Trend columns show the January to March quarter for each year from 2022 to 2026 (like-for-like quarters). Source: SAPS quarterly crime statistics. SAPS section totals and police-action categories (drug crime, driving under the influence, illegal firearms) are excluded: totals double-count their components, and police-action figures track police effort rather than residential victimisation. Precinct assignment uses StreetSignal's own station-catchment construction, which can differ from official precinct boundaries; see themethodology.
Schools in Blackheath
Quintile mix: N/A: 1, Q5: 1 (quintile 1 serves the lowest-income communities, quintile 5 the highest).
- NORTHCLIFF HIGH SCHOOL (secondary school, 2025 matric 98.1% of 268)
- NORTHSIDE COLLEGE (secondary school)
What this matric figure is. National Senior Certificate results from the Department of Basic Education's 2025 School Performance Report, covering the one school here that presented candidates, so it describes that school rather than the suburb. Each school is weighted by its candidate numbers. It is the share of those who wrote the exams and passed — learners who left school before Grade 12 are not counted in it, so it does not show how many children here finish school.
