Everything an analysis can return, with its source, its reference year and how often it is updated. In short K-Stra’s data catalogue for Australia combines ABS population, census, income and spending statistics with a monthly places catalogue of businesses, property listings and any file you upload. Official statistics are spread onto 14.5 million address points and updated annually, businesses and listings monthly, and every table in the app carries its source and year. - Population and families - Work and employment - Income and spending - Markets and competition - Real estate - Your own data - Territory [Open the app](https://www.k-stra.com/a/?src=product-data) 01 · Population and families ## What population and family data does K-Stra include? Population, sex and age come from the latest official annual estimates. Everything else about residents and families comes from the 2021 Census, the only source that measures it. Source ABS Estimated Resident Population · ABS Census 2021 Reference year 2024 (population, sex, age) · 2021 (the rest) Update Annually, when ABS publishes Resolution Address point · 9 levels Used in People & Economy - Resident population · ERP 2024 - Males and females · ERP 2024 - Population by 15 five-year age classes, by sex · ERP 2024 - Average age, median age and old-age index · derived from the age classes - Population trend by council and average yearly change · ERP 2019–2024 - Families (census families: couples and one-parent families) and residents per family · Census 2021 - Residents born overseas · Census 2021, country of birth - Education level · Census 2021 - Marital status of residents aged 15 and over · Census 2021 - Dwellings and occupied dwellings · Census 2021 - Homes owned outright, with a mortgage or rented, and those in social housing · Census 2021 - Dwelling type: separate houses, semi-detached and townhouses, flats (and those in buildings of 4+ storeys) · Census 2021 - Cars per dwelling: none, one, two, three or more · Census 2021 - Area in km² and population density - Population by postcode and by council inside a catchment **Not available for Australia.** Births, deaths and migration balances and family trends are not published for these areas, so K-Stra does not show them for Australia. Residents are counted by country of birth, not by citizenship. Source note in the app: Population, sex and age: ABS annual estimates 2024; the other variables: ABS Census 2021. Spread onto addresses with the 2021 SA1 mesh, keeping each council’s total. 02 · Work and employment ## What employment data is available? Labour-force figures describe who is working, who is looking for work and who is outside the labour force, with the three standard rates. Source ABS Census 2021 Reference year 2021 Update Every census (five years) Resolution Address point · 9 levels Used in People & Economy - Labour force and people not in the labour force - Employed and unemployed residents - Activity, employment and unemployment rates Source note in the app: Population, sex and age: ABS annual estimates 2024; the other variables: ABS Census 2021. Spread onto addresses with the 2021 SA1 mesh, keeping each council’s total. 03 · Income and spending ## How does K-Stra measure income and spending? Two indices put every area on the same scale, where 100 is the Australian average. Spending in dollars is then calculated for any area from national accounts coefficients, so no figure is stored ready-made. Source ABS Personal Income in Australia (ATO/LEED) · ABS national accounts 5204.0 Reference year Income 2023 · spending coefficients FY2024-25 Update Annually, when ABS publishes Resolution Address point · 9 levels Used in People & Economy - Income index (NIR), 100 = Australian average · measured for 543 councils and 2,405 SA2 areas - Consumption index (NIC), derived from the income index - Income index by band, compared with the catchment and with Australia - Spending per head and total, in A$ a year, by COICOP 2018 category · 26 spending items for Australia - Potential market by band, in A$ million a year **Not available for Australia.** Household spending is not surveyed below state level, so the consumption index is calculated from income rather than measured. Income classes and business establishments are not available for Australia. Source note in the app: Income index from ABS Personal Income (ATO/LEED) 2023 where measured, K-Stra estimate elsewhere; 100 = Australian average. Spending per head = the area’s consumption index × ABS national accounts coefficients (5204.0, FY2024-25). 