What is the open budget survey? Definition and scope

The Open Budget Survey is the International Budget Partnership’s recurring independent assessment of national budget transparency, oversight and public participation. The IBP states that the OBS is the primary global tool for comparing how governments disclose and open up budget information to the public, and it produces both country narratives and a cross-country dataset for reuse Open Budget Survey 2023. For the OBS project overview see the main OBS page Open Budget Survey.

In its most recent full cycle the OBS assessed 125 countries that together represent roughly 95 percent of the world population and budgets totaling more than US$33.5 trillion, and IBP makes both narrative reports and downloadable country-level data available to users Open Budget Survey data and country profiles.

The survey produces numeric scores and a set of component measures so that countries can be compared on transparency, oversight and public participation rather than on single anecdotes.

Country profiles and the full dataset are published by IBP so users can download the raw data and check the underlying entries for each country Open Budget Survey data and country profiles.

Who produces the OBS

The International Budget Partnership, a research and advocacy organization, produces the Open Budget Survey and related technical materials as a public resource.

IBP explains the objectives, scope and country coverage in the OBS report and on the project pages, where users can find country profiles and the downloadable dataset Open Budget Survey 2023.

What OBS measures at a national level

At the national level the OBS measures whether key budget documents are published, whether oversight institutions have access to information, and whether there are formal opportunities for public participation.

Those measures are operationalized through a standardized questionnaire and converted into index and component scores that allow cross-country comparison OBS methodology and codebook.

Scope of the most recent full cycle

The 2023 cycle covered 125 countries and is the primary cross-country OBS dataset available in 2026, which makes it the main reference point for most comparative work using IBP data Open Budget Survey 2023. The 2023 findings are summarized on the OBS 2023 page Open Budget Survey 2023.

The available country pages include narrative summaries, tables of component scores and links to methodological notes so users can follow how each score was derived Open Budget Survey data and country profiles.

Who uses the open budget survey and for what purposes

Policymakers, researchers and civil society groups commonly use the OBS to compare budget transparency across countries and to track change over time.

Observers use the survey to identify missing budget documents, weaknesses in oversight institutions, and opportunities to strengthen public participation in budget processes Open Budget Survey 2023.

For example, an advocacy group may use OBS component scores to show which documents a government routinely fails to publish, while a researcher might merge OBS scores with governance indicators for comparative analysis Open Budget Survey data and country profiles.

Users should be cautious when drawing policy conclusions from OBS alone because the survey mainly measures the publication of documents and formal rules rather than actual implementation at national or subnational levels OBS methodology and codebook.

How the open budget survey methodology works

The OBS uses a standardized questionnaire known as the OBS codebook. The codebook specifies which primary budget documents to check and how to record answers from document review and expert input OBS methodology and codebook.

IBP applies the questionnaire to primary budget documents and to responses from local experts in each country; those inputs feed into the scoring process.

After data collection IBP converts coded answers into the Open Budget Index on a 0 to 100 scale and into component scores for transparency, oversight and public participation, which are intended for comparative analysis rather than as absolute measures of implementation quality OBS methodology and codebook.

The methodology materials and codebook are published so that others can reproduce scoring steps and check how specific items were coded in the dataset.

The OBS codebook and standardized questionnaire

The codebook lists the documents and the precise questions asked about each document, including whether a document is published, what it contains and when it is made public.

The structured questionnaire helps ensure that the same items are checked in every country, which supports reproducible cross-country comparisons OBS methodology and codebook.

Primary documents and expert inputs

IBP relies on reviewers to consult primary national documents such as executive budget proposals, enacted budgets and audit reports and to record findings in the questionnaire.

Local expert responses supplement the document review and provide context for coding decisions, and IBP documents these procedures in the technical resources Open Budget Survey data and country profiles.

Scoring: Open Budget Index and component scores

Coded answers are aggregated into the Open Budget Index, which sits on a 0 to 100 scale, and into component scores that separate transparency, oversight and public participation.

Those numeric outputs are intended to show relative performance and to help users spot gaps in published information or oversight arrangements rather than to prove that a government has implemented reforms in practice OBS methodology and codebook.

Interpreting OBS scores: what they mean and what they do not

An OBS index score provides a comparative signal about how openly a country publishes budget information relative to others in the dataset.

Users should read the overall index alongside component scores, because the transparency component, the oversight component and the participation component capture different aspects of budget openness OBS methodology and codebook.

It is a common misinterpretation to treat the publication of documents as proof that those documents are used effectively. The OBS measures availability and formal rules more than real world implementation, so publication alone should not be equated with effective oversight or participation OBS methodology and codebook.

Similarly, a national OB index should not be assumed to reflect subnational practice; local budgets and implementation can differ significantly from national-level disclosure practices How open are country budgets.

Step-by-step: using OBS data for a country-level review

Start on the IBP data page and the country profile for the country you are reviewing. These pages provide narrative context, the downloaded tables and links to codebook references Open Budget Survey data and country profiles. You can also check related posts on my news page News.

