The current study explores how neighborhood fear of crime ("worry about specific crimes") changes over time in neighborhoods with different levels of disadvantage. With a comparative design, 81 and 123- neighborhoods in two cities in Sweden are followed over a six-year period. Fear of crime trajectories are assessed through growth curve modeling. We consider how differences in neighborhood processes, such as social and physical disorder, might influence fear of crime levels. The results show that fear of crime increased over time in both cities and the increase was related to higher levels of physical disorder in several areas. Furthermore, the change differed depending on the neighborhood type - in highly disadvantaged neighborhoods, the fear was stable at a high level. In contrast, the largest increases in fear could be seen in the areas with the lowest disadvantage in both cities. Theoretical and practical implications are discussed.
