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.

Naples is the Italian city with the highest population density. As of 2024, the largest south Italian city counts 7,800 inhabitants per square kilometer. Milan followed with 7,600 residents per square kilometer, whereas Rome, the largest Italian city, registered a population density of only 2,100 people, 5,700 inhabitants per square kilometer less than Naples.

In 2024, the total number of foreign residents in Italy was over five million people. In 2023, Rome and Milan were the cities with the largest presence of immigrant population, followed by Turin, Naples, and Florence.

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.

In 2025, Italy’s resident population is estimated to be almost 59 million inhabitants. About one-sixth of them lived in Lombardy, the most populous region in the country. Lazio and Campania followed, with roughly 5.7 million and 5.6 million inhabitants, respectively. These figures are mainly driven by Rome and Naples, the administrative capitals of these regions, and two of the largest metropolitan areas in the country. Which region has the oldest population? The population in Italy has become older and older over the last years. The average age in the country is equal to 46.8 years, but in some regions this figure is even higher. Liguria records an average age of 49.6 years and has one of the lowest birth rates in the country. Demographic trends for the future Liguria’s case, however, is not an outlier. Italy is already the country with the highest share of old people in Europe. At the same time, the very low number of new births means that, despite an always-increasing life expectancy, the Italian population is declining. Indeed, projections estimate that the country will have five million fewer inhabitants by 2050.

Rome, Milan, and Naples are Italy's major urban areas, respectively in the Center, North, and South of the country. In 2021, Rome had an urban area of about 4.3 million people, followed by Milan with 3.1 million and Naples with 2.2 million. In terms of population density, however, Naples is the most densely populated Italian city.

A May 2024 study analyzed the small towns in Italy with a population of under five thousand with the highest average monthly number of Google searches in 2023. Based on the analysis, two Sicilian destinations, Favignana and San Vito Lo Capo, recorded the highest figure, each with an average of 91,890 monthly Google searches in 2023. Portofino in Liguria followed in the ranking, with 91,330 monthly Google searches on average that year.

The population of Italy is getting older every year, becoming one of the oldest ones in the world. In 2025, the average age of the Italian population was 46.8 years, 3.4 years more than the average age registered in 2010. However, the age differs significantly depending on the region. According to the most recent data for 2025, the “oldest” citizens of the Italian peninsula live in the region of Liguria, with an average age 49.6 years, whereas the youngest are in Campania, 44.5 years on average. Women live longer than men The difference in the average age of the population can be observed not only on a regional basis, but also between genders. In 2021, Italian women were on average roughly three years older than men. When it comes to the life expectancy, data confirm the longevity of Italian women. In fact, females in Italy are expected to live on average about four years longer than men. The Old Continent In 2024, Europe was the continent with the highest share of population older than 65 years. Whereas the worldwide percentage of the population over 65 years was of ten percent, the percentage of elderly people in the Old Continent reached 20 percent.

In 1500, the largest city was Paris, with an estimated 225 thousand inhabitants, almost double the population of the second-largest city, Naples. As in 1330, Venice and Milan remain the third and fourth largest cities in Western Europe, however Genoa's population almost halved from 1330 until 1500, as it was struck heavily by the bubonic plague in the mid-1300s. In lists prior to this, the largest cities were generally in Spain and Italy, however, as time progressed, the largest populations could be found more often in Italy and France. The year 1500 is around the beginning of what we now consider modern history, a time that saw the birth of many European empires and inter-continental globalization.

As of January 2025, about 59 million people lived in Italy. Around 29 million individuals were males and 30 million people were females. The most populated area of the country was the north-west, where 15.9 million people lived. Furthermore, the southern regions counted 13.4 million inhabitants, representing the second most populous area of the country. Regional census The northern region of Lombardy is the most populous region of Italy. One-sixth of all the Italian population is concentrated in this area. Lazio and Campania follow with approximately 5.7 million and 5.6 million individuals, respectively. On the other hand, Aosta Valley, a northern region bordering to France and Switzerland, counted 123,000 inhabitants, representing the smallest region of Italy in terms of residents as well as area. More and more Italians are moving abroad In recent years, the number of Italians reported living abroad increased. In 2022, 5.8 million people lived outside Italy, almost three million more than in 2006. The country hosting the largest Italian population is Argentina, while other large Italian communities reside in Germany, Switzerland, and Brazil.

In 2024, the Italian region with the highest death rate was Liguria. By contrast, Trentino-South Tyrol was the area where the lowest death rate was registered in the whole country. In the period between 2010 and 2019, the annual death rate in Italy remained rather stable. In 2020, instead, the death rate increased compared to previous years. Coronavirus deaths In Italy, the first cases of coronavirus (COVID-19) were registered at the end of January 2020. Then, since the end of February, the virus started to spread among the Italian population. As of October 2021, Italy recorded 4.7 million cases of coronavirus (COVID-19) and over 130,000 deaths. Death rates in other European countries In 2019, Italy was the European country which registered the second-highest number of deaths. The state with the highest number of deceased was Germany, which is also the most populous country on the continent. On the contrary, Italy ranked only fourth, considering the size of the population.

