husstandsundersøkelser

Husstandsundersøkelser are systematic data collection efforts designed to gather information from individuals within private households. They are conducted by national statistical offices, research institutes, or international organizations to measure living conditions, household structure, income and wealth, employment, education, health, housing, and related social indicators.

Design and methods: They can be cross-sectional to provide a snapshot of a population or longitudinal (panel) to track changes over time. Sampling typically relies on population frames such as civil registries or census lists, with stratification and multi-stage clustering to ensure representativeness. Data collection uses face-to-face interviews, telephone interviews, online questionnaires, or mixed-mode approaches. Standardised questionnaires enable comparability across time and, in some cases, across borders. In some settings, microdata are linked to administrative records under strict privacy protections.

Content and outputs: Husstandsundersøkelser cover a range of topics, including income, wealth, employment, education, health, housing conditions, family composition, and social participation. Outputs include weighted estimates, tables, and dashboards published by statistical agencies. Where permitted, microdata may be released for research through controlled-access portals, often with anonymisation and data-use agreements.

Uses and significance: They provide essential input for official statistics, policy analysis, and program evaluation. They support international comparisons of living standards and social conditions, and they enable researchers to study trends in poverty, inequality, and life-course outcomes.

Limitations and ethics: Nonresponse, measurement error, and reporting biases can affect accuracy. Privacy and data protection laws govern collection, storage, and access to data, with emphasis on informed consent, anonymisation, and secure data handling.
