Suburb vs suburb
Pick two suburbs, the same record answers for both. Reports filed, crashes counted, schools, parks, bus stops and the places the register remembers, in one table with the caveats still attached.
Counts are what the public record holds, a report tally measures the stream, not the suburb’s virtue.

Questions, answered briefly
Diamond Harbour counts 1,610 people (2023) to Lyttelton's 3,220; Diamond Harbour covers 3.02 km², Lyttelton 6.27 km²; the record holds 1,752 reports for Diamond Harbour and 5,530 for Lyttelton.
Lyttelton, 75 on the heritage register to the other’s 9.
The same public record for both, council reports, the crash register, the heritage schedule, Stats NZ’s counts. The stream counts reports, not virtue; the caveats are each suburb’s own.
Questions, answered briefly
Two suburbs' public records side by side: reports filed, crashes counted, schools, parks, bus stops, heritage places, population and density. Every number is the same dataset the suburb pages use.
Not necessarily. The record counts what people chose to report, population, awareness and reporting habits all move the number. Read it as the suburb’s report stream, not a complaint league table.
The same public sources as everywhere else on the site: council reports via Snap Send Solve, NZTA’s Crash Analysis System, the council’s parks and facilities layers, Metro’s stop data, the Heritage New Zealand register, and census figures via Wikipedia’s suburb summaries.
