How to read this ranking
Pune leads the normalized comparison at 12.97
tagged reports per 10,000 civic reports. Mumbai leads raw volume
with 52 reports. The two leaders can differ because normalization
controls for each city's overall civic-news footprint.

Primary and companion measures
Noise Pollution reporting signal by city
The primary rank uses tagged reports per 10,000 civic reports. Raw rank,
recent change, and active years show whether a result depends on city size, timing, or a narrow burst.
47 tagged reports appeared within

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 noise_pollution; 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.
