Currently, over 219,000 firms in 159 economies have been surveyed following the Enterprise Surveys Global Methodology. For details about the economies surveyed, sample characteristics, and year of data collection, see the Sample Description document. In addition, older surveys which were not conducted using a standard methodology are hosted on the Enterprise Surveys website. Emerging economies are the primary focus and a few developed economies have been surveyed for comparative purposes. Survey data from 2006 onwards is available in the Enterprise Surveys Data Portal. Data from older surveys (with the exception of BEEPS data) may be available from the Archive which is located inside the Data Portal.

Questionnaires, sampling notes, and other survey documentation are available on the Methodology page. Information about the implementation of specific surveys can be found in the Enterprise Surveys Data Portal along with the raw datasets. Each survey is accompanied by an implementation report detailing some aspects of fieldwork.

Yes, the list is compiled on an ongoing basis but may not be comprehensive.  If you have research that is not in the list, please send an email to enterprisesurveys@worldbank.org and it will be added to the list.

The website is updated approximately every month with new survey data. Research products such as Enterprise Notes and Working Papers are posted periodically.

The World Bank's Enterprise Surveys began in 2002 and were conducted by different units within the World Bank (previous names include "PICS" or "Investment Climate Surveys"). Since 2005-06, most data collection efforts have been centralized within the Enterprise Analysis Unit. Centralization of the survey implementation has resulted in a unified set of core survey questions and a consistent application of survey methodology across economies.

The Questionnaire Codebook is a good place to start. The Excel tables contain most of the core questions that are currently asked of firms. Another way to get a sense of the overall survey themes and types of questions asked is to explore the different topic pages on the website (upper right-hand corner of the homepage). Users with knowledge of Stata or other statistical software packages are encouraged to become registered users of the Data Portal.

The manufacturing and services sectors are the primary business sectors of interest. This corresponds to firms classified with ISIC codes 15-37, 45, 50-52, 55, 60-64, and 72 (ISIC Rev.3.1). Formal (registered) companies with 5 or more employees are targeted for interview. Services firms include construction, retail, wholesale, hotels, restaurants, transport, storage, communications, and IT. Firms with 100% government/state ownership are not eligible for interview. The Methodology page contains more detailed information.

Enterprise Surveys implemented in Eastern Europe and Central Asian economies are also known as Business Environment and Enterprise Performance Surveys (BEEPS) and are jointly conducted by the World Bank and the European Bank for Reconstruction and Development.

The list of economies surveyed (and the years of data collection) can be found in this Excel document.

Unfortunately, the Enterprise Analysis team can not provide access to, or support for, many of the surveys conducted prior to 2005. We are unable to support many of the older datasets in their raw form. There is however a standardized dataset spanning 2002-2005 on the Data Portal that contains a core set of matched variables.  Please inquire at enterprisesurveys@worldbank.org to see if a specific survey is available.

Panel data is survey data for the same firm over multiple years. For example, a business in Brazil was interviewed in an Enterprise Survey conducted in 2003 and it was also interviewed in the Enterprise Survey conducted in 2009. Panel datasets can be downloaded in the Enterprise Surveys Data Portal. Panel datasets consist of the multiple waves of survey data where the firm-level records are "stacked on top of each other" across the multiple years. Panel datasets exist for most ECA economies, some African economies, and a few South and East Asian economies. The Sample Description Excel document lists which economies have panel datasets.

Universe figures (or estimates) are available in the Implemenation Reports in the Enterprise Surveys Data Portal along with each raw dataset. Usually the Universe figures are obtained from an economy's national statistics agency (directly or from the agency's website). When Universe figures are unavailable from the government, the Enterprise Surveys team usually estimates the number of eligible firms for survey participation (especially when undertaking block enumeration to build a sample frame).

We are unable to support many of the older datasets in their raw form. There is however a standardized dataset spanning 2002-2005 on the Data Portal that contains China 2003 and other economies with a core set of matched variables. If you wish to use the original raw dataset we suggest you contact the Task Manager for the China 2003 survey directly.