In 2023, the Italian region which registered the highest fertility rate was Trentino-South Tyrol, where the average number of children born per female reached 1.42 infants. Over the last years, the fertility rate in Italy has constantly decreased, except for 2021 when a slight increase by 0.01 points was recorded. Fewer and fewer children born per womanThe average number of children born per female significantly varied from the middle of the twentieth century to present days. In 2017, Italian women were on average a mother of one child, whereas about seven decades earlier, females had on average at least two kids. The lowest fertility rates worldwide From the global perspective, Italy was one of the world's twenty countries with the lowest fertility rate in 2023. This figure in Taiwan reached only 1.07 children per woman, placing the country on top of the ranking.

In 2024, Trentino-South Tyrol was the region in Italy with the highest birth rate nationwide, with 7.6 births per 1,000 inhabitants. The following three positions in the ranking were occupied by Southern regions: Campania, Sicily, and Calabria. Indeed, south Italy was the macro-region with the largest birth-rate in Italy. Population change in Italy Over the past years, the natural increase in population dropped and the number of deaths exceeded the number of births. This phenomenon can be observed in every region of the country, with the number of births being lower than those of deaths in 2023. Consequently, on a national scale, the share of people aged over 65 years and over grew constantly, whereas the young population declined over the last decade. The median age is increasing as well. High lifespans for Italians Another factor that contributes to making the population older is that people are living longer than ever before. Data about life expectancy reveal that the expected lifespan at birth is rising: in 2023, it stood at 81.1 years for men and 85.2 years for women. In fact, lifespans in Italy are one of the highest worldwide, even above the European average.

In Italy, the largest part of population who live below the poverty line is located in the South. As of 2021, in three Southern regions, Apulia, Campania, and Calabria over 20 percent of the population was living below the poverty line. An Italian household with four members is considered poor when it has an availability of less than about 1.7 thousand euros a month.

In 2024, Russia had the largest population among European countries at ***** million people. The next largest countries in terms of their population size were Turkey at **** million, Germany at **** million, the United Kingdom at **** million, and France at **** million. Europe is also home to some of the world’s smallest countries, such as the microstates of Liechtenstein and San Marino, with populations of ****** and ****** respectively. Europe’s largest economies Germany was Europe’s largest economy in 2023, with a Gross Domestic Product of around *** trillion Euros, while the UK and France are the second and third largest economies, at *** trillion and *** trillion euros respectively. Prior to the mid-2000s, Europe’s fourth-largest economy, Italy, had an economy that was of a similar sized to France and the UK, before diverging growth patterns saw the UK and France become far larger economies than Italy. Moscow and Istanbul the megacities of Europe Two cities on the eastern borders of Europe were Europe’s largest in 2023. The Turkish city of Istanbul, with a population of 15.8 million, and the Russian capital, Moscow, with a population of 12.7 million. Istanbul is arguably the world’s most famous transcontinental city with territory in both Europe and Asia and has been an important center for commerce and culture for over 2,000 years. Paris was the third largest European city with a population of ** million, with London being the fourth largest at *** million.

The WHO air quality guidelines for nitrogen dioxide (NO2) and particulate matter (PM10 and PM2.5) were not followed in any of the ** metropolitan Italian cities investigated by a recent study on air pollution. The most polluted cities were Milan and Turin, where NO2 and PM2.5 concentrations were as high as over ***** and **** times the recommended WHO values, respectively.

What are the sources of air pollution?

Rome, Milan, Naples, and Turin are the largest cities in Italy. In such densely populated urban areas, fossil fuels combustion by road traffic, energy distribution, and industries are the main sources of NO2. A relevant share of PM10 is emitted by domestic heating systems, agriculture, and road vehicles, while PM2.5 is mainly of secondary origin. They are the result of chemical reactions in the atmosphere involving fossil fuels and biomass burning, nitrate and sulfate compounds, and biogenic particles.

Air pollution and health

The WHO air quality guidelines give recommendations regarding the annual mean concentrations of air pollutants that should not be exceeded to protect public health. The effects of short- and long-term exposure to elevated concentrations of NO2, PM10, and PM2.5 range from dizziness, headache, and irritation of the nose and throat to chronic pulmonary and cardiovascular diseases. PM2.5 can penetrate deeply into the respiratory system because of its small size (its diameter is smaller than *** micrometers) and is responsible for around ****** premature deaths in Italy every year.

As of January 1, 2025, Rome (Lazio) was the Italian province which registered the highest number of coronavirus (COVID-19) cases in the country. Milan (Lombardy) came second in this ranking, while Naples (Campania) and Turin (Piedmont) followed. These four areas are also the four most populated provinces in Italy. The region of Lombardy was the mostly hit by the spread of the virus, recording almost one sixth of all coronavirus cases in the country. The provinces of Milan and Brescia accounted for a large part of this figure. For a global overview, visit Statista's webpage exclusively dedicated to coronavirus, its development, and its impact.

London was by far the largest urban agglomeration in the United Kingdom in 2025, with an estimated population of *** million people, more than three times as large as Manchester, the UK’s second-biggest urban agglomeration. The agglomerations of Birmingham and Leeds / Bradford had the third and fourth-largest populations, respectively, while the biggest city in Scotland, Glasgow, was the fifth largest. Largest cities in Europe Two cities in Europe had larger urban areas than London, with Istanbul having a population of around **** million and the Russian capital Moscow having a population of over **** million.
