HDI – Human Development Index
The Human Development Index (HDI) is a composite statistic used to measure and compare the overall well-being of people in different countries, combining indicators of health (life expectancy), education (mean and expected years of schooling), and standard of living (gross national income per capita). It is compiled and published annually by the Human Development Report Office within the United Nations Development Programme (UNDP), under the editorial oversight of the United Nations General Assembly to ensure its independence and credibility. The HDI draws upon the latest data from a wide range of reputable public international organizations—such as the World Health Organization, UNESCO, and the World Bank—and is frequently used by national and regional analysts to inform policy debates and track progress over time.

GPI – Global Peace Index
The Global Peace Index is produced by the Institute for Economics & Peace, a global think tank that measures peace and its economic benefits. It uses 23 indicators in three main areas to score a country’s “negative peace” (the absence of violence or fear of violence). The first area, ongoing domestic and international conflict, has six measures that look at a country’s involvement in internal or external fights and how long they last. The second area, societal safety and security, uses eleven measures to check crime rates, terrorist activity, violent protests, political stability, relations with neighbors, and how many people are displaced or become refugees. The third area, militarization, has six measures to track military spending as a share of GDP, the number of armed service members per person, and contributions to UN peacekeeping. This single score lets us compare how peaceful different countries are.
The index uses a ranking scale from 1 (most peaceful) to 5 (least peaceful), and these values are aggregated into a single composite score to compare the peacefulness of different countries.

Henley Passport Index
The Henley Passport Index uses information from the International Air Transport Association (IATA) to show which passports offer the most travel freedom around the world, based on how many places citizens can visit without needing a visa.
The index reviews 199 passports and checks how many of 227 destinations (including countries, territories, and regions) each passport holder can access without applying for a visa in advance. https://www.iata.org/en/services/compliance/timatic/

PS: Not every place issues passports, so there are more destinations than passports in the ranking.
