We've included answers to some of the more frequently asked questions below. However, please feel free to contact us should you requirement more information about the Index.
What is the Prosperity Index?
The Legatum Prosperity Index™ offers a unique insight into how prosperity is forming and changing across the world. The Index is an annual ranking of 149 countries that covers 96% of the world’s population and 99% of global GDP. The Index analysed the countries across 9 sub-indices – Economy, Entrepreneurship & Opportunity, Governance, Education, Health, Safety & Security, Personal Freedom, Social Capital and Environment. It is unique in defining prosperity as a combination of wealth and wellbeing.
What is the purpose of the Index?
The Prosperity Index paints a broad picture of what nations need to flourish. It is the most comprehensive tool of its kind and is the definitive measure of global progress. This makes it a powerful tool for leaders and decision makers around the world, to use in policy creation and implementation.
How is the Prosperity Index built?
We endeavour to create an Index that is methodologically sound. To that end, we publish a full methodology document to provide the reader with all the information required to understand the Legatum Prosperity Index™ in a way that is transparent, useful, and informative. Please refer to our Methodology page for a full description.
How can I access the data?
Can I use Prosperity Index data for my own purposes?
Why do some datapoints have different years?
The Prosperity Index includes 104 variables for each country, which underlie its nine sub-indices. These variables are obtained from international recognised and reliable sources, such as the World Bank or the Gallup© World Poll. We always use the most recently-available data in order to paint an accurate picture of each country. In a few cases that data we use may not have been updated at the source.
Why are some countries not in the Index?
For some countries in the world there is a lack of available data. To maintain a high-level of quality, we only include countries that have at least 80% of our data available. If less than 80% of data is available for a given country, we will not include it in the Index. We are always looking to include new countries as more data become available, such as in 2012 when we added 32 new countries and this year when we added an additional seven.
The Index has a huge amount of information. How do I reference it in my work?
To reference the Index , or its ranks and scores, please use the year of the Index you are referencing followed by ‘Legatum Prosperity Index™’. For example, '2016 Legatum Prosperity Index™'. When referencing specific variables used in the Index, please refer to the primary source of the variables and include a note (e.g. a footnote) that the variables are taken from the Legatum Prosperity Index™.
