About this chart

The UN projects Belgium to reach 11.06 million people in 2100, below its 2023 estimate of 11.71 million. At the estimated endpoint, Netherlands has 18.09 million people against 11.71 million for Belgium. In 1950, the corresponding totals were 10.11 million for Netherlands and 8.62 million for Belgium. All values are population totals, rather than population density or annual growth rates.

By 2100, the UN medium-variant projection reaches 17.51 million people for Netherlands and 11.06 million for Belgium. 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.
