Different things drive population change at different scales. We form a view at each level, and each level constrains the one below it.
| Sub-area (SA3) | Area character | Capacity used by 2046 |
|---|---|---|
| Frankston | 91.0% | |
| Mornington Peninsula | 94.8% | |
| Mornington Peninsula total | 92.7% |
Capacity used is the share of an area's assessed dwelling capacity that the forecast draws down by 2046. Assessed capacity is post-census capacity across 213 tracked residential development sites, so it counts what those sites can hold, not every theoretical dwelling a planning control would permit.
