What the AHI measures. The Australian Household Index is a weekly composite measure of household financial conditions in Australia. It publishes three headline measures: the AHI Score — overall household financial stress, combining cost pressure, formal financial outcomes, and leading indicators of future conditions; the Cost Pressure Index — what Australian households are paying for essential goods and services relative to 2019 pre-pandemic baselines; and the Stress Cycle Gap — the distance between cost pressure and composite financial stress. A positive gap means households are absorbing cost pressure without yet cascading into formal financial failure.
Data sources. Every signal in the AHI architecture is sourced from primary Australian government and regulatory data. The platform draws exclusively from: the Australian Bureau of Statistics (CPI, Housing Expenditure Survey, Wage Price Index, Lending Indicators, Retail Trade, National Accounts); the Reserve Bank of Australia (Financial Stability data, credit and charge card statistics, business conditions surveys, monetary policy data); the Australian Energy Regulator (Default Market Offer pricing, energy hardship data); the Australian Prudential Regulation Authority (mortgage arrears, banking system stress indicators); and the Australian Financial Security Authority (personal insolvency statistics). The AHI does not use commercial surveys, bank-sponsored research, or any data source with a commercial interest in the findings. No licensed data is used anywhere in the model.
Architecture. The AHI uses a three-tier architecture. Cost Pressure measures what households are paying across eight essential categories — housing, groceries, transport, fuel, insurance, health, energy, and telecommunications. Scores are calibrated against historical stress thresholds derived from Australian administrative data. Formal Outcomes measures what is actually happening to households financially, drawn entirely from regulatory administrative data. Formal outcomes reflect decisions households have already made or failures that have already occurred. Leading Indicators measures where conditions are heading. The platform’s leading indicator signals have been empirically validated against formal household stress outcomes using historical Australian and international data. The three tiers are combined into a composite score using a weighted arithmetic method with a continuous amplifier that ensures elevated cost pressure alone is insufficient to produce a high composite score without confirmation from formal outcomes or leading indicators.
Independence. The AHI is an independent publication. It accepts no advertising, no commercial partnerships, and no industry sponsorship. No commercial organisation influences the methodology or its outputs. The platform is founded and directed by Adjunct Associate Professor Graeme Hughes of Griffith University.

1
Cost Pressure: Eight essential spending categories (housing, groceries, transport, fuel, insurance, health, energy, telecommunications) are each scored against stress thresholds calibrated from Australian administrative data. Category weights reflect the ABS Household Expenditure Survey 2022–23.
2
Formal Outcomes: Administrative data signals measure what is actually happening to households financially — mortgage arrears (APRA), personal insolvency (AFSA), energy hardship (AER), debt serviceability (RBA), household saving (ABS National Accounts), and credit growth (RBA). Administrative records are preferred because they reflect actual decisions, not survey responses.
3
Leading Indicators: Forward-looking signals drawn from ABS Labour Force, ABS Retail Trade, ABS Lending Indicators, and RBA business conditions data. Signal weights are empirically derived from validation against historical Australian and comparable international household stress episodes.
4
Composite score: The three tier scores are combined arithmetically with a continuous amplifier that scales the composite upward when pressure is elevated across multiple tiers simultaneously. Scores are reported to one decimal place on a 0–100 scale anchored to 2019 pre-pandemic conditions.
