The Psychiatric Investigation by Census for Two Districts in Chiba Prefecture

Abstract

The investigation was performed in a city and a village in Chiba prefecture in July 1960. The finding is follows:
1) There were found more schizophrenics in the city than in the village. This may be partly caused of heredobiological factors as has often been suggested up to now, yet it is also necessary to notice whether the circumstances may influenced the adjustment of their social life.
2) The alcoholic were divided into four groups according to their brinking pattern, and that percentage of each groups of alcoholic are follows:
city village
(1) occasional drinker 51.0% 46.4%
(2) habitual drinker 39.8 44.1
(3) addictional drinker 6.3 7.0
(4) chronic alcoholism 2.9 2.5
These results showed ehat there were no great differenses between two districts and the criminals were found more in III and IV group than in the others.
This suggests some relationships between alcohol and crime.
3) In the low culturized district there were found more criminals, but this fact has need of the further investigations from the viewpoint of social psychiatry
