Correlation of ecological footprint (2008) and the human development index (2012)

The Human Development Index is calculated using three components: education,
life expectancy at birth and wealth. It is expressed as a value between 0 and 1, from
less to most developed countries.

The Ecological Footprint measures how much land and water area a population
requires to produce the resources it consumes and to absorb its waste. The world
biocapacity is the global productive area available on Earth (it decreases as
population grows).
