Ethnic Power Relations dataset

The Ethnic Power Relations (EPR) dataset identifies 733 politically relevant ethnic groups in 155 sovereign states from 1946 to 2005, provides group size estimates, codes the level of access to the executive branch by representatives of these groups in each year, and notes if an armed conflict was fought in the name of a particular ethnic group. The war identification numbers correspond to those in the Ethnic Armed Conflict data-set.族群权力关系（Ethnic Power Relations, EPR）数据集识别了1946年至2005年间155个主权国家内的733个具有政治相关性的族群，提供族群规模估算数据，逐年对各群体代表获取行政分支权限的等级进行编码，并记录是否存在以特定族群名义发起的武装冲突。该数据集所使用的冲突标识编号与族群武装冲突数据集（Ethnic Armed Conflict dataset）中的编号保持一致。
