This study intends to study how the Social Democrats' (S) migration policy changed between 2014 and 2018. Comparison is made through a text analysis of election manifestos to describe S's stance after the refugee crisis in 2015 in relation to refugees and migration. S worked up the 'problem' over the years and as solution policy changes were carried out in the economic, social and political contexts in connection with the state's situation, where ideas and beliefs were based on the previous experiences and events. The study will be carried out by describing and following up the change in S migration policy between 2014 and 2018 in Bacchi's constructivist perspective on ideas and problem formulations in what concepts represent. This approach is regarded as a process that is to some extent continuously socially constructed by the exchange of opinions of policy actors. These are ideas that help policy actors create meaning and understanding of the world around them, and thus they form a basis for which interests and action options the policy actors act for and against in the policy process (Ohlsson, et.al, 2019:259). That is, they are ideas that give policy actors a purpose of understanding what the policy problem is and what the solutions are. The idea and ideology analysis method is used in this study to be able to compare, see and understand the importance of ideas in the creation of politics, what interaction and non-interaction between ideas means and why this is important to follow up in connection with the state's situation. To understand how ideas and concepts were problematized and social formulated through time in connection with the state's situation, the three text analytical questions of Bacchi's WPR approach were chosen which enable interpretation of the background knowledge, underlying assumptions made by S all political proposals.
