イタリアの人口は2021年の時点で59,169,131人であった[6]。これは世界25位にあたり、欧州連合ではドイツ、フランスに次ぐ3位である。
イタリアの合計特殊出生率は世界的にみても低位である。1977年以降は人口置換水準から大きく下がっており、1995年には史上最低の1.19を記録した[7]。21世紀以降、移民の流入の影響などもあり回復傾向に向かったものの、2020年の数値は1.24であり依然として非常に低い。平均寿命の長さも相まってイタリアの高齢化率は23.5%に達し、日本に次いで世界2位の高さである。1993年以降は死亡数が出生数を上回る人口の自然減が続いている。
外国人人口は2019年時点で5,225,503人で、総人口の8.5%を占める。このうち83％が経済的に発展した北部に住んでいる。
主要な都市
最大の都市は首都ローマである。州別で最も人口が多いのはロンバルディア州であり、経済の中心地ミラノを州都とする。都市人口比率は70%であり、先進国の中では比較的低い割合である。
