Retail data and research methods
Choose Australian retail evidence by the question it answers, then record coverage, periods, calculations and limits before drawing a conclusion.
Start retail research with a decision and a measurable question. Household spending, industry sales, survey answers and retailer transactions describe different groups and activities. Choose evidence that fits the question, and keep its limits beside the conclusion.
Define the question
Name the population, product or business group, geography, period and measure. “Did retail grow?” is too broad to guide a range decision. “Did spending in this defined household category change across these periods?” identifies a measure that can be checked. Record what result would change the decision before examining the figures.
Choose and read the evidence
| Evidence | Useful for | Limit |
|---|---|---|
| Household spending series | Spending in a published consumption category | Does not identify which retailer received it |
| Retail industry series | Activity among businesses in a defined industry | Does not identify which products drove it |
| Survey | What eligible respondents reported | Does not establish what they later bought |
| Retailer transactions | Purchases recorded by that retailer | Misses purchases elsewhere and rarely explains motive |
In Australia, the ABS Monthly Household Spending Indicator groups selected household consumption by purpose.
The former Retail Trade, Australia publication ended with the June 2025 reference period. Business Indicators, Australia supplies quarterly industry sales under another survey definition. A shared label such as “retail sales” does not make these series interchangeable.
Read the unit as carefully as the headline. Current-price dollars can change with prices, measured volume or product mix. A dollar movement is not necessarily a volume result. Check the category, geographic coverage, seasonal adjustment and release date before comparing figures.
Key Retail Data Sources in Australia: Purpose, Coverage and Limitations
- Household Spending Series (ABS MHSI)Measures final consumption by households; based on bank card, supermarket & vehicle sales data. Does not identify which retailer received spending.
- Retail Industry Series (ABS Business Indicators)Tracks business activity in defined industries; based on quarterly surveys of businesses with ABN registrations. Does not identify which products drove sales.
- Consumer SurveysCaptures self-reported behaviour from eligible respondents. Cannot confirm actual purchases or later actions.
- Retailer Transaction DataRecords actual purchases made at a specific retailer. Misses off-site purchases and rarely explains buyer motivation.
Trace the data behind an estimate
The ABS Monthly Household Spending Indicator (MHSI) estimates final consumption of goods and services by Australian households. It draws on aggregated, de-identified bank card transactions supplied by participating banks, supermarket transactions and new vehicle sales data. These inputs are aligned as closely as possible with the Household Final Consumption Expenditure concept used in the National Accounts.
The inputs arrive on different schedules: banks send transaction data soon after each calendar month ends, supermarkets provide weekly files, and VFACTS is supplied monthly by the Federal Chamber of Automotive Industries. The ABS benchmarks the MHSI to annual Household Final Consumption Expenditure and adjusts monthly estimates to address data gaps, including cash spending. An estimate is therefore not simply a count of card payments.
The indicator follows the COICOP consumption classification and publishes outputs for nine COICOP divisions, as well as Australia-wide and state and territory data. When choosing a comparison, match the published division and geography to the question; a broad total cannot by itself establish what happened within a narrower product group.
Evolution of Australian Retail Data Reporting

- Post-June 2025Transition to *Business Indicators, Australia* for quarterly industry sales data under new survey definition.
- OngoingABS Monthly Household Spending Indicator (MHSI) continues using de-identified transaction data from banks, supermarkets and VFACTS.

Check the population and exclusions
The MHSI inputs are not designed specifically for statistical purposes, and their scope differs from both Household Final Consumption Expenditure and retail-business turnover. Its consumption concept is aligned with Household Final Consumption Expenditure, but the source data do not capture Australian residents’ spending on goods and services offered outside Australia. Bank card data also exclude foreign-currency transactions where the card terminal is outside Australia.
Household Final Consumption Expenditure includes expenditure by resident non-profit institutions serving households, while the MHSI sources do not capture that expenditure.
Business Indicators, Australia covers income from sales of goods and services, wages and salaries, company profits, and the book value of inventories for selected industries. Its Quarterly Business Indicators Survey draws from the ABS Business Register, which is primarily based on Australian Business Number registrations to the Australian Business Register managed by the ATO.
The survey excludes micro non-employing businesses and public sector businesses, along with specified industries covered by other ABS publications. Its estimates therefore describe a defined business population, not every Australian business. Note these boundaries when using its industry sales data to check or contextualise a household spending result.
Pros and Cons of Using Retailer Transaction Data for Strategic Decisions
- ProsProvides precise, real-time records of actual purchases at a specific store or platform. Useful for inventory planning and pricing strategy.
- ConsMisses customer purchases elsewhere; does not capture motivations or intent; may not reflect broader market trends.
Keep a decision record
For each figure, retain the exact source or extract, its release date, the population and exclusions, reference period, unit, adjustment basis and calculation. Put the finding beside the decision it informs and a sentence about what it cannot establish. If two sources cover different groups, present their results separately.
A national movement can provide context for a retailer, but it cannot diagnose that retailer’s stock, prices or customers’ reasons for buying. Use the narrow finding to identify a local check, such as comparing the retailer’s own category sales and stock records over the same period. If the source later revises a value, revisit the calculation and the conclusion.
Steps to Evaluate Retail Research Evidence in Australia
- Define the question clearlySpecify population, product group, geography, time period, and measure (e.g., ‘Did grocery spending in NSW increase between Jan–Mar 2026?’)
- Choose the right evidenceMatch the source (e.g., MHSI, Business Indicators) to the question’s scope and limitations.
- Record all metadataDocument source, release date, reference period, unit, adjustment method, and exclusions.
- Compare with cautionTreat differences between sources as prompts for investigation—not proof of error.
- Revisit if revisedIf a source updates its figures, reassess your conclusion and calculations.
Make comparisons auditable
Retain enough detail for another reader to reproduce the calculation, including the exact published series and any adjustment applied.
Treat a difference between series as a prompt to investigate coverage, not as proof that one is wrong. Record any known scope mismatch and explain why the chosen evidence is fit for the decision.
