rekisteripohjaisesti

rekisteripohjaisesti is a Finnish term that translates to "register-based" or "based on registers." It describes a method of data collection and analysis that relies on existing administrative registers rather than conducting new surveys. These registers are typically maintained by government agencies and contain information on individuals, businesses, or households, such as census data, tax records, social security information, and business directories.

Using register-based data offers several advantages. It can be more cost-effective and time-efficient than traditional survey methods, as the data is already collected for other administrative purposes. It also allows for longitudinal studies, as data can be linked over time for the same individuals or entities. Furthermore, register-based data can provide more comprehensive coverage and reduce response bias, as it captures information from the entire population covered by the registers.

However, register-based approaches also have potential limitations. The availability and quality of data depend on the completeness and accuracy of the administrative registers. Definitions and classifications used in registers may not always align perfectly with research needs, requiring careful data harmonization and transformation. Privacy concerns and data security are also important considerations when working with sensitive register data, necessitating robust anonymization and access control measures. In Finland, register-based statistics are widely used by agencies like Statistics Finland to produce official statistics across various domains.
