Government Transparency Index 2026

Methodology

The ZeroGov Transparency Index is a composite score (0-100) aggregating data from internationally recognized sources. We evaluate five pillars of transparency, each weighted according to its impact on citizens' ability to hold government accountable.

Five Pillars of Transparency

1. Budget Transparency (25%)

Does the government publish comprehensive, timely budget documents? We evaluate pre-budget statements, executive budget proposals, enacted budgets, in-year reports, mid-year reviews, year-end reports, and audit reports. Data source: International Budget Partnership's Open Budget Survey.

2. Legal Framework (25%)

Does the country have strong FOI (Freedom of Information) laws, whistleblower protections, anti-corruption legislation, asset disclosure requirements for officials, and lobbying regulations? We assess both the existence and enforcement of these laws. Data sources: Global Right to Information Rating, UNCAC implementation reviews.

3. Institutional Oversight (20%)

Are there independent institutions that check government power? This includes supreme audit institutions, independent judiciary, anti-corruption agencies, ombudsman offices, and parliamentary oversight committees. We evaluate their independence, resources, and track record. Data sources: World Justice Project, V-Dem Institute.

4. Press Freedom (15%)

A free press is essential for transparency — it's the mechanism through which government information reaches citizens. We incorporate press freedom indices, journalist safety records, media ownership transparency, and legal protections for investigative journalism. Data source: Reporters Without Borders.

5. Digital Access (15%)

Is government information accessible online? We evaluate open data portals, e-government services, digital budget tools, online legislative tracking, and the availability of government data in machine-readable formats. Data sources: UN E-Government Survey, Open Data Barometer.

Key Trends in 2026

Digital Transparency is the Fastest-Growing Pillar

The digital access pillar has seen the largest improvement over the past five years. 62 countries now operate dedicated open data portals (up from 34 in 2020). Machine-readable budget data is increasingly standard. Estonia, South Korea, and the UK lead in e-government innovation, making government services and data accessible through digital-first approaches.

Budget Transparency Has Plateaued

After a decade of improvement, global budget transparency scores have stalled. The countries that were going to open their budgets have largely done so. The remaining low-scorers face structural challenges — weak institutions, authoritarian governance, or conflict — that prevent improvement without fundamental political change.

Press Freedom Is Declining

This is the most concerning trend. Press freedom scores have declined for the sixth consecutive year globally. Even established democracies are introducing legislation that can be used to restrict investigative journalism. The rise of "strategic lawsuits against public participation" (SLAPPs) is chilling investigative reporting in Europe and beyond.

Anti-Corruption Enforcement Gap

Many countries have strong anti-corruption laws on paper but weak enforcement. Our data shows that 43 countries have comprehensive anti-corruption legislation scoring above 80/100 for legal framework — but enforcement effectiveness drops below 40/100 in 29 of those countries. Laws without enforcement are performative.

How to Read Your Country's Score

• 80-100 (High): Strong transparency institutions and practices. Continuous improvement needed but fundamentals are solid.
• 60-79 (Medium-High): Good framework with implementation gaps. Key areas for improvement are typically enforcement and digital access.
• 40-59 (Medium): Basic transparency infrastructure exists but significant weaknesses. Often characterized by strong laws but weak institutions.
• 20-39 (Low): Limited transparency. FOI laws may exist but are poorly implemented. Budget information is incomplete or inaccessible.
• 0-19 (Very Low): Minimal to no government transparency. Typically authoritarian states or conflict zones with no functioning oversight institutions.
