This study first empirically compares the performances of several representative methods for GPW projection (forecasting), subsequently it performs scenario creations of Japanese residential electricity demand for 2050 using the population projections, derived using the models, multiplied by an intensity. ...
Scenarios of future population at the grid level (e.g., 1km2) is very important for various types of regional planning, including energy planning. Though the most often used method for population projection is the so-called cohort-component method, if our focus is world level, not country ...
A dire trend in graying Japan is expected to worsen over the coming decades, with close to half of all households forecast to have only one member living alone in 2050. That prediction was released on April 12 by the National Institute of Population and Social Security Research. While the es...
This sounds a bit misleading. Japan’s over 75 population in 2015 was around 18.7 million. The projection for 2045 is around 23 million. The number of over 90s most likely to require care will double compared to now, but will also peak before 2050 and start going down after that. ...

In 2022, Japan’s total population was estimated at approximately 124.9 million, decreasing for the 12th consecutive year.11 Only the Tokyo Metropolitan Area saw an increase in population compared to 2021, at 0.2%; all other prefectures saw declines ranging from 0.01% to 1.59%.11 92% of the...
In 2022, the number fell below the 800,000 mark for the first time since 1899, when record-keeping began. The Asahi Shimbun’s prediction for 2023 also dropped below 739,000, an estimate released in April by the National Institute of Population and Social Security Research. ...
Under this scenario, it would be necessary to raise the retirement age to 77, if the 4.8 level were to be sustained in 2050.** A different UN medium variant projection which assumes that Japan would want to maintain its predicted 2005 population peak of 127.5 million shows that this could ...
3. In the BaU-DefDem scenario, total final energy decreases over time due to population decline and autonomous energy efficiency improvement, reaching approximately 10 EJ in 2050. Although the level of energy service demand in the MCS-DefDem scenarios is identical to that in the BaU scenario, ...
