Inches, not just percentages: India’s GDP is rising, but a four-inch gap with China tells another story

The Indian economic discourse has recently found itself trapped in a familiar, exhausting loop. With every release of GDP figures, a predictable tug-of-war ensues. On one side, we see celebration of 'fastest-growing major economy' status. On the other, multiple commentators question deflator methodologies, base year revisions, and the gap with observable ground realities.

Our collective obsession with a single headline number - GDP growth to the first decimal point - may be the problem. One is reminded of Goodhart's Law: when a measure becomes a target, it ceases to be a good measure. GDP is a vital barometer. But it's a blunt, singular instrument. It may tell you how fast the wheels are turning. But it doesn't always tell you if the vehicle is reaching its destination. To truly understand a nation's trajectory, one must adopt a more holistic view of development.

China's GDP figures have been a subject of intense global scepticism for years. Yet, on the ground, the debate over whether the growth was 5% or 6% feels secondary to the undeniable reality of the development that has taken place. Infrastructure is no longer about 'potential' but a finished, world-class reality. From futuristic airports to a bullet train network to preponderance of EVs, the scale is unmatched.


But development is never a straight line. China's real estate crisis is not just a headline but a visible landscape. Massive residential projects that once padded GDP figures now stand mothballed or abandoned - reminders that when a single metric (like GDP-contributing construction) becomes the sole target, the result can be a profound misallocation of capital.

But the most striking observation of anyone visiting China has nothing to do with infrastructure or innovation. It's a biological manifestation of holistic progress: teenagers. Walking through Shanghai or Hefei, one is struck by teenagers being significantly taller than their parents.

This anecdotal observation is confirmed from data from The Lancet that the average male 19-yr-old Chinese now stands at 5 ft 9 in. This represents a staggering gain of nearly 4 in (10 cm) over the height of the average 55-yr-old Chinese man. Chinese youth have now achieved height parity with their counterparts in the US and Britain.

This observation isn't an argument to replace GDP with a 'tape measure' as our primary economic tool. Rather, it serves as a powerful proxy for the totality of development. You can manufacture GDP by building 'ghost cities', but you cannot manufacture an extra 4 in of average height without improvement in standard of living. It requires the compounding effect of decades of rising household incomes, better nutrition and reliable healthcare.

This brings us back to the Indian context and our obsession with the '5% vs 7%' debate. While we argue over whether our GDP growth is being measured correctly, we should be widening our lens to look at more holistic barometers of well-being.

Our progress is undeniable. By World Bank's measure, India's extreme poverty rate has roughly halved in past decade from over 20% to about 12%. Household electrification, bank deposit penetration and rural sanitation coverage are all near-universal access.

Yet, gaps remain. An average male 19-yr-old Indian's height has remained relatively stagnant at around 5 ft 5½ in. The 'height gap' between a Chinese and an Indian teenager is now nearly 4 in. India's childhood stunting rate - children under 5 who are too short for their age, a marker of chronic malnutrition - is still over 35%, nearly 7x China's under 5%.

The lesson is that GDP is merely the fuel, development is the vehicle. Real progress lives in the quiet indicators. Are children better nourished than their parents? Do they stay longer in school and learn more? Is the middle class thickening or thinning? Is the next generation taller, healthier and more capable?

If 20 yrs from now, the average Indian teenager stands a head taller than his grandfather, no one will be debating the GDP methodology. Until then, let's treat the number as a compass, without mistaking the map for the territory.
