Recorded criminal incidents for the whole suburb — raw counts (the approximate per-1,000-resident rate uses the 2021 Census population, which may lag actual growth), so larger suburbs naturally record more, and small-area counts fluctuate year to year. The latest year shown is the last complete calendar year. Context, not a verdict; we publish no suburb rankings.
