This is the second nationwide Iraq Household Socio-Economic Survey (IHSES-II) which was conducted in 2012. The first round Iraq Household Socio-Economic Survey (IHSES-I) was conducted in 2006-07.
The Iraq Household Socio-Economic Survey conducted in 2006-07 (IHSES 2007), was Iraq’s first nationwide income and expenditure survey since 1988. Based on the model of the Living Standards Measurement Surveys, it covered more than 18,000 households, collected detailed data on all aspects of household income and expenditure and generated information on a wide variety of socio-economic indicators. It also formed the basis for updating the Consumer Price Index (CPI), from an outdated index based in 1990 to a revised index with the base year of 2007. Detailed analysis of poverty, its incidence, characteristics, determinants and consequences, was undertaken using this comprehensive survey. Under the overall guidance of the Poverty Reduction Strategy High Committee (PRSHC) and a technical sub-committee, a poverty line was defined and adopted by the Council of Ministers.
Six years later, in 2012, the second round of the IHSES surveys was completed. Learning from past and international experience on survey design, implementation and sampling, IHSES 2012 also incorporated additional modules on areas of evolving interest. It is the most comprehensive socio-economic survey as yet undertaken in Iraq.
1. To provide data to help measure and analyze poverty and monitor the implementation of the national strategy to alleviate poverty (issued in 2009) and update it with a new strategy.
2. Provide an integrated system of data to assess the social and economic situation of families and develop indicators related to human development.
3. Provide data meeting the requirements and needs of the national accounts.
4. Provide detailed indicators of consumer spending and the impact of various changes in it to serve the production, consumption, export and import decision-making.
5. Provide detailed indicators of the incomes of individuals and families by source.
6. Provide the data required for creating a new index record of consumer prices beyond 2012.

The IHSES-II intends to provide estimators of comparable quality for each of Iraq’s 118 gadahs (districts). This implies that the sample should be explicitly stratified by gadah, with a similar sample size allocated to each gadah, regardless of its size. A sample size of 216 households per gadah is proposed, equivalent to a total sample of 25,488 households for the country.
Within each gadah, the sample will be selected in two stages, as follows:
- First, using Census Enumeration Areas (EAs) as Primary Sampling Units (PSUs), select 24 EAs with Probability Proportional to Size (PPS), using the number of households as a Measure of Size (MoS), and with implicit stratification by urban/rural and the subsequent geographical codes (nahya, mahala, village, mukataa and census block).
- Second, using households as secondary Sampling Units (SSUs), select a cluster of 9 households by systematic, equal probability sampling (SEPS) in each of the selected EAs.
The sample frames for both stages can be developed from the 2010 Census enumeration, with no updating of the household lists.
In some of the smallest gadahs, the standard PPS procedure may result in the selection of fewer than 24 EAs, with some of the larger EAs selected more than once. In those cases, two or more clusters will be taken in the EA, as needed.
2,832 EAs were selected in total. 33 of them had less than the 9 households nominally required in the second stage and were merged ex-post with neighboring EAs.
Multiple weights have been provided. The variable "Weight" is the inverse of the selection probability, adjusted to match qadha-wise population". The variable "weight_s7_adult" is the weight for the analysis of adult anthropometrics. The variable "weight_s21" is the weight for the analysis of time-use data. And the variable "weight_s24" is the weight for the analysis of food consumption by recall.
Dates of Data Collection
Data Collection Mode
The data were collected using paper questionnaires with concurrent data entry in the field using Computer Assisted Field Entry (CAFE)
Data Collection Notes
The IHSES-II fieldworkers were organized into teams of three interviewers, headed by a supervisor. Each team was responsible for two gadahs (48 clusters) throughout the full 12-month period of data collection.
The team's work plan required visiting four clusters per month - two from each gadah. The month was divided into two waves. In Wave 1 (days 1 to 14), the team visits two clusters from one of the gadahs, and in Wave 2 (days 15 to 29), the two clusters from the other gadah.
In each wave, the team moved between clusters (but not between gadahs) on a daily basis, visiting one of the clusters on odd-numbered days, and the other cluster on even-numbered days.
Each interviewer was responsible for three households, and visited each of them every other day five times, with the following task schedule:
- In the first visit, the interviewer completed sections 1 to 3 and 24, deliver the food consumption diaries and explain their use.
- In the second visit, s/he transferred the data from the first day of diary-keeping to Section 12, and complete sections 4 to 8.
- In the third visit, s/he transferred the data from the second and third day of diary-keeping to Section 12, and complete sections 9 to 11.
- On the fourth visit, s/he transferred the data from the fourth and fifth day of diary-keeping to Section 12, and complete sections 13 to 16.
- On the fifth visit, s/he completed sections 17 to 23.
After the last scheduled visit, the interviewer conducted as many additional check-up visits as needed, to correct any doubts or inconsistencies in the data that might have been detected by the IHSES data entry program in any of the previous visits.
Each interviewer used a dedicated laptop computer to enter the data from his three households on a daily basis, meaning that the correction of doubts and inconsistencies wouldn't need to be postponed till the final days of the wave in many cases. In other words, error correction was also a complement of the data-collection tasks scheduled for the second to fifth visits.
The survey questionnaire has four parts:
Part 1 - Socio Economic
Part 2 - Expenditure
Part 3 - Income and other Data
Part 4 - Household Diary