04 · Markets and competition ## What does K-Stra know about businesses and competitors? More than 2 million Australian businesses and stores, from the K-Stra places catalogue updated every month (October 2026), searchable by sector or by brand. For each sector, a spending model estimates demand, supply and opportunity at every inhabited address. Source K-Stra places catalogue · K-Stra sector model Reference year Refreshed with each monthly update Update Monthly Resolution Address point Used in Markets & Brands - Search by sector or by brand, with stores grouped under the brand they belong to - Demand, supply and opportunity for a sector, mapped address by address - Best 5 locations by opportunity and by market gap, at least 500 m apart - Number of stores by band, per resident and per km² - Store list with address, state, distance, travel time, rating and number of reviews - Coverage and cannibalisation between your stores and competitors - Spending captured by each store, from the sector model - Comparison of one to five candidate sites, including what each takes from your own stores 05 · Real estate ## Where do the property values come from? Australia has no official register of property values by zone, so K-Stra estimates them from sale and rental listings. Values are aggregated by postcode, and every sample states how many listings it rests on. Source Property portal listings Reference year Second half of 2026 Update Monthly Resolution Listing · postcode Used in Real Estate - Average and median asking price, and price per m² - Average and median rent - Gross rental yield - Distribution by property type and by floor-area band - Price trend as an index, 100 = first period - Number of listings used and a reliability score for every sample - Individual listings on the map: price, size, bedrooms, bathrooms, parking, type, suburb and dates Source note in the app: Property values and rents estimated from portal listings, second half of 2026. 06 · Your own data ## Which of my own data can I add? Stores, customers, prospects, sales reps and loyalty cards can be uploaded and analysed together with the national data. The Customer Loyalty and Sales modules work on these files.

Nine Australian administrative levels, from the whole country to the SA1 statistical area, plus the level that makes the difference: the single address.

All nine levels are in the data and can be imported into My Data; on the map, the labels follow the zoom from states down to suburbs. Of the 14.5 million address points, 8.9 million have at least one resident. A travel band adds up the addresses it reaches, so its edge passes between one street number and the next instead of cutting a statistical area in half. Address points from Overture Maps; residents spread with ABS data (K-Stra territory v5, 30 September 2026). Levels as of 30 September 2026. Checks ## How do you know the numbers add up? Spreading a figure onto addresses must not create or lose anyone. On 14 September 2026 the address-level population was summed council by council across Australia: all 545 councils with address points returned the official figure exactly, with a largest gap of 0 people. The national total is 2,490 people short of the official estimate. They are the residents of Christmas Island and the Cocos (Keeling) Islands, whose address map has not been loaded — a missing piece of map, stated openly rather than smoothed over. Councils checked 545 Largest gap 0 people Measured 14 September 2026, every council with address points, ABS 2024 estimates FAQ ## Questions about the data ### How often is the data in K-Stra updated? Businesses and property listings are refreshed every month. Official statistics change once a year at most, when the Australian Bureau of Statistics publishes a new edition; census variables change every five years. When newer data arrives, a saved analysis tells you so and offers to update it. ### How can figures be at address level when the census counts areas? Each area’s figures are spread onto its addresses in proportion to how many people each building can house, estimated from the road network and the size of the building. The census gives the shape inside each statistical area; the council’s latest estimate gives the total. ### Why don’t the SA4 areas of a state add up to the state total? Because they describe different years. States, councils, postcodes and suburbs carry the 2024 population estimate; SA1 to SA4 areas keep the 2021 Census count. The gap between the two is population growth, not an error. ### Is the income index measured or estimated? Measured wherever ABS publishes personal income: 543 councils and most SA2 areas. Elsewhere a K-Stra model estimates it. Tested against the measured councils, the model reaches a correlation of 0.49 and an average error of 10.3 index points, so it is used to rank areas, never in place of a measured value. ### Where do I see the source of a number in the app? Next to the title of every results table, with the year of the most recent data in it. Hovering over it shows the full source note, which is saved with the analysis together with its results. ### Can I download the figures for a whole administrative level? Yes. Import the areas of any of the nine levels into My Data with the figures you choose, then export them for free. The import costs 1 credit per 10,000 rows plus 1 credit per 1,000 values; the boundaries themselves stay in the app and are not exported.
