Terrorist campaigns and the growth of the Muslim population: a reply to Clara Egger and Raul Magni-Berton

Abstract I am delighted to see that my study on the effect of terrorist campaigns on the growth of Muslim populations has intrigued Egger and Magni-Berton. After discussing potential theoretical and methodological shortcomings in my study, Egger and Magni-Berton conclude that there is no empirical support for the positive relationship between terror attacks and Muslim populations. Their approach of separating terrorism into Islamist and non-Islamist terrorism is an effort to advance the contemporary research on the nexus between terrorism and Islam. In this re-examination, I show that Egger and Magni-Berton's conclusion is based on two limitations: theoretically unfounded and empirically inadequate. After remedying these limitations step by step, I reconfirm that a series of terrorist activities collectively serve as an explanation for the growth of the worldwide Muslim population. Future research can offer additional evidence to understand whether there is a significant and positive relationship between Islamist terrorism and the growth of Muslim populations.