Download the country CSV or the full dataset and open the fields that record the coded questionnaire responses and the component calculations.

Key fields to check include the items that record whether specific documents were found, the coded answers for oversight and participation items, and the calculated component scores used to produce the overall Open Budget Index Open Budget Survey data and country profiles.

When reproducing a score, save the dataset version and note the retrieval date. Also record which IBP country page and which national documents you consulted so others can follow your steps OBS methodology and codebook.

Practical example: reading an OBS country profile

Open an IBP country page and start with the narrative summary, which explains the main drivers of that country’s scores and highlights missing documents or strong oversight institutions.

When verifying a coding decision check the national executive’s budget publication, the enacted budget, and any audit reports cited in the IBP notes. If a document is absent from the national portal, note the version and the date searched.

Always cite both the IBP country page and the national primary documents you used when reporting findings so readers can check your sources.

Limitations and complementary tools to consider

The OBS is focused on the availability of published documents and on formal rules that enable oversight and participation; it does not directly measure how well those rules are implemented in practice OBS methodology and codebook.

To broaden an assessment, users often compare OBS results with the IMF Fiscal Transparency Code and with national audit reports to capture implementation and technical fiscal details Fiscal Transparency Code.

Combining OBS with other instruments can help fill gaps such as subnational transparency and day-to-day implementation that the OBS codebook does not capture in depth.

Common mistakes and pitfalls when using OBS data

A common mistake is to equate publication of a document with effective implementation. The presence of a published file does not prove that oversight bodies used it or that citizens could meaningfully engage OBS methodology and codebook.

Another pitfall is relying on the overall index without reviewing component-level nuance. The oversight and participation components can tell a different story than the transparency component alone, so inspect each component score.

Finally, do not use OBS as the only input for policy judgments. Corroborate findings with national audit reports, fiscal codes and other country-level evidence before drawing strong conclusions Open Budget Survey data and country profiles.

How researchers and advocates adapt OBS for analysis

Researchers often merge OBS country scores with governance and macroeconomic indicators to test correlations or to build comparative datasets for academic work Open Budget Survey 2023.

Advocates use country profiles and component breakdowns to write policy briefs that highlight missing documents and to prioritize transparency reforms at the national level Open Budget Survey data and country profiles.

Because IBP publishes the methodology and codebook, researchers can reproduce scoring decisions and, where appropriate, contest or clarify specific coding entries by documenting which primary sources were consulted OBS methodology and codebook.

Practical checklist: verifying an OBS claim for publication

Minimum checks before citing an OBS score: confirm the IBP country page and dataset version, download the coded responses, and locate the national primary documents referenced by IBP Open Budget Survey data and country profiles. You can also find related resources on the Michael Carbonara homepage Home.

Recommended attribution phrasing includes statements such as “according to the IBP Open Budget Survey 2023” while avoiding causal claims that a higher score proves better implementation Open Budget Survey 2023.

Document the dataset retrieval date and the exact IBP URLs you used so readers can reproduce your steps and check the same files.

Case scenarios: three ways practitioners use OBS results

Scenario A: An advocacy group uses OBS component scores to show a government does not publish a key budget document and advocates for routine publication as a transparency reform Open Budget Survey 2023.

Scenario B: A researcher merges OBS transparency and oversight scores with governance indicators to test whether budget openness correlates with public finance outcomes Open Budget Survey data and country profiles.

Scenario C: A journalist summarizes an IBP country profile, then confirms the presence or absence of documents using national budget portals and audit reports before publishing a report for a public audience Fiscal Transparency Code.

Summary and practical next steps for readers

Key takeaways: the OBS is a standardized, reproducible global assessment of budget transparency, oversight and public participation produced by IBP and published with country pages and datasets Open Budget Survey 2023.

Main limits: OBS primarily measures publication and formal rules rather than implementation or subnational practice, so combine OBS findings with audit reports and IMF instruments for a fuller view OBS methodology and codebook.

Three recommended next steps: consult the IBP country pages for the country you are researching, download the coded dataset and check the national primary documents, and record the dataset version and retrieval date when you cite scores Open Budget Survey data and country profiles.

Appendix: methodological notes for advanced users

IBP provides downloadable datasets and the OBS codebook so advanced users can reproduce scores and inspect individual questionnaire items OBS methodology and codebook.

Known caveats include reliance on published documents and the interpretive decisions required when a document is partially available or ambiguous; the codebook documents many of these choices.

Advanced tips: work with the original coded CSV, document any recoding you do, and reference both the dataset version and the codebook section used when publishing results Open Budget Survey data and country profiles.

Final note on responsible reporting

Use neutral attribution language such as “according to the IBP Open Budget Survey 2023” and avoid implying that an OBS score alone proves a policy outcome or implementation success Open Budget Survey 2023. See the author About page for context About.

Always cite the IBP country page and any national primary documents you use, and include the dataset version and retrieval date to support reproducibility and verification.
