How Prism Geo built this ranking
Universe: 45 Indian cities with an existing Prism Geo city manifest; conservative legacy names such as Bangalore/Bengaluru are merged.
Window: complete calendar years 2021–2025. Partial 2026 data is excluded.
Signal: the exact source tag helicopter_crash; topic variants are not silently combined.
Score: tagged reports ÷ all civic reports × 10,000; raw volume is shown alongside it.
Coverage, action, and conclusion figures are classifier outputs. Multiple reports can concern one event, and absence of coverage is not absence of a problem.
Source: marketai.civic_geo_agg. This dataset supports comparison of reporting patterns only; it cannot establish actual case counts, risk, prevalence, or official performance.
