AbstractUsing regression analysis of community areas of Chicago, patterns of homicide, robbery, and aggravated assault are analyzed for the mid‐1970s. It is found that neighborhoods in which very poor and middle‐class people live in close proximity are those in which rates of all three types of criminal violence are highest. Of all demographic and crime variables analyzed, proximity was by far the most strongly related to crime rates. This relationship was taken to be another indicator of the extreme burden placed on blacks in heavily segregated cities of the urban North.

This paper discusses collective bargaining in the United States over matters of job security, employment creation, and firm competitiveness. It first points out that US policy on economic issues is oriented toward facilitating the operation of markets; therefore, there is almost no public policy toward job security, employment creation, and competitiveness on which collective bargaining can build. Within the collective bargaining system, government policy merely enables unions and employers bargain over job security, employment creation, and firm competitiveness; it neither requires it nor even encourages it. Incidence of such use of collective bargaining thus varies by industry, with occasional use for competitiveness, but rare use for job creation. An exception is the automobile assembly industry, which is highlighted.

Why do robbers choose a particular area to commit an offense? Do they rob close to home? Do they search for areas with suitable and attractive targets? What keeps them away from certain areas? To answer these questions, a model is developed of how robbers choose target areas. The model draws on various theoretical and empirical traditions, which include environmental criminology, journey to crime research, gang research, and social disorganization theory. Testing the model on cleared robbery cases in Chicago in the years 1996–1998, we demonstrate that robbery location choice is related to characteristics of target areas, to areas where offenders live, to joint characteristics of the resident and target areas, and to characteristics of the offenders themselves. The presence of illegal markets and other crime generators and crime attractors make areas attractive for robbers, whereas collective efficacy seems to keep them out. Distance as well as racial and ethnic segregation restrict the mobility of offenders.
