🤖 AI Summary
This study addresses the urgent need for high-accuracy demographic and socioeconomic indicators under budget constraints by developing an AI-driven framework that ensures credibility, privacy preservation, and statistical validity. Integrating the United Nations’ official statistics principles with the HLG-MOS algorithmic quality standards, the work proposes a verifiable and auditable AI assessment checklist and guides the development of the MiniMax hierarchical Bayesian sampling algorithm. Validated through Monte Carlo simulations, synthetic populations, and real census microdata, the approach achieves an 80% reduction in sample size while meeting precision requirements on synthetic labor data and enables a 90% sample reduction on the 2021 Australian Census data, yielding national point estimates with errors below 1%. This significantly enhances the efficiency and reliability of official statistics production.
📝 Abstract
To meet growing demand for granular demographic and socioeconomic indicators under tighter budgets, national statistical offices must continually develop new methods. These include using big data, satellite imagery, and transactional sources to improve or redesign data collection. Artificial intelligence can support this work, but algorithms generated with AI should not be trusted for production without rigorous verification.
This paper focuses on two foundations of trust in the use of AI in official statistics: independent statistical verification before production use, and disciplined protection of respondent confidentiality during development and testing. The approach is illustrated through the author's experience directing AI to construct and implement a Mini Max Hierarchical Bayes sampling algorithm. Applied to a synthetic labour force population, the method met all specified precision targets while reducing the required sample size by 80 percent, as confirmed by a Monte Carlo study with 1000 replications. Applied to 2021 Australian Census microdata, it achieved a 90 percent reduction while producing national point estimates accurate to well below 1 percent.
The paper concludes with a practical evaluation checklist aligned with the UN Fundamental Principles of Official Statistics and the HLG MOS Quality Framework for Statistical Algorithms.
