This paper is written in a collaboration with the Swedish Police in Landskrona. Based on their request to know more about the decreasing crime rates in Landskrona the purpose of the study is to highlight and create knowledge about possible explanations for these changes. The study consists of semi-structured interviews with different stakeholders from the Police, Municipality and the County Administrative Board. These individuals’ perceptions are used in order to discover what is happening in Landskrona. During the examined ten-year period it has been possible to distinguish a downward trend in terms of reported crimes in Landskrona. The result shows several possible explanations to this trend but, the most consistent findings are; effective collaboration mainly between the Police and the municipality, various investments toward youths both social and educational and huge investments in urban development. These investments are used as possible explanations for the changes in reported crime in Landskrona and perceived to play a pivotal role when it comes to understand the decreasing crime rates.
