Data obtained from interviews with Black families during a 1971 interstate regional project in Texas provided the basis for this study, which explores the nature and magnitude of metropolitan (M) and nonmetropolitan (NM) differentials in disability. The following questions suggest the research objectives: (1) Do NM Black families experience more frequent and higher degrees of disability than M Black families? (2) Does the M-NM differential increase as education of homemaker, level of income, and occupational status of the main breadwinner increase? and (3) Does family disability decrease under the above conditions? Selected from a large M center, a small town, and 2 small open-country villages, the respondents were Negro female homemakers between the ages of 18 and 65 having children in the household. It was concluded that M and NM Black families were similar in exhibiting a low degree of family disability, and the NM-M differences observed in degree of family disability were not patterned consistently as expected through levels of education, income, or occupation. While not patterned consistently, the impact of these social attributes on disability did appear to vary often by NM-M residence. Recommendations for further research include finding more accurate instruments to record individual disability and alternative methods of securing responses and calculating the family disability index.
