Births, deaths and moves are ISTAT's population balance, from the municipal registers, from 2019: a place's migration counts moves from other municipalities and from abroad, Italy's only those to and from abroad. Italy counts no homes finished, so homes permitted in new residential buildings stand in; most are finished two to three years later, and some never are. A home houses a household, not a person: two or three new residents per new home is roughly one home per new household.
