHSES) Series Information:
The Republic of Iraq was once considered a leader in household expenditure and income surveys. Its first was conducted in 1946, with follow-up surveys in 1954 and 1961. After the establishment of the Central Statistical Organization (CSO, the precursor to COSIT), household expenditure and income surveys were carried out every three to five years (in 1971/1972,1976, 1979, 1984/1985, 1988, and 1993), covering all Iraqi governorates (except the 1993 survey, which could not cover the three governorates in Kurdistan Region of Iraq-Sulaimaniya, Erbil, and Duhouk). At the beginning of July 2002, CSO began a socio-economic household survey for 2002/2003 that again excluded those in Kurdistan Region. The survey was designed for a full year, but CSO lost most of its survey questionnaires and the database because of the war and its aftermath. The only usable data were for the months of July, August, and September 2002.
With no complete household or expenditure surveys undertaken in more than 14 years, the Central Organization for Statistics and Information Technology (COSIT) and the Kurdistan Region Statistics Organization (KRSO) launched fieldwork on the Iraq Household Socio-Economic Survey (IHSES) on November 1, 2006. The survey was carried out over a full year, covering all governorates including those in Kurdistan Region.
The World Bank provided financial support in addition to technical consultation in defining project objectives, the questionnaire, sample design, and the output tables. The Bank also provided substantial technical support for capacity building of COSIT and KRSO staff involved in fieldwork implementation, preparation of data entry programs, and analysis of the survey indicators using the Statistical Package for the Social Sciences (SPSS).
The Iraqi side prepared the fieldwork implementation plan and mechanism; contributed to the questionnaire and sample design; selected the households; prepared and trained the fieldworkers; updated the lists and maps; and implemented the fieldwork, data entry, and results generation.
Iraq Household Socio Economic Survey (IHSES) constitutes the first component of the Poverty Reduction Strategy Project, which the Republic of Iraq is implementing in cooperation with the World Bank. The overall project consists of four components: (i) data collection (IHSES), (ii) poverty and inequality assessment, (iii) analysis of impact of proposed policies, and (iv) a poverty reduction strategy.

----> Overview of the Iraq Household Socio Economic Survey (IHSES) 2012:
Iraq is considered a leader in household expenditure and income surveys where the first was conducted in 1946 followed by surveys in 1954 and 1961. After the establishment of Central Statistical Organization, household expenditure and income surveys were carried out every 3-5 years in (1971/ 1972, 1976, 1979, 1984/ 1985, 1988, 1993, 2002 / 2007).
Implementing the cooperation between CSO and WB, Central Statistical Organization (CSO) and Kurdistan Region Statistics Office (KRSO) launched fieldwork on IHSES on 1/1/2012. The survey was carried out over a full year covering all governorates including those in Kurdistan Region.
The survey has six main objectives. These objectives are:
- Provide data for poverty analysis and measurement and monitor, evaluate and update the implementation Poverty Reduction National Strategy issued in 2009.
- Provide comprehensive data system to assess household social and economic conditions and prepare the indicators related to the human development.
- Provide data that meet the needs and requirements of national accounts.
- Provide detailed indicators on consumption expenditure that serve making decision related to production, consumption, export and import.
- Provide detailed indicators on the sources of households and individuals income.
- Provide data necessary for formulation of a new consumer price index number.
The raw survey data provided by the Statistical Office were then harmonized by the Economic Research Forum, to create a comparable version with the 2006/2007 Household Socio Economic Survey in Iraq.
Harmonization at this stage only included unifying variables' names, labels and some definitions.
See: Iraq 2007 & 2012- Variables Mapping & Availability Matrix.pdf provided in the external resources for further information on the mapping of the original variables on the harmonized ones, in addition to more indications on the variables' availability in both survey years and relevant comments.

Version
V1: An inter-year harmonized version of the survey dataset, with Iraq Household Socio Economic Survey 2007, produced by the Economic Research Forum for dissemination.
2016-09
The raw data of the Iraq Household Socio Economic Survey (IHSES) provides valuable information on indicators related to human development. Addition to provide integrated systematic data for the assessment of the family socio- economic situation, including data regarding time use by individuals.
The raw data of Iraq Household Socio Economic Survey (IHSES) 2012 was harmonized with that of Iraq Household Socio Economic Survey (IHSES) 2007, by the Economic Research Forum, to ensure surveys' consistency, and aiming at creating a database of comparable health measurements on the country level for two different years 2007 & 2012.
All documentation available for the original survey provided by the Statistical Office, and for the harmonized datasets produced by the Economic Research Forum, are published.

