Mahalanobis gave our data system global recognition and we must ask why we lost that credibility

In the summer of 1946, at the ‘nuclear’ session of the United Nations Statistical Commission (UNSC), a representative of a British colony made an impassioned plea for laying down globally accepted standards for conducting large-scale sample surveys. Prasanta Chandra Mahalanobis argued that household surveys would become invaluable data sources for many developing countries that were not fortunate enough to have the kind of rich administrative datasets that advanced economies boasted of.

Mahalanobis’s suggestion was accepted, and given his unique experience in conducting such surveys at the Indian Statistical Institute (ISI), he was asked to chair the first sub-committee of the UNSC on sampling. The global manual on sampling, which the world would follow for the next few decades, owed a large debt to Mahalanobis and his colleagues’ work at the ISI. ISI’s innovations—such as using a pilot survey to test a survey and the use of replicating samples to ascertain the magnitude of different kinds of errors in surveying—were adopted across the world.
