Results show a significant variation among these countries, but some major trends.
We also estimated a global GPI/capita over the 1950–2003 period. Global GPI/capita peaked in 1978, about the
same time that global Ecological Footprint exceeded global Biocapacity. Life Satisfaction in almost all countries
has also not improved significantly since 1975. Globally, GPI/capita does not increase beyond a GDP/capita of
around $7000/capita. If we distributed income more equitably around the planet, the current world GDP
($67 trillion/yr) could support 9.6 billion people at $7000/capita. While GPI is not the perfect economic welfare
indicator, it is a far better approximation than GDP. Development policies need to shift to better account for real
welfare and not merely GDP growth
