The grey marker on each bar is the median across the 164 South Australia areas we publish a score for (state median overall: 63/100). It is context, not a pass mark.

How this score is calculated
Each published figure for the Happy Valley SA2 is mapped onto 0–100 by fixed thresholds, then weighted. Inputs with no data here are dropped and the rest rescaled - never scored as zero. Every threshold and weight →
