Comparing countries - GDP per capita & HDI
In both economies and life, it’s challenging to determine the value of something without a point of comparison. For instance, we recognize a Maybach as expensive because we know most cars are significantly cheaper in comparison. Similarly, we label people as ‘rich,’ ‘educated,’ or other such tags based on relative comparisons. A couple of generations ago, holding a bachelor’s degree was considered a marker of high education. However, in my hometown today, even a PhD seems to carry little value.
Returning to the main point, we assess whether an economy is performing well or achieving high growth by comparing it to other economies. If all economies were growing at 10%, India's or China's growth rates wouldn’t seem particularly remarkable.
Out of curiosity, I created the table below, which compares the GDP per capita (both nominal and PPP-based) of several major economies as a percentage of India’s and China’s GDP per capita for the years 2005, 2010, 2019, and 2024. I avoided 2020 due to the COVID anomaly, and the data for 2024 is estimated (sourced from the IMF Economic Outlook, October 2024). You might need to open the image in a new tab for a clearer view of the data.
1) The resilience of the U.S. economy is remarkable. Between 2019 and 2024, the U.S. has widened its lead in terms of GDP per capita relative to China and India. This means that, on a per-person basis and in absolute terms, the U.S. economy grew faster than both. However, when viewed through the lens of purchasing power parity (PPP), the Chinese and Indian economies continue to catch up steadily. I assume much of this U.S. growth can be attributed to an exceptionally strong dollar and post-COVID inflation but correct me if I'm wrong. Given the massive size of the U.S. economy, even a modest 2.5% growth translates into substantial absolute gains. That being said, dark clouds loom in the form of divisive politics and erosion of key institutions which might accelerate based on the results of the upcoming elections.
2) The Chinese economy is facing a relative decline. From 2005 to 2015, China surged ahead, taking a significant lead over India—even during a period when the Indian economy itself was growing rapidly. However, from 2015 to 2024, China’s momentum slowed, and we now see the gap between the two economies starting to close, albeit gradually. This is happening despite India facing its own challenges during this era, including demonetization and the COVID-19 pandemic, as well as China’s near-zero population growth, which positively impacts its GDP per capita. We can expect the gap to close more quickly in the coming half-decades.
3) Russia has been a surprising case. After 2015, one might have expected Russia’s economy to perform worse, especially with sanctions. Yet, the decline relative to other economies has been as steady as that of the U.S., though from a much lower base. Interestingly, Russia’s economy has held up well post-Ukraine war, I assume likely due to increased oil trade and government stimulus to support its war effort.
4) Both the U.K. and Japan have experienced steady decline. These two economies have seen a consistent relative decline compared to both China and India, and this trend holds even when compared to the U.S. Remarkably, the U.K. is now poorer than Mississippi in terms of GDP per capita. However, it raises the question: is the average American truly living better than the average Briton or Japanese citizen? This points to the broader limitations of GDP as a measure of overall well-being.
To address the limitations of GDP as a measure of human capital and well-being, we turn to the Human Development Index (HDI) (data from UNDP). As we know, the HDI offers a broader perspective by incorporating factors like education, health, and standard of living. When comparing HDI scores, the U.S. ranks similarly to the U.K. and Japan and actually lags behind in certain areas like life expectancy. However, even the HDI has its shortcomings—it doesn’t account for income inequality, which can significantly skew perceptions of overall well-being. For a more comprehensive view, we would need to look at the inequality-adjusted Human Development Index (IHDI), which could be a topic worth exploring another day.
