Enterprise Survey [en/oth]
An Enterprise Survey is a firm-level survey of a representative sample of an economy's private sector. Firm-level surveys have been conducted since 1998 by different units within the World Bank. Since 2005-06, most data collection efforts have been centralized within the Enterprise Analysis Unit. The Enterprise Surveys are conducted every three to four years across all geographic regions and cover small, medium, and large companies. Data are used to create indicators that benchmark the quality of the business and investment climate across countries.
The Enterprise Survey initiative includes two types of surveys: Enterprise Surveys and Indicator Surveys. This study is an Indicator Survey. An Indicator Survey is similar to an Enterprise Survey; it is implemented for smaller economies where the sampling strategies inherent in an Enterprise Survey are often not applicable due to the limited universe of firms. The survey instrument is limited to just those questions which form the basis of the global indicators as presented on the Enterprise Surveys website www.enterprisesurveys.org.
This research is an Indicator Survey conducted in Congo from Sept. 15, 2008, to Feb. 13, 2009 , as part of the Enterprise Survey initiative. An Indicator Survey is similar to an Enterprise Survey; it is implemented for smaller economies where the sampling strategies inherent in an Enterprise Survey are often not applicable due to the limited universe of firms.
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.
Questionnaire topics include firm characteristics, gender participation, access to finance, annual sales, costs of inputs/labor, workforce composition, bribery, licensing, infrastructure, trade, crime, competition, land and permits, taxation, business-government relations, performance measures, AIDS and sickness.
The mode of data collection is face-to-face interviews.
Sample survey data [ssd]
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.
Coverage
National
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.
The whole population, or the universe, covered in the Enterprise Surveys is the non-agricultural economy. It comprises: all manufacturing sectors according to the ISIC Revision 3.1 group classification (group D), construction sector (group F), services sector (groups G and H), and transport, storage, and communications sector (group I). Note that this population definition excludes the following sectors: financial intermediation (group J), real estate and renting activities (group K, except sub-sector 72, IT, which was added to the population under study), and all public or utilities sectors.

Sampling
The sample for registered establishments in Congo was selected using stratified random sampling. Three levels of stratification were used in the Congo sample: firm sector, firm size, and geographic region.
Industry stratification was designed as follows: the universe was stratified into one manufacturing industry and one services industry (retail). The initial sample design had a target of 75 interviews each in the services and manufacturing categories, though this sample design was later adjusted to reflect the low prevalence of establishments in Congo.
Size stratification was defined following the standardized definition used for the Indicator 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 in terms of the geographic regions with the largest commercial presence in the country: Brazzaville and Pointe-Noire.
It was not possible to obtain a usable sample frame for Congo-Brazzaville, and so a blocks enumeration methodology was used: Detailed maps of Brazzaville and Pointe-Noire were obtained (i.e., aerial mappings were projected to a usable scale). They served as the basis of a multi-stage approach. First, each city was divided into "blocks", and then the blocks were classified into strata defined by the predominant spatial use. The classifications used for the blocks included industrial, commercial, residential, and commercial/residential (mixed) coding. The accuracy of the classification was tested using 29 pilot blocks. When that test proved to be successful, 200 more blocks were selected and 170 of those were enumerated (building by building, floor by floor). Each separate unit was identified and classified. Further details, such as employee numbers, activity, name, and phone number, were collected for business establishments. Universe totals were projected from this enumeration of 199 total blocks. The establishments enumerated were then used as the frame for the selection of a sample with the aim of obtaining interviews at 150 establishments with five or more employees.
The quality of the frame was assessed at the onset of the project and was not immune from the typical problems found in establishment surveys: positive rates of non-eligibility, repetition, non-existent units, etc. Given the impact that non-eligible units included in the sample universe may have on the results, adjustments may be needed when computing the appropriate weights for individual observations. The percentage of confirmed non-eligible units as a proportion of the total number of sampled establishments contacted for the survey was 22.74% (63 out of 277 establishments for the sample). Overall, 37 establishments were interviewed in manufacturing sector and 114 in services sector.
Complete information regarding the sampling methodology, sample frame, weights, response rates, and implementation can be found in "Description of Congo, Rep. Implementation 2009" in "Technical Documents" folder.
One set of weights for each cell was computed. The set of estimates calculated proportions using the raw sample count for each cell.
Survey instrument
The current survey instruments are available:
- Services and Manufacturing 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.

Private contractors conduct the Enterprise Surveys on behalf of the World Bank. Due to sensitive survey questions addressing business-government relations and corruption-related topics, private contractors are preferred over any government agency or an organization/institution associated with government, and are hired by the World Bank to collect the data.
The surveys were implemented following a two-stage procedure. In the first stage, a screener questionnaire was applied over the phone to determine eligibility and to make appointments; in the second stage, a face-to-face interview took place with the Manager/Owner/Director of each establishment. Sometimes the survey respondent called company accountants and human resource managers into the interview to answer questions in the sales and labor sections of the survey.
All Enterprise Surveys are conducted in the local languages.
Data processing
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.
Data Access
| Is signing of a confidentiality declaration required? | Confidentiality declaration text |
|---|---|
| yes | 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. |
