Abstract: | Researchers in the social indicator movement are increasingly aware of the value of obtaining both subjective and objective measures. At the same time there is a recognition of the need to understand relationships between the types of measures. Studies utilizing both subjective and objective measures indicate that while relationships between them exist, relationships are often not strong. This paper suggests several explanations for such imperfect relationships. One is scale discordance, a term used to recognize that the territorial base of an individual's subjective evaluation may not coincide with the boundaries of the unites used for the collection of objective data. Using data from a metropolitan area study, relationships between objective measures of crime and respondents' feelings of safety are examined for people whose perceptions of neighborhoods vary in size. The hypothesis that the relationship between the objective and subjective measures is stronger among individuals whose view of neighborhood size is in line with the relatively large territorial base for objective crime statistics is tested and found to be correct. Implications of the findings for research and policy making are discussed. |
