Subjects (296) of both sexes comprising 68 Europeans and 228 Indians, resident in India, were studied with respect to factors which may influence the total and differential leukocyte counts. No consistent variation of the total and differential leukocyte counts was observed between the Europeans and Indians. Male South Indian students had a significantly higher total leukocyte count than the male North Indian students (P < 0.01). A significant decline of the number of monocytes and eosinophils was observed with advancing age among Indians (P < 0.01). The packed cell volume was significantly correlated with the monocyte (P < 0.005) and eosinophil counts (P < 0.05). There was a tendency towards increased neutrophil counts in the winter, although this finding was not consistent in all groups studied. Among Europeans, there was a tendency towards a decrease of neutrophil counts with the duration of stay in India. The total and differential leukocyte counts were not correlated with socio-economic status, diet, physique, blood groups (ABO and Rh), Hb concentration, red cell indices, erythrocyte sedimentation rate and serum protein fractions.
