Comparative Territorial Autonomy Database

About CTAD

The Comparative Territorial Autonomy Database (CTAD) is the first-ever comparative dataset that adopts “territorial autonomy” as an explicit unit of analysis. It codes the political, social, and institutional data of territorial autonomies with a view to facilitating comparative, quantitative analysis.

The dataset was compiled by a transnational team of scholars in 2021 and was published as part of the Routledge Handbook of Comparative Territorial Autonomies in 2022.

ASEN is pleased to have the chance to host and release CTAD through our website.
