Why might per-capita real economic growth be a more useful measurement than absolute real economic growth?

Absolute Real Economic Growth is the total increase in a country's goods and services output over time. It doesn't take into account population growth. It is calculated by subtracting the initial GDP from the final GDP.

Per-capita Real Economic Growth is the rate at which the total output of goods and services of a country is growing, on a per person basis. It's calculated by dividing the real economic growth by the total population. This results in the average production/creation of goods per person.

Per-capita Real Economic Growth is considered more useful than Absolute Real Economic Growth as it provides a more accurate picture of living standards in a country. It lets us know whether an economy is growing faster or slower than its population. If absolute growth is high but population growth is also high, the growth might not result in increased standards of living, as the increased output is spread out among a larger population. On the other hand, even a modest absolute growth can result in substantial increases in living standards if population growth is slow or negative. Thus, Per-capita Real Economic Growth can provide a more nuanced understanding of how much an average individual's income changes over time.
