Geographic Coverage notes
There is several notes to consider:
- Cross-boundary Small Area Layers (SALs) were corrected for 24 specific SAL codes that were misallocated between adjacent precincts (e.g., Chalumna, Duncan Village, Fort Brown, Kenton-on-Sea, Kinkelbos, Khubusi Drift, Thomas River, New Brighton, Swartkops, Kuruman, Kleinsee, Modder River, Heidedal, Maydon Wharf, Mayville-KZN, Vorsterhoop, Vaal Marina, Hekpoort, OR Tambo, Protea Glen, Boschkop, Rietgat, Kaapmuiden, Cumberland).
Geographic Unit
The lowest level of geographic aggregation for the ppcd-2011-v1 data file is the SAPS police precinct (police station service area), which is built from Census 2011 Small Area Layer (SAL) units mapped to police precincts. While for the ppcd-metro-2011-v1 data file it is the police precinct, with the 8 metropolitan municipalities collapsed into single metro-level observations. Note that non-metro stations retain precinct-level granularity.
