Claims to have made progress are a mainstay of organizational reputation management. However, confusing and contradictory performance expectations can make progress difficult to locate among a police department’s priorities. A case study of the Chicago Police Department’s front-facing pronouncements over more than a century and a half clarifies how a bureaucracy works, stretches, and repackages “progress” to resolve those confusions and contradictions. We find that progress claims featured more prominently and fervently during moments when the department had reason to believe its legitimacy was threatened. Within that general pattern, we also find specific patterns in the form that progress claims took. We observe the stable reliance on two techniques to gesture toward progress the police either promised to enact or that it claimed it had already delivered: the police shifted goalposts by cycling through inconsistent measures of favorable performance from one year to the next, and they drummed crises to dramatize the obstacles that favorable performance required them to overcome. By showing how both techniques reinforced one another, we clarify how a police department “makes” progress.

The Fragmented Evolution of Racial Integration since the Civil Rights Movement

We argue that existing studies underestimate the degree to which racial change leads to residential segregation in post-Civil Rights American neighborhoods. This is because previous studies only measure the presence of racial groups in neighborhoods, not the degree of integration among those groups. As a result, those studies do not detect gradual racial succession that ends in racially segregated neighborhoods. We demonstrate how a new approach based on growth mixture models can be used to identify patterns of racial change that distinguish between durable integration and gradual racial succession. We use this approach to identify common trajectories of neighborhood racial change among blacks, whites, Latinos, and Asians from 1970 to 2010 in the New York, Los Angeles, Chicago, and Houston metropolitan areas. We show that many nominally integrated neighborhoods have experienced gradual succession. For blacks, this succession has caused the gradual concentric diffusion of the ghetto; in contrast, Latino and Asian growth has dispersed throughout both cities and suburbs in the metropolitan areas. Durable integration has come about largely in the suburbs.
