“…The United Nations Population Division (UN DESA, 2015) suggests that the global population of international migrants, i.e., people residing in a country other than their country of birth, has more than doubled since the year 2000 to about 244 million by 2015. Permanently moving to another country o↵ers valuable opportunities and gains for both migrants and their host societies (see, e.g., Boubtane and Dumont, 2013;Dustmann and Frattini, 2014;Zanfrini, 2016;Hainmueller, Hangartner and Pietrantuono, 2017), but states can also experience a number of di culties when trying to manage large numbers of migrants. Especially relevant to this research, there is a considerable body of work suggesting that population movements may have security implications for receiving countries (e.g., Algan et al, 2013;Bloemraad, Korteweg and Yurdakul, 2008;Hainmueller, Hangartner and Pietrantuono, 2017).…”
