Hi everyone!
I would like to select countries for a cross-cultural study (it's my PhD project) based on the level of ethnolinguistic/cultural fractionalization/polarization, but cannot find a good index for that. Alesina's (2003) index is commonly used, but it is based on data from very different time points. Fearon's (2003) index looks a bit better, but the data that is used there is from the beginning of 90's. I wasn't able to find any index that would be based on newer data and would cover not only Europe, but also the rest of the world. Did anyone come across something like that?
