Data & the future of sustainable development

On 11 March, 2011, the Great East Japan earthquake and tsunami struck with terrifying force. As towering waves swallowed cities and nuclear reactors faltered, another quieter force surged forward, data. Japan's decades of investment in seismic monitoring, hydrological mapping, and statistical modeling enabled a rapid response that saved thousands of lives. Data didn't stop the disaster. But it ensured the nation didn't collapse under it.

On this National Statistics Day, we pause to honour Prof. Prasanta Chandra Mahalanobis, the mind who gave India not just a formula but a framework. A pioneer who believed that a country's plans must be rooted not in ideology, but in evidence. Who saw in statistics not an abstraction, but an instrument of nation-building. His legacy is etched not only in the Mahalanobis Distance, but in India's planning history, in institutions like the Indian Statistical Institute, and in the very idea that governance must have an empirical soul. In today's India, that soul must become our compass.

The world has pledged itself to 17 Sustainable Development Goals, ambitious, interconnected, and urgent. Yet, nearly 40% of SDG indicators remain statistically blind in many nations. Progress becomes a mirage when we cannot measure what matters. The World Bank's 2021 Development Report calls it the “data paradox”: a world flooded with data but starved of insights that are timely, trusted, and transformative.
