Demographics The city was one of the largest in Europe in the High Middle Ages, with a population of 60,000 in AD 1000; 80,000 in 1200; and rising up to 110,000–180,000 in 1300. In the mid-1500s the city's population was 170,000, and by 1600 it approached 200,000. In 2021, there were 254,850 people residing in the Comune of Venice (the population figure includes 50,434 in the historic city of Venice (Centro storico), 177,621 in Terraferma (the mainland); and 26,795 on other islands in the lagoon). 47.8% of the population in 2021 were male and 52.2% were female; minors (ages 18 and younger) were 14.7% of the population compared to elderly people (ages 65 and older) who numbered 27.9%. This compared with the Italian average of 16.7% and 23.5%, respectively. The average age of Venice residents was 48.6 compared to the Italian average of 45.9. In the five years between 2016 and 2021, the population of Venice declined by 2.7%, while Italy as a whole declined by 2.2%.

Since 1991, the Church of San Giorgio dei Greci in Venice has become the see of the Greek Orthodox Archdiocese of Italy and Malta and Exarchate of Southern Europe, a Byzantine-rite diocese under the Ecumenical Patriarchate of Constantinople.
