Migrations, in a broader sense, represent the spatial mobility of society. Through the theoretical part of this paper, in addition to defining the concept of migration and migrants, the causes of the migrant crisis that hit many European countries in 2015, including the Republic of Croatia, are presented. Through the concept of national security and the historical development of asylum policy, a clearer picture of the political challenges and the state response at the economic level have been obtained. On the other hand, the paper deals with social aspects, showing the representation of the topics such as migrant integration and the media response to the crisis. Through the attitudes and citizens’ perceptions about migrants and universal human rights during the migrant crisis, the humanitarian aspect was presented as a challenge that the receiving states had to deal with. 16 articles from journals dealing with issues and categories of economy, social policy and social aspect in response to the migrant crisis were analyzed. Researches conclude that the lack of quality communication and cooperation between member states are the cause of the problems of reception and integration of migrants.
