Material from a community survey carried out in rural areas of Karnataka by the National Tuberculosis Institute (NTI) Bangalore has been analysed in an attempt to identify significant categories of the population that may yield higher proportion of cases. In all, 170 cases diagnosed among 61,581 persons have been distributed by their role, (i.e., head of family (HOF) or not), kinship, (relationship to the HOF) by age and sex. It has been observed that a comparatively small size of HOF and sex. It has been observed that a comparatively small size of HOF-Male Population (16.9%) would contain 55.9% of the total cases prevalent in the entire X-rayed population. On the other hand, the broad category other than HOF-male would have case content relatively much less in proportion to their population size. Implication of the finding for house-to-house casefinding by Multipurpose Health Workers (HWs) is discussed, It is possible to obtain higher case yield from this selected group having a higher case content by confining symptom screening to this group which constitutes 30% of the population, aged 20 years and above. On the other hand, since cases are mostly in their normal visiting hours during day, as most of the HOF-Males may not be at home, and hence determined efforts have to be made by HWs to contact them during their bear-schedule.
