chch.live two suburbs, side by side

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.

Or try one: the city vs Riccarton · Linwood vs Phillipstown · Akaroa vs Lyttelton

Questions, answered briefly

What does this page compare?

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.

Does a suburb with more reports have more problems?

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.

Where does the data come from?

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.
