Examples
-
GDP Per Capita: This measure divides a country’s gross domestic product by its population, providing an average economic output per person. It’s like slicing a cake into equal pieces rather than just looking at the whole cake!
Formula:
\[
\text{GDP Per Capita} = \frac{\text{GDP}}{\text{Population}}
\]
-
Income Per Capita: This reflects the earnings of an average individual within a population. If you only compare total earnings, it’s like claiming the richest person has the best pizza because they buy the most slices!
Formula:
\[
\text{Income Per Capita} = \frac{\text{Total Income}}{\text{Population}}
\]