Sampling
----> Design:
Sample size was (25488) household for the whole Iraq, 216 households for each district of 118 districts, 2832 clusters each of which includes 9 households distributed on districts and governorates for rural and urban.
----> Sample frame:
Listing and numbering results of 2009-2010 Population and Housing Survey were adopted in all the governorates including Kurdistan Region as a frame to select households, the sample was selected in two stages:
Stage 1: Primary sampling unit (blocks) within each stratum (district) for urban and rural were systematically selected with probability proportional to size to reach 2832 units (cluster).
Stage two: 9 households from each primary sampling unit were selected to create a cluster, thus the sample size of total survey clusters was 25488 households distributed on the governorates, 216 households in each district.
----> Sampling Stages:
In each district, the sample was selected in two stages:
Stage 1: based on 2010 listing and numbering frame 24 sample points were selected within each stratum through systematic sampling with probability proportional to size, in addition to the implicit breakdown urban and rural and geographic breakdown (sub-district, quarter, street, county, village and block).
Stage 2: Using households as secondary sampling units, 9 households were selected from each sample point using systematic equal probability sampling.
Sampling frames of each stages can be developed based on 2010 building listing and numbering without updating household lists. In some small districts, random selection processes of primary sampling may lead to select less than 24 units therefore a sampling unit is selected more than once , the selection may reach two cluster or more from the same enumeration unit when it is necessary.
Iraq Household Socio Economic Survey (IHSES) reached a total of 25488 households. Number of households refused to response was 305, response rate was 98.6%. The highest interview rates were in Ninevah and Muthanna (100%) while the lowest rates were in Sulaimaniya (92%).
The selection probability (Phij) of household (hij) in PSU (hi) of stratum (h) is given by:
Where (nhi) indicates the number of households in (PSU) and (Nh) indicates the number of households in stratum. The two symbols are mentioned in the right side of the formula and represent the probability of PSU selection and conditional probability for household selection within PSU.
The formula can be simplified as follows:
(Phij = 216/Nh)
This formula is given an equal probability to select 216 households as a sample in each district, it simplifies the process of results analysis where sample is auto-weighted to analyze results at district level whereas survey results analysis at governorate and national level requires the appropriate probability processes.
Survey instrument
----> Preparation:
The questionnaire of 2006 survey was adopted in designing the questionnaire of 2012 survey on which many revisions were made. Two rounds of pre-test were carried out. Revision were made based on the feedback of field work team, World Bank consultants and others, other revisions were made before final version was implemented in a pilot survey in September 2011.
After the pilot survey implemented, other revisions were made in based on the challenges and feedbacks emerged during the implementation to implement the final version in the actual survey.

Field staff was organized into teams that each consisted of 3 interviewers and a local supervisor . The survey used 68 teams were distributed by districts in each governorate.
----> Reference period:
The field work of the first wave started on 16/1/2012 and continued for 15 days distributed on 10 days for field work and 3 for office work. The 1 year reference period for the survey was broken down into (24) waves the work carried out during each wave continued for 15 days. Field staff was organized into teams that each consisted of 3 interviewers and a local supervisor. The survey used 68 teams were distributed by districts in each governorate.
----> Field visit schedule:
A time schedule was prepared to follow up recording the household expenditures and to ensure accurate completion of the four – part questionnaire. Five field visits were scheduled for each household. The schedule covering all tasks- from the first visit, handing over the daily expenditure diary to the household to recovering the diary on the final visit.
----> Training:
World Bank carried out a 6-day workshop for main trainees in Beirut at the end of July 2011. In the Central Statistical Organization a training course also carried out in September (10-15) attended by central supervision team and governorates coordinators whereas Kurdistan Region Statistics Office carried out a training course in September (12-15) in Erbil Statistics Directorate attended by statistics directors in KR governorates and survey cadre.
At the beginning of October 2011 a 7- day second workshop was organized by the WB in Beirut to set the survey timetables and train trainers. In 3/12/2012, training and preparing IHESE field staff were launched in 7 training centers in (Ninevah, Kirkuk, Anbar, Baghdad, Wasit, Babil, Basrah). In 20/12/2012 three training centers were opened in Erbil, Sulaimaniya and Duhouk where training courses were carried out for the 18 governorates field staff. The courses continued for 23 days of which 5 days were allocated for applied training in selected urban and rural areas of different social and economic levels.
----> Data Entry:
Survey administration in cooperation with the World Bank consultants prepared a new plan for data entry and assigned number of IT staff in CSO to follow-up data entry process in the governorates. Data daily collected by the interviewer were entered by using a new and advanced method, namely Excel program screens. It also provided each interviewer with a lap top to enter data collected from the households to be sent to the data management center via internet.
Data processing
----> Raw Data:
Data Editing and Processing:
To ensure accuracy and consistency, the data were edited at the following stages:
- Interviewer: Checks all answers on the household questionnaire, confirming that they are clear and correct.
- Local Supervisor: Checks to make sure that questions has been correctly completed.
- Statistical analysis: After exporting data files from excel to SPSS, the Statistical Analysis Unit uses program commands to identify irregular or non-logical values in addition to auditing some variables.
- World Bank consultants in coordination with the CSO data management team: the World Bank technical consultants use additional programs in SPSS and STAT to examine and correct remaining inconsistencies within the data files. The software detects errors by analyzing questionnaire items according to the expected parameter for each variable.
----> Harmonized Data:
- The SPSS package is used to harmonize the Iraq Household Socio Economic Survey (IHSES) 2007 with Iraq Household Socio Economic Survey (IHSES) 2012.
- The harmonization process starts with raw data files received from the Statistical Office.
- A program is generated for each dataset to create harmonized variables.
- Data is saved on the household and individual level, in SPSS and then converted to STATA, to be disseminated.
