Is Diep River Safe? 77/100 Safety Score (2026)

Diep River scores 77 out of 100 on StreetSignal’s safety index - lower reported crime. Its annualised crime count is 3,792, spread across a station population of 32,445 residents. The crime trend is declining.

For a suburb with a R2.5M median property valuation in the Southern Suburbs, these are numbers worth understanding in detail.

A note on methodology: StreetSignal’s safety index is a relative measure comparing reported crime across Cape Town’s 744 suburbs; it is not an absolute safety guarantee. The index is a composite of two sub-dimensions: harm-per-resident (rate) and absolute harm volume. A score of 77/100 reflects the geometric mean of both. Diep River’s rate sub-index is 65/100 and its volume sub-index is 91/100. Full methodology is documented on the StreetSignal methodology page.

Why does Diep River score 77 out of 100?

SAPS publishes crime statistics at police precinct level, not suburb level. The Dieprivier precinct serves approximately 32,445 residents and covers Diep River along with neighbouring suburbs including Bergvliet, Meadowridge, and Elfindale. StreetSignal’s crosswalk assigns 99.2% of Diep River to this precinct.

The rate sub-index (65/100) reflects moderate per-capita crime pressure - not the lowest in the metro, but well below the city-wide median. The volume sub-index (91/100) confirms that absolute harm is low. The geometric mean of 65 and 91 produces the composite of 77.

Critically, the trend is Down. Weighted harm-days fell from 1,082 in Q3 2024 to 948 in Q3 2025. When both the score and the trend point in the same direction, the signal is stronger.

How does Diep River compare to its neighbours?

Suburb	Safety index	Annualised crimes	Trend	Median valuation
Diep River	77/100	3,792	Down	R2.5M
Plumstead	77/100	3,792	Down	R2.4M

Meadowridge	77/100	3,792	Down	R2.3M

Diep River, Plumstead, Meadowridge, and Constantia all share the Dieprivier precinct and therefore the same safety index. Bergvliet falls under the Kirstenhof precinct (score 24/100, 2,796 annualised crimes, Stable trend) - a materially different safety profile despite its geographic proximity. The differentiator among the Dieprivier suburbs is price: Diep River delivers the same safety profile as Constantia at one-third of the property cost.

Elfindale is served by the Steenberg precinct (score 83/100), offering a different but also favourable safety profile.

Is Diep River safe for families?

The data points in the same direction. A safety index of 77/100 with a declining crime trend, zero murders in the most recent quarter, residential burglary more than halved year-on-year, a nearest clinic 100 metres away, and household conditions that rank among the strongest in the metro.

The trade-off is school choice within the suburb itself - four schools, none secondary. But the Southern Suburbs corridor compensates. Transport is car-dependent (87% private vehicle), which is typical for this part of Cape Town.
