These rates are not uniform across the country, and understanding their geographic patterning is essential for targeted policy. The National Family Health Survey (NFHS) provides large, nationally representative data well suited to mapping where caesarean delivery is unusually common or uncommon. This study uses NFHS data and spatial analysis to identify geographic clusters of caesarean-section rates across India. https://arunmitra.com/research/tb-notification-gap-india/ Sat, 01 Nov 2025 00:00:00 +0000 https://arunmitra.com/research/tb-notification-gap-india/ Background India carries the world’s largest tuberculosis burden, and a central challenge for the National TB Elimination Programme is the gap between the TB cases that occur and the cases that are actually notified. National coverage figures hide enormous local variation: some districts notify nearly everyone they should, while others miss a large share of their true burden. This project asks where India misses tuberculosis — at a resolution fine enough to be actionable — and why. https://arunmitra.com/research/stroke-reperfusion-access/ Sun, 01 Jun 2025 00:00:00 +0000 https://arunmitra.com/research/stroke-reperfusion-access/ Background Acute ischaemic stroke is a time-critical emergency in which reperfusion therapy, intravenous thrombolysis (IVT) and endovascular thrombectomy (EVT), must be delivered within a narrow therapeutic window to salvage brain tissue. In a country as large and geographically heterogeneous as India, the practical benefit of these treatments depends not only on whether capable centres exist but on whether patients can physically reach them in time. This study asks a simple but consequential question: what share of India’s population actually lives within a one-hour drive of a stroke centre equipped to deliver IVT or EVT, and how does that access vary across regions?
