About this chart

Italy is below its earlier estimated peak of 60.66 million people in 2014: its 2023 total is 59.50 million. The comparison still puts Italy ahead of Spain, with 59.50 million and 47.91 million respectively. In 1950, the corresponding totals were 46.39 million for Italy and 28.08 million for Spain. All values are population totals, rather than population density or annual growth rates.

By 2100, the UN medium-variant projection reaches 35.38 million people for Italy and 33.13 million for Spain. 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.
