Variables and Formats

SwedPop data can be retrieved in two output formats -IDS and Rectangular. The variables included differ depending on which format is selected. Detailed specifications of the variables included in each format are provided below.

IDS -Intermediate Data Structure

IDS is a common output format for databases containing longitudinal and non-aggregated information on persons, families and households. IDS has been developed by scholars in an ESF Research Networking Programme called European Historical Population Samples Network and forms an integrated and joint interface between databases in order to transcend regional and national differences. More information about IDS can be found here.

Rectangular Format

SwedPop datasets in rectangular format are organized in a spreadsheet-like structure, where each row represents an individual record and each column represents a fixed attribute.

This standardized format can be readily imported into statistical software and is well suited for analysis using tools such as SQL, Python and R.
