Definition: The Corruption Perception Index (CPI) is a globally recognized measure that assesses the perceived level of public sector corruption in countries around the world. It provides valuable insights into the prevalence and impact of corruption, helping to guide policy-making, international cooperation, and anti-corruption efforts.

Historical View

The CPI was first introduced by Transparency International (TI) in 1995 as a means to raise awareness about corruption and promote transparency and accountability. Since then, it has become one of the most widely used indicators to evaluate corruption levels worldwide. The index is based on a combination of data from various sources, including expert assessments and surveys, and it ranks countries on a scale from 0 to 100, with higher scores indicating lower levels of corruption.

Over the years, the CPI has played a significant role in shaping global anti-corruption initiatives and policies. It has increased public awareness, prompted governments to take action, and fostered international cooperation in the fight against corruption.

Practical Examples

The CPI serves as a powerful tool to understand the real-world implications of corruption. Here are some practical examples of how the CPI is used:

  1. Policy Guidance: The CPI informs policy decisions by highlighting areas where corruption is more prevalent. Governments can use this information to implement targeted reforms and strengthen their anti-corruption strategies.
  2. Comparative Analysis: The CPI enables comparisons between countries, allowing policymakers, researchers, and civil society to identify patterns, best practices, and areas for improvement in tackling corruption.
  3. Investment Decisions: Investors and businesses often consider the corruption levels in a country before making investment decisions. The CPI helps assess the integrity of business environments and guides investment strategies.
  4. International Cooperation: The CPI encourages cooperation among countries and international organizations in combating corruption. It serves as a common reference point for joint efforts and promotes knowledge sharing.
  5. Advocacy and Awareness: Civil society organizations, activists, and journalists use the CPI to raise awareness about corruption, advocate for accountability, and hold governments and institutions accountable.
  6. Evaluation of Anti-Corruption Efforts: The CPI provides a benchmark for evaluating the effectiveness of anti-corruption measures over time. Countries can monitor their progress and adjust strategies based on changes in their CPI scores.
  7. Identification of Vulnerabilities: The CPI helps identify sectors and institutions that are particularly susceptible to corruption. This knowledge enables targeted interventions and the implementation of preventive measures.
  8. International Rankings: The CPI generates rankings that attract global attention. Countries strive to improve their scores and climb the ranks, enhancing their reputation and credibility on the international stage.
  9. Resource Allocation: The CPI guides the allocation of resources for anti-corruption efforts. Countries can prioritize areas with higher corruption risks and allocate funds accordingly.
  10. Public Engagement: The CPI fosters public discourse and engagement on corruption-related issues, empowering citizens to demand transparency, accountability, and good governance.

“The Corruption Perception Index plays a vital role in guiding policy-making and shaping anti-corruption efforts worldwide.”


Statistics derived from the CPI provide valuable insights into the global state of corruption:

  • Average Global Score: The average global CPI score in 2020 was 43 out of 100, indicating a perceived corruption problem in most countries.
  • Top-Ranked Countries: New Zealand and Denmark consistently rank among the top countries with the lowest perceived levels of corruption, with scores above 85.
  • Challenges in Regions: Sub-Saharan Africa and Eastern Europe face significant corruption challenges, with average CPI scores below 45.
  • Impact on Development: Corruption hinders economic development and affects the delivery of public services. It is estimated that corruption costs the global economy more than $1 trillion annually.
  • Regional Variations: CPI scores vary significantly across regions, reflecting the diverse anti-corruption landscapes and governance practices around the world.
  • Global Corruption Hotspots: Several countries consistently rank low on the CPI, indicating high levels of corruption. These include Somalia, South Sudan, Syria, and North Korea.
  • Correlation with Other Indices: The CPI is often correlated with other indicators, such as the Rule of Law Index, suggesting that corruption undermines the rule of law and weakens governance.
  • Improvement and Regression: Some countries have made significant progress in reducing corruption over time, while others have experienced regression due to political instability or inadequate anti-corruption measures.
  • Perceptions and Reality: The CPI reflects perceptions of corruption, which may not always align with the actual extent of corruption in a country. It serves as a starting point for further analysis and investigation.
  • Long-Term Trends: Analyzing CPI scores over the years helps identify long-term trends, providing insights into the effectiveness of anti-corruption measures and policy interventions.

While the CPI measures perceived corruption levels, numerous incidents highlight the real-world consequences of corruption:

  1. Embezzlement and Misappropriation: High-level officials misusing public funds for personal gain, diverting resources from essential services and development projects.
  2. Bribery and Extortion: Public officials demanding bribes or engaging in extortion to provide services or favorable treatment, undermining fairness and equity.
  3. State Capture: Corruption infiltrating state institutions, enabling private interests to exert undue influence on policy-making, legislation, and public procurement.
  4. Political Corruption: Corruption influencing political processes, including election rigging, illegal campaign financing, and nepotism in appointments.
  5. Grand Corruption: Large-scale corruption involving high-ranking officials, resulting in significant financial losses and erosion of public trust.
  6. Corruption in Public Procurement: Manipulation of procurement processes to award contracts to preferred bidders, often at inflated prices, compromising fairness and competition.
  7. Money Laundering: Illicit funds generated through corruption being laundered and integrated into the global financial system, perpetuating criminal activities.
  8. Corruption in the Judiciary: Corruption within the judicial system, such as bribes to influence court decisions, eroding trust in the rule of law and undermining justice.
  9. Corruption in Healthcare: Diversion of resources, kickbacks, and fraudulent practices in the healthcare sector, compromising the delivery of essential services and endangering lives.
  10. Corruption in Education: Bribery and fraud in education systems, such as the sale of degrees or unfair access to educational opportunities, undermining meritocracy and equal access.

“Real incidents of corruption underscore the need for collective action to combat this pervasive problem.”
