Why Choose This Factor

GNP (Gross National Product) or Affluence

Income (GDP per capita, PPP $)

X-Axis (Horizontal)

This is the best available measure of a country's wealth and economic status. Movement to the right means a country is getting richer.

QOL (Quality of Life)

Life expectancy (years)

Y-Axis (Vertical)

This is a primary measure of human welfare, health, and quality of life. Movement up means people are living longer.

Population/Scale

Population (Total)

Bubble Size

The size of the bubble represents the total number of people affected by the data. This shows the scale of the environmental impact.

Fertility Rate

Children per woman (Total fertility rate)

Optional: Y-Axis swap

You can substitute this for Life Expectancy to see the direct relationship between income and TFR.
