I regularly get asked whether I’d be willing to share my data on the political representation of ethnic groups in national legislatures. The answer always is yes, as I believe in sharing data. Apart from the appendices in my 2009 article and 2013 monograph, the data are available on my Dataverse. There you can find a spreadsheet with the numbers behind the representation scores. As this is an ongoing project of mine, I do from time to time update my database with better estimates, and also expand coverage. This also means that I’d appreciate possible corrections.
