This research study investigates the perceptions of a low income population in North Nashville, Tennessee. The specific purposes were to describe demographic and social-psychological characteristics of the population, as well as the population's perceptions and knowledge of health problems and facilities. The information was collected through interviews. A random sample of households was selected, and 108 interviews were completed (88 Negro and 20 white households). The Negro and Caucasian groups within the sample were shown to have rather different demographic characteristics; the Negro group, for example, was somewhat younger and slightly larger. The two groups were also found to report different patterns of health problems and treatment sought; the frequency of reported health problems, for example, was higher for whites. In both groups, health problems were most frequently attributed to unknown causes. The treatment of choice was to consult a physician. Payment by the individual for treatment was more likely for those in higher occupational levels, from 20 to 40 years old, and Negroes. Behavior in response to perceived health problems can be viewed as reflective of the responses and alternatives available to people.
