The survey was conducted in Iraq between March and October 2011 as part of the Iraq Enterprise Survey, an initiative of the World Bank. Data from 756 establishments was analyzed.
The objective of the survey is to obtain feedback from enterprises on the state of the private sector as well as to help in building a panel of enterprise data that will make it possible to track changes in the business environment over time, thus allowing, for example, impact assessments of reforms. Through interviews with firms in the manufacturing and services sectors, the survey assesses the constraints to private sector growth and creates statistically significant business environment indicators that are comparable across countries.
The standard Enterprise Survey topics include firm characteristics, gender participation, access to finance, annual sales, costs of inputs/labor, workforce composition, bribery, licensing, infrastructure, trade, crime, competition, capacity utilization, land and permits, taxation, informality, business-government relations, innovation and technology, and performance measures. Over 90% of the questions objectively ascertain characteristics of a country’s business environment. The remaining questions assess the survey respondents’ opinions on what are the obstacles to firm growth and performance. The mode of data collection is face-to-face interviews.
Kind of data
Sample survey data [ssd]
First version of the dataset.
Regions covered are selected based on the number of establishments, contribution to employment, and value added. In most cases these regions are metropolitan areas and reflect the largest centers of economic activity in a country.
Unit of analysis
The primary sampling unit of the study is the establishment. An establishment is a physical location where business is carried out and where industrial operations take place or services are provided. A firm may be composed of one or more establishments. For example, a brewery may have several bottling plants and several establishments for distribution. For the purposes of this survey an establishment must make its own financial decisions and have its own financial statements separate from those of the firm. An establishment must also have its own management and control over its payroll.
The whole population, or universe of the study, is the non-agricultural economy. It comprises: all manufacturing sectors (group D), construction sector (group F), services sector (groups G and H), transportation, storage, and communications sector (group I), and the IT sector (ISIC 72 in group K). Note that this definition excludes the following sectors: financial intermediation (group J), real estate and renting activities (group K, except sub-sector 72, IT), and all public or utilities-sectors. Unregistered (informal) firms, firms with less than 5 employees, or 100% state-owned enterprises are not eligible for the survey.

The sample for Iraq was selected using stratified random sampling. Three levels of stratification were used in this country: business sector, establishment size, and governorate.
Business sector stratification was defined by creating six levels: the universe was stratified into four manufacturing sub-sectors (food, non-metallic mineral products, and chemicals/rubber products) and an "other manufacturing" category, retail/wholesale, and an "other services" category.
Size stratification was defined by three levels following the standardized definition for the Enterprise Surveys: small (5 to 19 employees), medium (20 to 99 employees), and large (more than 99 employees). For stratification purposes, the number of employees was defined on the basis of reported permanent full-time workers.
Regional stratification was defined by 10 sub-national locations (governorates) in Iraq: Ninevah, Kirkuk, Baghdad, Babil, Kerbala, Al-Najaf, Thi-Qar, Basra, Suleimaniyah, and Arbil.
Iraq's Central Organization for Statistics (COSIT) with the cooperation of Kurdistan Regional Statistical Office (KRSO) provided the World Bank with a sampling frame, generated in 2009 during the initial discussions regarding Enterprise Surveys. However despite the target sample design of 1,000 firms (which was known to be extremely ambitious at the outset of the survey project), the list from COSIT contained 959 firms. Transportation, storage, and communications sectors (group I) along with the IT sector were missing in this sampling frame.
Given the missing sectors and below-target total of firms in the sample frame, the implementing contractor solicited and obtained lists of registered companies from local (governorate-level) chambers of commerce. The implementing contractor provided the World Bank with Excel sheets from seven governorates. 106 firms in sectors group I and ISIC 72 were randomly selected and appended to the list of 959 firms from COSIT. Thus a total of 1,065 firms constituted the sample frame provided to the implementing contractor.
The overall survey response rate was 92%.
The number of firm contacts per realized interview was 1.37. This number is the result of two factors: explicit refusals to participate in the survey, as reflected by the rate of rejection (which includes rejections of the screener and the main survey) and the quality of the sample frame, as represented by the presence of ineligible units. The number of rejections per contact was .06.
Item non-response was addressed by two strategies:
a- For sensitive questions that may generate negative reactions from the respondent, such as corruption or tax evasion, enumerators were instructed to collect the refusal to respond as a different option from don’t know (-7).
b- Establishments with incomplete information were re-contacted in order to complete this information, whenever necessary.
Survey non-response was addressed by maximizing efforts to contact establishments that were initially selected for interview. Attempts were made to contact the establishment for interview at different times/days of the week before a replacement establishment (with similar strata characteristics) was suggested for interview. Survey non-response did occur but substitutions were made in order to potentially achieve strata-specific goals.
For some units it was impossible to determine eligibility because the contact was not successfully completed. Consequently, different assumptions as to their eligibility result in different universe cells' adjustments and in different sampling weights. Three sets of assumptions were considered:
a- Strict assumption: eligible establishments are only those for which it was possible to directly determine eligibility.
b- Median assumption: eligible establishments are those for which it was possible to directly determine eligibility and those that rejected the screener questionnaire or an answering machine or fax was the only response. Median weights are used for computing indicators on the www.enterprisesurveys.org website.
c- Weak assumption: in addition to the establishments included in points a and b, all establishments for which it was not possible to finalize a contact are assumed eligible. This includes establishments with dead or out of service phone lines, establishments that never answered the phone, and establishments with incorrect addresses for which it was impossible to find a new address. Note that under the weak assumption only observed non-eligible units are excluded from universe projections.

The current survey instruments are available:
- Manufacturing Questionnaire,
- Services Questionnaire,
- Screener Questionnaire.
The standard Enterprise Survey topics include firm characteristics, gender participation, access to finance, annual sales, costs of inputs/labor, workforce composition, bribery, licensing, infrastructure, trade, crime, competition, capacity utilization, land and permits, taxation, informality, business-government relations, innovation and technology, and performance measures. Over 90% of the questions objectively ascertain characteristics of a country’s business environment. The remaining questions assess the survey respondents’ opinions on what are the obstacles to firm growth and performance.
English questionnaires (Manufacturing and Services Questionnaires) were provided to the implementing contractor for translation to Arabic and Kurdish. The translated questionnaires were back-translated into English by a third party so that instances of sub-optimal translation could be identified and corrected.

Data entry and quality controls are implemented by the contractor and data is delivered to the World Bank in batches (typically 10%, 50% and 100%). These data deliveries are checked for logical consistency, out of range values, skip patterns, and duplicate entries. Problems are flagged by the World Bank and corrected by the implementing contractor through data checks, callbacks, and revisiting establishments.
Confidentiality of the survey respondents and the sensitive information they provide is necessary to ensure the greatest degree of survey participation, integrity and confidence in the quality of the data. Surveys are usually carried out in cooperation with business organizations and government agencies promoting job creation and economic growth, but confidentiality is never compromised.
