Findings from the study show that the contemporary surge in immigration has been associated with the applauded decline in selected forms of criminal violence. Research in recent years has revisited the relationship between immigration and violent crime. However, the research is limited in that it has been based largely on cross-sectional analyses for a restricted range of geographic areas. To address this limitation, this study sought to obtain a more comprehensive understanding of whether immigration facilitated the observed decline in crime and considered areas classified as traditional immigrant destination cities and those that are emerging as such. Using time-series techniques and annual data for metropolitan areas over the 1994-2004 period, the study assessed the impact of changes in immigration on changes in violent crime rates.
