Nigeria: life expectancy is 15 years below a GDP-based estimate
195 countries compared in 2024. GDP per person here: $8,000, adjusted for prices. The fitted line at that GDP gives 70.1 years; the observation is 54.6 years. This is a model estimate, not an average of a matched group.

GDP alone does not describe differences between countries. The highlighted country lies far from a simple fitted line.
Dots are countries in one year; the line is the model. GDP uses a logarithmic scale.

OLS across 195 countries: indicator against log GDP per capita at PPP. Large residuals selected while exploring three relationships.

A question for this picture
Does the deviation persist with a different model and country sample?
