In our discussion of the causes of anti-Japanese agitation in California, it was made clear that the explanation of much of the trouble lies in the conditions of the Japanese themselves, such as congestion in particular localities and different manners and customs. The nationalistic policy of Japan was also pointed out as a factor making for resentment. What renders the situation unnecessarily complicated, leading to a general misunderstanding, is the employment of the issue in local politics--exploitation of the subject for private ends by agitators and propagandists. Then our study entered the heart of the California problem, the fact of the existing Japanese population. It was discovered that the rate of increase of Japanese population in California has been rapid, but that it shows a tendency to slow down, while the rate of increase of the entire population of the State shows a tendency to steady increase. We found that in comparison with the total number of Japanese in the United States the percentage of Japanese in California is remarkably high, nearly 60 per cent. of them being domiciled in that one State. Then we examined the factors--immigration, smuggling, and births--which contributed to the increase of the Japanese population in California. Under the subject of immigration it was made clear that the net gain from immigration has become small since the restrictive agreement was concluded, but that the number of those entering the country increased because the number of those who are passing through or temporarily visiting America has increased. We expressed our opinion that in order to quiet the excitement of the people of the Pacific Coast it is entirely desirable to stop sending Japanese immigrants to America. We have somewhat fully treated the subject of birth because it is a vital part of the question. It was discovered in the discussion that the birth rate of the Japanese in California is exceptionally high, due to the fact that a high percentage of the immigrants are in the prime of life and that the percentage of married people is remarkably high. In forecasting the future of the birth rate we stated that if immigration is stopped the present generation will in time pass out without being re-enforced, leaving behind American-born children, who, with higher culture and more even distribution with regard to age and marriage, will not multiply at nearly so high a rate as their parents. We concluded, therefore, that the present is a transitional period and that apprehension over the high birth rate is entirely unwarranted.
