(Animation)The diagram stops in a moment at 1940 because of no data for 1941`1943, and jumps to 1944. "Previous" and "Next" relate to years of data (See [Transition]). Fluttering in aged groups in 1944 and 1951-1954 is caused by no divisions of 5-year. Sudden expansion and contraction of 0-4 year group in 1944-1946 follow original data. (Scale)Unit of scale is 'million persons'. (Method of taking statistics)The statistics were taken from the civil registration before 1918, from the census result in census year after 1920 and estimation in other years. Attention is to be paid to the scope of Japan's area, people and time of statistics through about past 120 years.
