Why does gdp per capita matter when comparing two countries economic performance?
It’s just a way of accounting for differences in populations. You couldn’t really compare the GDP of, say, China (over 1 billion) with the UK (60 million) just by comparing the raw numbers. China’s GDP is only twice as much as the UK’s, but its population is about 20 times more. Just looking at the actual numbers wouldn’t give you any meaningful information. So you divide by the population to compare the economic performance of both.
