It is well Known that the consanguineous marriage plays an important role in the manifestation of recessive hereditary disease.<BR>All inhabitants in agricaltural area in Kawamata town in the northern part of Fukushima Prefecture were subject to a systemic survey on consaguineous marriage. The results obtained were as follows:<BR>1. Among Ojima, Otsunaki and Yamakiya districts, the preceding two districts showed about 8% of consanguineous marriage, but the percentage in Yamakiya district was as high as 16%.<BR>2. There were some hamlets which showed a high percentage of consanguineous marriage exceeding 20%.<BR>3. In Ojima district the percentage of consanguineous marriage showed a decreasing tendency in proportion to younger years of age, while no such a tendency was observed in Yamakiya distrct.<BR>The remakably high percentage of consanguineous marriage in Yamakiya district may be attributed to its geographical situation cold weather, high latitude and isolation from other districts are pointed out.<BR>The hamlets which showed high percentage of consanguineous marriage in the same district were located in places difficult of access. In addition, these hamlets were special communities which have been called leprosy hamlets. Such a social element as mentioned above should not be disregarded as one of the factors for the high percentage of consanguineous marriage.<BR>The absence of the decreasing tendency of consanguineous marriage in Yamakiya district, different from Ojima district, may be considered to indicate little change of cultural and traffic situation in the district since old times.
