Constitutional Power-Sharing Dataset (CPSD)
I am the creator of the Constitutional Power-Sharing Dataset. This dataset contains detailed indicators on formal power-sharing provisions found in state constitutions and autonomy statutes targeting politically significant ethnic minorities. The current version (v.1.2) codes institutions mandating the inclusion of minorities into national government as well as providing them with influence over political decision-making. It contains data for minorities settling in 174 countries and for the time period between 1945 and 2016. It can be found here. I have finished collecting a new, thoroughly updated version of the CPSD. This will cover not only inclusive institutions, but also autonomy provisions, economic accommodation, and cultural recognition. It will also encompass significantly more group years (~180 countries, 1945-2018). This new version will be published in 2021.
Significant Administrative Units Dataset (SAU)
For various projects, I also collected geo-referenced data on first-order administrative units and autonomous regions (at different administrative levels). For this purpose, I combined my own geo-coding based on historical maps with publicly-available data provided by GADM. The resulting dataset contains more than 8900 unique administrative unit-periods and enables a detailed investigation into spatial dynamics at the subnational level. I also used it to aggregate territorial power-sharing measures onto the ethnic group level for various CPSD indicators. A first version of this dataset will be released shortly.
Standardized attribution of survey responds to ethnic categories
To test the consequences of power-sharing for group-wise mass attitudes, I have devised a standardized and semi-automated attribution procedure of survey respondents to the ethnic categories used in the Ethnic Power Relations (EPR) dataset. This makes use of all available information on explicit self-identification, religion, language, race, and settlement area to calculate the probability that a respondent belongs to a given EPR group. The attributed data cover a large number of conventionally used and freely available mass surveys, including the World Values Survey, Afrobarometer, European Social Survey, Latinobarómetro, and others.
Democracy Barometer, Version 6
During my time as research associate at the Centre for Democracy Studies Aarau, I coordinated a team-based effort to update the Democracy Barometer, which comprises more than 100 indicators for 70 countries. My responsibilities also included data validation and management of the project webpage. The data can be found here.
Replication data for all publications I have worked on can be found here.
