Frequently Asked Questions
How do I get access to data in SwedPop?
SwedPop data is delivered to registered users through the Online Data Retrieval Tool. You can register for free on the website swedpop.se. Users select the variables and samples they are interested in, and the system creates a custom-made dataset containing the requested information. Data is provided free of charge.
How do I get access to restricted data?
During 2026, a new interface will be introduced that will allow researchers to request data that constitutes personal data under the GDPR and requires disclosure assessment under the Public Access to Information and Secrecy Act. Until then, requests for restricted data must be submitted directly to each data holder.
Where should I start, when selecting variables and samples?
Start by selecting databases, cohort criteria, and variables. Then choose the format for the dataset. Your dataset will appear on the dashboard with a name, timestamp and download button. You must download the dataset and analyse it on your local machine.
The dataset is available for download for four days. To access the same dataset after this period, click the dataset name on the dashboard and regenerate it. This will create a new dataset.
For more detailed information, please refer to the User Guide.
What format is the data available in?
You can obtain your dataset in two formats: the Intermediate Data Structure (IDS) and a rectangular format. By default, the Online Data Retrieval Tool generates zipped CSV files that can easily be imported into statistical software packages.
Why are there more variables in my dataset than I selected?
Some variables constitute standard variables and are automatically included in every dataset. In the IDS format, data always includes identification of the database(s) from which the data is retrieved, an individual ID, source, and timestamps. In the rectangular format data includes corresponding identifying and structural variables.
In some cases, additional variables are included to provide complete information. The occupational HISCO information, for example, includes four variables: HISCO-code, relation, status and product. Please consult the documentation for more information.
How long does a data retrieval take?
The retrieval time depends on the size of the dataset and technical factors, such as the number of simultaneous orders. The system sends an email when the dataset is complete and ready to be downloaded.
Can I recreate a previous data retrieval?
All data selections are saved and can be recreated or modified. Since new versions of SwedPop data are published regularly, please note that the contents of a dataset may differ if it is based on a later version of the database. The current version number of SwedPop data is displayed on the dashboard and can also be found in the metadata table of downloaded datasets.
What may SwedPop data be used for?
SwedPop data may be used for scientific research in accordance with European Union and national data protection laws. Read more about Terms and Conditions of Use here.
Can I use SwedPop data for genealogy?
