Suburb Population Notes

Suburbs with fewer than 1,000 Census persons are flagged with small_suburb_warning. Synthetic populations for these suburbs may show higher variance due to source data sparsity. Suburbs with original Census populations below 100 have their pool floored to 100 records to ensure usability.

Roadmap

v1.1; Person-Family-Dwelling Linking (Planned)

Hierarchical household structure linking persons to families and families to dwellings. Will substantially improve dwelling-level analyses and enable cross-dataset queries.

v1.2; Additional Variables (Subject to Demand)

Health-related variables and additional industry/occupation breakdowns based on customer feedback.

v2.0; Census 2026 Recalibration (2027/28)

Full recalibration to Census 2026 data when published by ABS. Will update all conditional distributions, variable definitions, and marginal targets.

Update Cadence

Quarterly: WPI and CPI indices refreshed as new ABS releases become available. Income and housing cost distributions updated accordingly.

Annually: Full marginal recalculation incorporating latest ERP population estimates. Pool sizes updated for all suburbs.

As needed: Validation rule additions, bug fixes, and documentation updates.
