Over the years, the world has unequivocally become more equal with positive long-term trends regarding a large variety of critical metrics such as average income, rates of educational attainment, and internet access, especially in less developed countries.
Respected scholars, academic institutions, and international organizations have proven that long-term improvements in living standards and well-being have occurred through progress over the last two centuries.
The Human Progress Index (HPI) measures well-being. It considers different aspects of human development on an easily understood scale from 0 to 1, where higher values reflect greater well-being than lower values. To calculate such an index, the United Nations Human Development Index is taken into account, which is based on three components (life expectancy, schooling, and income) and indicators such as political freedom, adequate nutrition, infant mortality, environmental quality, and internet access are added. Through this measure, the HPI has shown improvements in global well-being in the past three decades, highlighting the significant development in overall equality since 1990.
