Presenting analysis of international datasets offers additional complexities over single country analysis. Tables and graphs that display anything other than simple distributions for a range of countries can quickly get very busy and difficult to read. It is often useful to look to publications produced by international organisations such as the OECD, the World Bank or the UN who regularly have to summarise complex information on a large number of countries in a visual way.

For example, the results from the PISA study convey both the overall score for a country but also show whether it is significantly different from all the other countries presented. Similarly, the UN agencies such as the UN Statistics Division, UNESCO Institute of Statistics, the World Health Organisation, the International Labour Organisation and the Food and Agriculture Organisation of the United Nations all provide examples of how to present data comparisons across countries.
