Rekisteriperusteisia

Rekisteriperusteisia is a Finnish term that translates to "register-based" in English. It refers to a research methodology or a data collection approach that utilizes existing registries or databases as the primary source of information. These registries are typically maintained by governmental or official bodies and contain systematically collected data on individuals, organizations, or events.

The use of register-based data allows researchers to study large populations over extended periods without the need for direct surveys or interviews. This can lead to more objective and comprehensive findings, as the data is often collected for administrative purposes and is less susceptible to recall bias or social desirability bias that can affect self-reported data. Examples of such registries include population registries, health registries (e.g., cancer registries, birth and death registries), education registries, and business registries.

Register-based research is particularly valuable in fields like public health, epidemiology, sociology, and economics. It enables the analysis of trends, the identification of risk factors, and the evaluation of the impact of policies or interventions on a population level. However, researchers must be aware of the limitations of register data, such as potential data quality issues, changes in registration practices over time, and privacy concerns. Ethical considerations and data protection are paramount when working with sensitive register information.
