About

Census-grade Australian demographics, on demand.

AUSynth turns the Australian Bureau of Statistics Census into two things researchers, analysts, and product teams actually want: a stream of realistic synthetic individuals you can model however you like, and a marketplace of pre-built statistical reports.

AUSynth is a product of Verosynthea — our company building privacy-safe synthetic data and statistical insight products for Australia and beyond.

Why this exists

Census microdata is the gold standard for understanding the population — but it's expensive to access, slow to deliver, and burdened with confidentiality rules that make modern data work (training models, building dashboards, sharing demos) painful.

AUSynth fills the gap. We generate statistically faithful synthetic records calibrated to the latest ABS Census, then ship them through a clean API and a friendly UI. No privacy approvals, no waiting months, no PhD in records linkage required.

Our approach

We use Gibbs MCMC sampling across ABS conditional distributions, calibrated to the 2021 Census and adjusted to the current year using published population, wage, and price indices. Generated records are filtered against a suite of pairwise validation rules to eliminate impossible combinations.

We publish quality metrics openly: see Quality benchmarks for SRMSE scores per dataset, known limitations, and how we handle small suburbs.

What we won't do

  • We do not claim to represent real individuals. No AUSynth row corresponds to a specific person.
  • We do not sell or share customer query data. Aggregated usage statistics never identify any user.
  • We do not lock data behind subscriptions. You pay for what you download, credits never expire, and outputs are yours to use commercially.
