The HPI is a measure of human well-being and environmental impact. It is calculated using three factors: life expectancy, subjective well-being, and ecological footprint.

The HPI was developed by the New Economics Foundation (NEF) in 2006.

The HPI is calculated using three factors: life expectancy, subjective well-being, and ecological footprint.

Costa Rica has the highest HPI score in 2023, followed by Finland, Denmark, and Iceland.

The Central African Republic has the lowest HPI score in 2023, followed by Chad, Niger, and South Sudan.

The relationship between HPI and GDP per capita is complex and varies across countries. Some countries with high GDP per capita also have high HPI scores, while others have low HPI scores. This suggests that economic growth is not the only factor that determines human well-being and environmental impact.

The HPI has been criticized for being too subjective and relying on self-reported data, for not taking into account the distribution of well-being within a country, and for not being a good measure of environmental impact.

The HPI is a useful measure of human well-being and environmental impact because it is simple and easy to understand, it is a comprehensive measure that takes into account multiple factors, and it can be used to compare the performance of different countries.

Countries can improve their HPI score by investing in education and healthcare, by reducing their ecological footprint, and by promoting sustainable economic growth.

The goal of the HPI is to promote sustainable development, to raise awareness of the importance of human well-being and environmental impact, and to encourage countries to adopt policies that improve the well-being of their citizens and reduce their environmental impact.
