What is the Prosperity Index?
The Legatum Prosperity Index™ is a framework that provides a unique insight into how prosperity – characterised by inclusive societies, open economies, and empowered people – is forming and changing across the world. It is an annual ranking of 167 countries, which together contain 99.4% of the world’s population. It uses 300 country-level indicators, grouped into 67 policy-focused elements across 12 pillars, to measure the current state of prosperity in these countries and how it has changed over the past decade.
What is the purpose of the Index?
The Prosperity Index has been purposefully designed to be a transformational tool, and our ambition is that leaders around the world use it to help set their agendas for growth and development, and also enable others to hold them to account.
Can I use the Prosperity Index findings for my own purposes, and how should I reference it?
How is the Prosperity Index built?
To cover both economic and social wellbeing, the Prosperity Index faces the challenge of finding a meaningful measure of success at a national level.
We endeavour to create an Index that is methodologically sound. Details of the steps involved to select the indicators, standardise and appropriately weight the data, and provide scores is available here. We have also published a full methodology report with further details, which is available for download here.
Why are some countries not in the Index?
For some countries in the world there is a lack of available credible data and we have covered over 99% of the world’s population in the Index. To maintain a high level of quality, we only include countries that have data available for at least 50% of our indicators. We are always looking to include new countries as more data becomes available, and in 2019 we added 18 additional countries.

Why do some datapoints have different years?
The Prosperity Index includes 300 indicators for each country, which are grouped into 67 elements and 12 pillars. The data for these indicators is obtained from internationally 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 the data we use may not have been updated at the source.
