Some indicators and datasets do not include data on high-income countries. This typically occurs because high-income countries are not World Bank borrowers and thus are not obligated to report figures on topics such as debt and aid. High-income countries do not report the following data:

• External debt: the World Bank Debtor Reporting System reports debt from borrowing countries only, excluding high-income countries;
  
• Aid data: high-income countries do not report aid data because they are not aid recipients;
  
• Poverty data: the scope of poverty series focuses on developing countries (low and middle-income) only;
  
• Country Policy and Institutional Assessment: the CPIA database covers countries with IDA eligibility, which is restricted to low-income countries;
  
• Enterprise Surveys;
  
• Private Participation in Infrastructure