In each survey project, the sample design aims to include the main cities/regions of economic activity. The actual number of cities depends on the size of the economy. Major cities include the city itself as well as the surrounding areas.

Registered users can download the data and corresponding survey questionnaire for each economy in the Enterprise Surveys Data Portal. Both registration and downloading data are free.

Indicators are created using weighted (weight=w_median) data. For each economy for a particular survey question, the indicator is created using the weighted average (or the weighted percentage of firms that responded 'Yes') across firms. Some website indicators are based on the combination of two survey questions. The website also allows users to view indicators by strata variables (firm size, geographic location within a economy) and also by a few ex-post variables (exporter status, foreign ownership, gender of top manager). Some indicators are based on questions only asked of manufacturing firms. The Methodology page has a listing of all website indicators. Note that when indicators are presented on the website for a broad geographic region or income group (e.g. Africa region or "Upper Middle Income"), a simple average is computed using the relevant, available economy-level indicators.

The Methodology page has the most recent versions of the global questionnaires. The Enterprise Survey covers a wide range of business environment topics including general business characteristics, infrastructure and services, sales and supplies, access to finance, degree of competition, land, crime, business-government relations, investment climate constraints, labor, and productivity. There are manufacturing-specific questions as well as a few retail-specific questions. In collaboration with economists in the regional departments of the World Bank, every Enterprise Survey is customized to include economy-specific questions (or region-specific questions). The questions are mostly objective questions aimed at measuring the quality of the business environment and the experience of firms. Less than 10% of the questions are subjective, that is asking the respondent for his/her opinion. The question answers are mostly the following types: yes/no, a percentage or monetary amount, days required to obtain a service, number of times a particular event has occurred, or a 5-point Likert scale.

economy data includes all questions that were asked in a survey but may lack comparability across economies and years. Standardized data is economy data that has been matched to a standard set of questions. This format allows cross-economy comparisons and analysis but sacrifices those economy-specific survey questions which cannot be matched. The standardization process requires that certain compromises are made in order to match some of the variables. Thus, we encourage our users to pay close attention to the actual wording of the survey questions and to use the raw economy datasets for their analysis.

For most economies, monetary values are reported in local currency units. When downloading raw data from the portal, data users are encouraged to download the accompanying survey questionnaires and documentation which provide the exact wording of each survey question. No adjustments are made to inflate/deflate the reported monetary values for costs and sales figures.

Unfortunately, some questions are not included in our questionnaire because it is already quite lengthy in size. The current set of questions takes about an hour to conduct, and adding new questions may increase both item and unit non-response. If you have suggestions for improving existing questions or adding new questions to the survey instrument, please send us an email with your suggestions and we will consider them for potential inclusion in future surveys.

The indicator '% of Women in Senior Positions" has been replaced by the indicator "% of Female Permanent Full-Time Non-Production Workers". We have also added another new indicator: "% of Firms with Female Top Manager" (question B.7a).

The weights in the more recent Enterprise Surveys data are probability weights. Using these weights allows inference on the population of non-agricultural private firms (that meet the Enterprise Surveys eligibility criteria) in a economy. In Stata, a survey design should be declared before performing any analysis. Specifically, this command should be used: svyset idstd [pweight=wt], strata(strata) singleunit(scaled). The survey commands using ‘svy’ should be used in calculating any statistics to be interpreted for the population of non-agricultural private firms. For statistics related to specific types of firms, analysts should use the subpopulation option in Stata.

We do not provide such correspondence tables but they can be made by matching the questionnaires available on the Portal by hand. There are however  standardized datasets spanning 2002-2005 and 2005-Present on the Data Portal that contain a core set of matched variables.

Most of the new surveys conducted after 2006 contain ISIC Rev. 3.1 industry code, which is a 4 digit code used to describe a firm's business activity (question D.1a2). Question D.1a1 contains the text description of the business' main product. Please see the raw data available on the Enterprise Surveys Data Portal for details.

When the sampling methodology calls for stratification by geographic location (within an economy), the region labels can be found in the dataset itself or the questionnaire instrument will list the geographic locations along with the coding scheme. The implementation report will describe how many interviews were conducted in the various geographic locations.
