CLAIR-HD gathered these schemes to create an overview of the existing languages used in historical demography. The state of the field was summarised in 2024 by Mourits, Stapel, and Riswick.
&lt;br>
&lt;br>
This database contains &lt;br>
 - An output table that summarise how variables are named within historical demography.&lt;br>
 - An output table that shows the existing open access conversion tables.&lt;br>
 - The documentation of IDS, Mosaic, and Persons in Context on which the schema table is based. See also https://www.ipums.org, https://mosaic.ipums.org/, https://www.nappdata.org/, and https://personsincontext.org/ for more information. &lt;br>
- The documentation of the conversion tables on which the conversion table overview is based. The related output table contains links to the relevant produce pages.
