Demand & supply signals
Population growth
Year-on-year change in resident population.
As of Jan 2025
3-year CAGR
Compound annual growth rate over the last 3 years.
As of Jan 2023
Supply pressure
Undersupplied means population growth is in the top quartile of SA2s nationally and dwelling approvals per capita are in the bottom quartile.
As of Jan 2025
Supply pipeline
Trailing-12-month dwelling approvals divided by the existing Census dwelling stock. Higher means more new homes coming relative to what's already there.
As of Jan 2025
Migration demand
1.0× is the state's fair share of net overseas migration by population. Above 1 means it's pulling more than its weight; below 1 means it's pulling less. State-grain — every SA2 in the same state shares this value.
As of Jan 2024
Approvals vs. completions
Trailing-four-quarter dwelling approvals minus completions for the state. Positive means more homes are being approved than finished — a pipeline buffer if delivery keeps pace, a backlog if it doesn't. State-grain — every SA2 in the same state shares this value.
As of Jan 2025
Demand pressure
Composite of state-level population growth and net overseas migration z-scores. Higher values = above-average demand pressure for the state. State-grain — every SA2 in the same state shares this value. Doesn't yet include payroll-jobs growth (separate ABS feed pending).
As of Jan 2024
Serviceability direction
State wage growth (ABS WPI) compared to the national change in housing lending rates (RBA F6 historical). Positive = wages outpacing rates (serviceability easing); negative = rates outpacing wages (tightening). State-grain — every SA2 in the same state shares this value.
Quarterly — most recent quarter both inputs have data for.
As of Jan 2025
Derived from ABS Estimated Resident Population, Census dwelling counts, dwelling approval counts, net overseas migration, the Wage Price Index, and RBA F6 housing lending rates. Published by the platform's metrics orchestrator on each upstream release.
Roadmap signals
Two more derived metrics are defined in the platform and waiting on upstream-data orchestration. Each will populate here once its source series is wired through.
Affordability trend
Coming soonRPPI year-on-year divided by WPI year-on-year. Above 1.0 means home prices are outpacing wages; below 1.0 means wages are catching up.
Awaiting: ABS RPPI (6432.0) + WPI (6345.0) GCCSA-grain orchestration.
Rent–price momentum spread
Coming soonCPI rents year-on-year minus RPPI year-on-year. Positive means rents are gaining on prices; negative means prices are running ahead of rents.
Awaiting: ABS CPI rents component + RPPI orchestration.
