Most firms in most economies are small. Yet most economic statistics describe large firms better than small ones. The World Bank’s Enterprise Surveys are a partial exception: they ask firms about finance, infrastructure, regulation, workforce and other operating conditions, and make methods and country-level materials available for comparison. Understanding what they capture, and what falls outside, is essential before drawing conclusions about the businesses that dominate employment.
What the surveys capture
Enterprise Surveys use a standard questionnaire across many countries, which makes comparisons possible. They cover firm size, sector, ownership, access to finance, electricity, informal competition, corruption, and the time managers spend on regulation. For each country they publish a sample of establishments and documentation of how it was drawn. The strength of the approach is its consistency: the same questions are asked in the same way, so differences between countries reflect differences in conditions rather than differences in the survey.
Where the smallest firms disappear
The surveys typically sample registered establishments above a minimum size, often five employees. That threshold excludes the micro-enterprises and own-account workers who make up a large share of employment in many economies. The result is a blind spot exactly where policy often matters most. A survey of firms with five or more employees cannot describe the street vendor, the home-based seamstress, or the one-person repair shop, and those are precisely the businesses that face the sharpest barriers to finance and formality.
The informal economy problem
A related gap is informality. Many small firms operate wholly or partly outside the formal system, and they are hard to reach with a survey built on business registers. Informality shapes everything: access to credit, exposure to regulation, ability to enforce contracts. A picture of the formal sector alone will systematically understate the constraints facing the smallest and most vulnerable businesses.
Even with those limits, the findings are useful. Across many countries, small firms report tighter access to finance than large ones, more frequent power outages, and a heavier relative burden from regulation. These patterns recur, which suggests they reflect structural features of how economies treat smaller enterprises rather than quirks of particular countries. They give reformers a starting point for asking why credit, infrastructure and rules fall unevenly.
Self-reporting and perception
Survey answers are perceptions. A manager’s assessment of corruption or regulatory burden is real in its effects, it shapes decisions, but it remains a perception rather than an objective measurement. This is a strength and a weakness. It is a strength because perceptions drive behaviour; it is a weakness because they can be influenced by recent experience, media coverage or the way a question is worded. Reading the results alongside administrative data helps separate perception from reality.
Why firm size changes the analysis
The constraints facing a firm with five employees and one with five hundred are not the same problem at different scales; they are different problems. A large firm can absorb a compliance cost that would consume a small firm’s entire margin. A small firm may lack the collateral for a loan that a large firm secures easily. Aggregating them into an average hides the mechanism. Disaggregating by size is what makes the findings actionable.
Better data on micro-enterprises would require different methods: household surveys that capture self-employment, administrative records from tax and social-security systems, and mobile or phone-based sampling. Some countries are moving in this direction. Until more do, any claim about “the business environment” should specify whose business environment it means.
How to use these surveys
Use them to compare conditions across countries and over time, and to identify which constraints firms rank highest. Then ask who is missing from the sample, and whether the missing firms face the same constraints more severely. The survey is a map of the formal, registered economy, valuable, but not the whole territory.
Why definitions differ
What counts as a “small” firm varies by country and by purpose. Some definitions use employee numbers, others turnover or balance-sheet size, and the thresholds differ widely. A business that is small by the standards of a large economy may be mid-sized elsewhere. This makes cross-country comparison of “small firms” treacherous: an apparent difference in conditions may reflect a difference in definition rather than a real one. Analysts should check the threshold used before drawing conclusions, and treat any aggregate labelled “SMEs” with caution.
A country-level average from an Enterprise Survey is a summary of many different firms, and summaries can conceal as much as they reveal. Before citing a figure, it helps to check the sample size, the sectors covered and the year of collection, because conditions change and a small sample can swing widely. It also helps to compare the survey with other sources, tax records, business registries, credit data, to see whether the patterns hold. Where several independent sources agree, confidence is warranted; where they diverge, the divergence is itself the finding, pointing to a gap between what firms report and what administrative systems record.
