About this chart

The UN projects Chile to reach 13.43 million people in 2100, below its 2023 estimate of 19.66 million. At the estimated endpoint, Argentina has 45.54 million people against 19.66 million for Chile. In 1950, the corresponding totals were 17.02 million for Argentina and 6.63 million for Chile. All values are population totals, rather than population density or annual growth rates.

By 2100, the UN medium-variant projection reaches 38.26 million people for Argentina and 13.43 million for Chile. 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.
