GEOGRAPHICAL DISTRIBUTION AND RACIAL DISTRIBUTION OF PELLAGRA IN SPARTANBURG COUNTY
The geographical distribution of pellagra in Spartanburg County was considered in detail in the First Progress Report.1 In general, it was found that morbidity tended to vary directly with congestion of population, although this relationship was markedly disturbed by other factors. The villages of the cotton mills showed the highest morbidity and, when their population was excluded from the figures, the morbidity rate for the city dwellers was about the same as in the neighboring rural population, although somewhat above the morbidity of the rural population of the county as a whole.The cases of pellagra in Spartanburg County on our records at the end of 1912 included 257 white persons and twenty-five colored (negro and mixed blood), representing a morbidity of 45 per 10,000 whites and 9.5 per 10,000 colored population. This difference was not regarded
