Is Italy's Native Population Being Replaced?
How collapsing native births, immigration and mixed families are reshaping the cradle.
Over the last quarter century Italy has gone from a country where almost every newborn had two Italian parents to one where a growing share of babies has at least one foreign parent. At the same time, the total number of births has collapsed.
Debates about “population replacement” usually focus on immigration. But if you look at the data, the story is more complicated and, in some ways, more unsettling: a sharp fall in births to two Italian parents, a rise (and then partial decline) in births to two foreign parents, and a steady, persistent increase in children born to mixed Italian–foreign couples.
In this post I walk through ISTAT birth statistics by parental citizenship from 1999 to 2024 and show how these trends fit together. The charts later on make the pattern hard to ignore: Italy is not being transformed by one sudden wave, but by the combination of native collapse, immigration, and the quiet growth of mixed families.
1. What the data measure
The ISTAT tables classify births in four groups, according to the citizenship of the parents:
Both Italian parents
Both foreign parents
Italian father, foreign mother
Foreign father, Italian mother
In the third and fourth plots I keep all four groups. In the first two plots I merge the two mixed categories into a single group called “Italian + foreign parent”.
Note that this is a classification by citizenship of the parents, not by “ethnicity” of the child. Many children born to foreign parents will later become Italian citizens. So when I use shorthand like “native” I am really referring to births to two Italian-citizen parents.
What comes next is the part people argue about: the actual numbers, the curves, and the demographic shifts nobody shows in public debates.
