Some Researches on the Increasing Rate of Population in Japan. (First Report)

Abstract

From years ago the writer has been interested in the problem of the increaee and decrease of population (Bevölkkerungsbewegung), and tried some considerations about the matter. Of them here are described, b y way of preface to what he shall say henceforth, two passages, which are grounded. on the increasing rate of population between 27 years (1898-1925).
A. An outline of the increasing rate of Population in Japan.
On the distribution of the increasing rate of 12, 000 political units (mura, mati, si) the following three are fairly noticed.
1. High increase are seen in the urban districts, along with the commercial, industrial, mining and the fishing districts.
2. Among the agricultural districts the mountainous regions show high increase and the plains show .low increase or depopulation.
3. The eastern part of Japan increases more than the western part.
Fact i is a matter of course. Fact 2 is an interesting phenomena as against to those of Europe, where depopulation are seen in the mountainous regions, Fig. 1 and 2 show the fact 3 to some degree. At any rate we can notice these three in the Plate 1-map showing the increasing rate in the Tôhoku Tihô (northeastern district of Japan).
B. Correlative relation between the increasing rate and the density of population.
Among the distribution, increase, and movement of population certain relations are expected naturally. Mere the writer treats one of them, relation between the increasing rate and the density of population correlatively. Three examples are taken in. the Tohoku Tiho, and two european districts are added. In each case the writer desired to examine the relations about the pure (here, the agricultural) districts, but his intension was not equally executed between the former three and the latter two. Any how the results are:
_??_
In the former three We see negative correlations, and the reverse in the latter two The differences are applicable to that of Japan and Europe, he thoughts. The details shall be explained in the near future.
