In this paper, it was discussed how much the community differences contributed to the growth and development of children in physique and motor ability. The island, the housing development and the urban areas were picked out as sample localltles. Samples extracted from these three areas were 244 children of 4 years of age and 288 of 5 years of age. Then, 4 items of physique and 13 items of motor ability were measured in July, 1970. Their family situations were also surveyed with questionnaire at the same time. It was concluded that the average size of family was larger in the island than in other areas. As for the parents' schooling career, the percentage of senior high school and college graduates were more than 80% in the urban sample, but it was much smaller in the island and the housing development samples. The significant difference in terms of locality could not be found in physique, but the island sample seemed to be superior to others in motor coordination and flexibility. The urban sample : is superior to others in all motor ability items except motor coordination and flexibility. In all communities the age difference was very significant especially in stature and sitting height and also significant in most items of motor ability with some exceptions. The age difference could be observed to be very significant in the most items of physique and motor abilities in the urban sample, so it might be concluded that the development in motor ability were more conspicuous in urban than in others. The sex difference was not observed significantly in all communities, but boys were superior in ball throw and girls in ball bouncing. This could be inferred that the differencein play habits of both sexes' caused such differences. The most interesting problem to determine how much each variable that was validated to contribute to growth and development in general. This could be made out by applying more precise research techniques and the survey concerning more various items.
