Two different machines

Urban notices and rural notices do not come from the same cause

Every notice is either an anomaly in the submitted form or a no mapping failure, where the elector could not be matched to the previous roll. Sorted left to right by how much of each seat's notice count comes from no mapping, the tall bars collect almost entirely at the no-mapping end.

Where the relationship breaks

A high ASDDO share does not mean a high notice rate

Each bubble is one seat, sized by electorate. Across all 224 seats the two measures correlate at r = 0.85. Remove the 28 Bengaluru seats and it collapses to r = 0.16.

District league table

34 district blocks, ranked

The spread bar shows the range between a district's lowest and highest seat, with the white tick at the district rate. A tight bar means the district acted uniformly. A wide bar means seats inside one district were treated very differently.
