  • Germany: 69.85M in 1950, 70.90M in 2100 (projected). The latest estimate is 84.55M in 2023. It peaked at 84.55M in 2023.

About this chart

Japan is below its earlier estimated peak of 128.19 million people in 2009: its 2023 total is 124.37 million. The comparison still puts Japan ahead of Germany, with 124.37 million and 84.55 million respectively. In 1950, the corresponding totals were 86.44 million for Japan and 69.85 million for Germany. All values are population totals, rather than population density or annual growth rates.

By 2100, the UN medium-variant projection reaches 76.85 million people for Japan and 70.90 million for Germany. Estimates end in 2023; later values are conditional projections rather than observed counts. Future fertility, mortality and migration can move the eventual totals away from this path. Comparing the same projection variant keeps the two countries on a consistent basis.
