Welcome to the website for the Irvine Laboratory for the Study of Space and Crime (ILSSC) in the Department of Criminology, Law & Society at the University of California, Irvine. Our group is dedicated to researching the social ecology of crime at all levels of analysis including street segments, blocks, neighborhoods, cities, counties, and metropolitan areas.

Director Dr. Kubrin named American Society of Criminology Fellow!

Director of ILSSC Dr. Charis E. Kubrin has been selected as an American Society of Criminology (ASC) Fellow. The status is given to those ASC members who have achieved distinction in criminology. It recognizes people who have made a scholarly contribution to the intellectual life of the discipline, whether in the form of a singular, major piece of scholarship or cumulative scholarly contribution. In addition, a Fellow must have made a significant contribution to the field through the career development of other criminologists and/or through organizational activities within the ASC. Kubrin will be recognized in San Francisco during the 2019 ASC Annual Meeting in November. [Read more…]

Lab publication for new way to measure neighborhoods: Street egohoods

Defining “neighborhoods” is challenging for researchers. In prior research lab members Dr. Hipp and Dr. Adam Boessen proposed a novel measure, termed “egohoods”, that captures the area surrounding a particular block (based on straight-line distance). This new study extends this idea by explicitly incorporating the street network into the measure. This approach measures street egohoods based on the local street block, and then all adjacent streets. A second definition includes all street blocks one or two streets away from the focal block. We believe that these are plausible “neighborhoods” since residents can easily come into contact one or two street blocks away from their own street block. The approach is demonstrated using data for the Southern California region, we find that this measure of immigrant neighborhoods often exhibits a robust negative relationship with levels of crime.

Lab publication on new measure of immigrant neighborhoods

Studies typically measure immigrant neighborhoods based on the composition of the residential population. However, although ethnic businesses are an important component of immigrant neighborhoods, scholars often do not consider them when constructing measures of these neighborhoods. This study proposes a novel way to mesaure immigrant neighborhoods that combines information about the residential population, the presence of ethnic businesses, and the spatial distribution of these measures for creating what we term immigrant ethnic activity space (IEAS). Using data for the Southern California region, we find that this measure of immigrant neighborhoods often exhibits a robust negative relationship with levels of crime.
