The purpose of this article is the meta-analysis of the studies couducted about ethnic problems in Iran. To collect necessary data, the authors used relevant keywords, consulted the universities graduate theses and visited relevant websites. Finaly, the studies which met the specified criteria were selected and necessary data to test hypotheses were extracted by a questionnaire prepared by the authors. 10 studies were selected for the calculation of effect size statistics and other necessary information. To calculate these effects, the authors used CMA2 registered software and analyzed the assumptions. The results show that in total, indentified independent variables were effective on political mobilization, integration and national identity. The combined effect size was 0.708 (0.708d =) that was statistically significant. Since this amount is in the range of 0.8 to 0.7 it is assessed in accordance with the category average Cohen. The results also show that variables such as a theoretical foundation, respecting the customs, traditions, religion and language of ethnic groups, appointing ethnic elite in political positions or adopting an interactive approach by government, emphasizing commonalities and differences between religions and feeling economic and cultural discrimination, have been statistically effective on the political mobilization for ethnic integration and national identity. It can be concluded that to achieve political mobilization for ethnic integration, national identity and national solidarity, reducing economic deprivation and discrimination, emphasizing religious commonalities and respecting the language and customs and laws related to ethnic groups should be considered.
