Which Indian cities show the strongest heat wave reporting signal?

A comparison of 45 Indian cities covered by Prism Geo. 13 pass the evidence gates and are ranked by exact heat_wave-tagged news reports per 10,000 civic reports. This measures the prominence of a topic in coverage—not real-world incidence, prevalence, or safety.

Where the heat wave reporting signal is concentrated

Every highlighted polygon is the 2021 administrative district containing a ranked city's coordinate. Color shows the city's reporting-signal rank band—not a measured district-wide rate, prevalence, or severity assessment.

How to read this ranking

Bhubaneswar leads the normalized comparison at 10.92 tagged reports per 10,000 civic reports. New Delhi leads raw volume with 98 reports. The two leaders can differ because normalization controls for each city's overall civic-news footprint.

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 heat_wave; 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.
