Two large samples of data from blood donors in Yorkshire (N = 6,485) and S.W. England (N = 7,205) were analysed in detail to see whether there are any associations between ABO and Rh blood group, and sex, age, occupational classes and migration distance. Blood donors were classified as natives or migrants according to their birth place and place of residence at the time of sampling. With respect to migration status, sex, age, and migrational distance no significant association was found with ABO and Rh types. The few significant associations were observed in local sub-units and are considered to be due to random fluctuations of gene frequencies. A higher proportion of the 0 type in females than in males is found to be produced by admixture of migrants (with high 0) to the local residents of S.W. England. An increasing proportion of Rh in younger females may be explained by selectivity among blood donors. No consistency of trend was found between migration distance and blood group. However, the average distance of migration is longer among the A type donors. Exclusion of high distance migrants from the S.W. England sample reveals that the frequency of A type is still very high, thus the sources of long distance migrants of A type must be well distributed across the country. One other explanation of the high migration distance of A donors could be a disproportionate contribution of higher professional socio-economic groups, as they are high in A. With respect to socio-economic groups, it was found that in all sets of data the proportion of A in social classes I and II, is significantly higher than in social classes III-V, while with 0 the reverse is true.
