The National Family Health Survey (NFHS) is a cornerstone of India's public health system, yet its vast datasets are often locked in formats that are inaccessible for timely local-level decision-making. To address this critical gap, the Insight360TN platform was developed as a web-based tool to transform complex NFHS statistics for Tamil Nadu into interactive and actionable insights. Built entirely with client-side technologies, the platform integrates optimized NFHS-4 (2015–16) and NFHS-5 (2019–21) data to power a suite of analytical tools, including dynamic choropleth maps, district performance rankings, and correlation analyses. A key innovation is the integration of Google's Gemini 1.5 Pro AI, which generates natural language summaries to make statistical findings understandable to non-technical users. The result is a high-performance, cost-effective platform that successfully democratizes access to vital health data, demonstrating a powerful model for bridging the gap between data availability and evidence-based policymaking in Tamil Nadu.
