Number and Population of Municipalities by Size of Population (1898-Oct. 1, 1930) : Statistical Yearbook of Imperial Japan 54 (1935) Table 20

PERIOD: At the end of every 5 years from 1898 to 1918. As of October 1st every 5 years from 1920 to 1930. NOTE: Individual towns and villages that were combined under the Municipal Government Act are counted separately. However, in the surveys in 1898 and 1903, the combined villages of Oshima County in Kagoshima Prefecture were not surveyed individually and are recorded as one combined village. The population figures in the columns for 1898 year-end to 1913 year-end are the "type A" de facto population  (see page 17 of the 1916 Statistical Yearbook of Imperial Japan), while the figures for 1920, 1925, and 1930 are from the Population Censuses conducted in those years. .

周期：自1898年至1918年的每五年末，以及自1920年至1930年的每五年10月1日。备注：根据市町村制合并的个别城镇和村庄分别计数。然而，在1898年和1903年的调查中，鹿儿岛县大島郡的合并村庄并未单独进行调查，而是以一个合并村庄的形式记录。1898年年末至1913年年末的各列人口数据为‘A型’事实人口（参见1916年《大正帝国统计年鉴》第17页），而1920年、1925年和1930年的数据则来自那一年进行的全国人口普查。来源：[内阁统计局调查]。
