This essay aims to explore the migration from Kalmar and Karlskrona city parishes during the first half of the 20th century divided into three intervals 1915-1920, 1930-1935 and 1943-1948. As stated above the main part of the study aims to map the migration flows to and from Kalmar and Karlskrona and furthermore compare the empirical data to Swedish national statistics. To be able to correctly compare the data gathered the empirical data of the essay is divided into four variables; age, sex, professional or other titles and whether the individuals migrated alone or with family. A comparison between Kalmar, Karlskrona and national statistics will be made to investigate whether the two city parishes are able to act as representations of the national statistics or if the two city parishes have a different outcome than what the national statistical data presents. The results show that the migratory patterns differ both between Kalmar and Karlskrona and in the national statistics of migration in regard to the city parishes. With the usage of migration theories and perspectives such as the migration transition, secondary labor market theory and push- and pull perspective and concepts such as voluntary migration and chain migration the study was able to both analyze and understand the data provided from the city parishes archives
