Rome is the most populous city in Italy. With 2.75 million inhabitants, the capital of the country put ahead Milan and Naples. Compared to the number of citizens in 2012, the resident population of Rome increased by over 140,000 individuals. Regional data Rome is located in the center of Italy in the Lazio region. Lazio is the second-largest region in terms of population size after Lombardy. In 2024, the region counts roughly 5.7 million inhabitants, whereas Lombardy has over ten million individuals. The third-largest region is Campania, with 5.6 million people. Naples, the major center of Campania, has around 910,000 inhabitants at the beginning of 2024. Nevertheless, this city was, back in the 19th century, one of the largest cities in Western Europe. Tourism in Rome The Eternal City is also the main tourist destination in Italy and was the eighth most-visited city in Europe. The largest groups of international visitors in Rome came from the United States of America, Japan, and the United Kingdom. Every year, more and more tourists also enjoy the best-known tourist attractions in Rome, like the Colosseum, the Roman Forum, and the Palatine Hill, which together recorded almost ten million visitors in 2022.

This statistic shows the ten largest cities in Italy in 2025. In 2025, around 2.75 million people lived in Rome, making it the largest city in Italy. Population of Italy Italy has high population figures and a high population density in comparison to other European countries. A vast majority of Italians lives in urban areas and in the metropolises (as can be seen in this statistic), while other areas, such as the island Sardinia, are rather sparsely inhabited. After an increase a few years ago, Italy’s fertility rate, i.e. the average amount of children born to a woman of childbearing age, is now on a slow decline; however, it is still high enough to offset any significant effect the decrease might have on the country’s number of inhabitants. The median age of Italy’s population has been increasing rapidly over the past 50 years – which mirrors a lower mortality rate – and Italy is now among the countries with the highest life expectancy worldwide, only surpassed by two Asian countries, namely Japan and Hong Kong. Currently, the average life expectancy at birth in Italy is at about 83 years. Most of Italy’s population is of Roman Catholic faith. The country actually boasts one of the largest numbers of Catholics worldwide; other such countries include Brazil, Mexico and the United States. The central government of the Roman Catholic Church, the Holy See, is located in Vatican City in the heart of Italy’s capital and ruled by the Bishop of Rome, the Pope. Officially, Vatican City does not belong to Italy, but is a sovereign state with its own legislation and jurisdiction. It has about 600 inhabitants, who are almost exclusively members of the clergy or government officials.

Throughout the early modern period, the largest city in Italy was Naples. The middle ages saw many metropolitan areas along the Mediterranean grow to become the largest in Europe, as they developed into meeting ports for merchants travelling between the three continents. Italy, throughout this time, was not a unified country, but rather a collection of smaller states that had many cultural similarities, and political control of these cities regularly shifted over the given period. Across this time, the population of each city generally grew between each century, but a series of plague outbreaks in the 1600s devastated the populations of Italy's metropolitan areas, which can be observed here. Naples At the beginning of the 1500s, the Kingdom of Naples was taken under the control of the Spanish crown, where its capital grew to become the largest city in the newly-expanding Spanish Empire. Prosperity then grew in the 16th and 17th centuries, before the city's international importance declined in the 18th century. There is also a noticeable dip in Naples' population size between 1600 and 1700, due to an outbreak of plague in 1656 that almost halved the population. Today, Naples is just the third largest city in Italy, behind Rome and Milan. Rome Over 2,000 years ago, Rome became the first city in the world to have a population of more than one million people, and in 2021, it was Italy's largest city with a population of 2.8 million; however it did go through a period of great decline in the middle ages. After the Fall of the Western Roman Empire in 476CE, Rome's population dropped rapidly, below 100,000 inhabitants in 500CE. 1,000 years later, Rome was an important city in Europe as it was the seat of the Catholic Church, and it had a powerful banking sector, but its population was just 55,000 people as it did not have the same appeal for merchants or migrants held by the other port cities. A series of reforms by the Papacy in the late-1500s then saw significant improvements to infrastructure, housing, and sanitation, and living standards rose greatly. Over the following centuries, the Papacy consolidated its power in the center of the Italian peninsula, which brought stability to the region, and the city of Rome became a cultural center. Across this period, Rome's population grew almost three times larger, which was the highest level of growth of these cities.

Rome is the largest Italian metropolitan area. As of 2024, the urban area of the capital city has a population of around 4.23 million people. Milan and Naples follow with 3.25 million and 2.97 million people, respectively. In terms of inhabitants per square kilometer, Naples, located in the south, has the highest population density. Rome, Milan, and Naples are also Italy's largest cities.

It is estimated that the largest cities in Western Europe in 1330 were Paris and Granada. At this time, Paris was the seat of power in northern France, while Granada had become the largest multicultural city in southern Spain, controlled by the Muslim, Nasrid Kingdom during Spain's Reconquista period. The next three largest cities were Venice, Genoa and Milan, all in northern Italy, renowned as important trading cities during the middle ages.

The Italian real estate market, valued at approximately €XX million in 2025, exhibits robust growth potential, driven by a compound annual growth rate (CAGR) exceeding 5% through 2033. This expansion is fueled by several key factors. Increased tourism and a growing luxury market, particularly in renowned cities like Rome, Florence, and Venice, significantly contribute to demand. Furthermore, a rising influx of foreign investors seeking high-quality properties and the increasing popularity of Italian lifestyle contribute to the market's dynamism. The market is segmented into villas and landed houses, apartments and condominiums, further differentiated geographically across major Italian cities and other regions. While the luxury segment commands significant attention, the broader market reflects diverse needs and price points, catering to both domestic and international buyers. Potential constraints to growth include economic uncertainties and fluctuating government regulations influencing property investment. However, the overall outlook remains positive, projecting sustained growth driven by the enduring appeal of Italian real estate and increasing global interest. The major players in the Italian real estate market, including Christie's International Real Estate, Sotheby's International Realty, and numerous local agencies, are well-positioned to capitalize on this expansion. The regional distribution of investment reflects global interest, with North America, Europe, and the Asia-Pacific region showing significant participation. Future growth is anticipated to be influenced by broader economic conditions, shifts in investor sentiment, and infrastructural developments. Continuous monitoring of these factors will be crucial for accurate market forecasting. Maintaining a competitive landscape, along with innovative marketing strategies and property management solutions, will likely determine success within this dynamic sector. The overall market shows considerable resilience and potential for substantial expansion over the next decade.
