Chart and table of population level and growth rate for the Bologna, Italy metro area from 1950 to 2025.

Residents in the municipality of Bologna increased from 2010 to 2022 by two percent. In 2011, the city recorded the lowest number of citizens of the decade, slightly above 370,000 inhabitants. However, from 2012 a constant growth started until 2019, when the peak was reached with 395,000 people. Since then, a decreasing trend occurred which stabilized the resident population around 390,000 individuals, making Bologna the seventh-biggest city in Italy.

The mean age in Bologna between 2010 and 2022 presented a decreasing trend. In fact, from 47.3 years old at the beginning of the decade, the average age dropped to 46.8 years old in 2022, 0.5 points less than in 2010. Overall, Bologna remains above the Italian mean age, corresponding to 46.4 years old for 2022, but, among others, one reason for the slightly diminishing pattern could be found in the city's ability to constantly attract young students, the University of Bologna being one of the biggest and most prestigious in the country.

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.

In 2023, the biggest communities of foreign nationals in Italy were in Milan, Bologna, Florence, Turin, Rome, and Genoa, where more than ten percent of the inhabitants were not of Italian origin. These cities are mostly located in the north of the country. On the contrary, in the southern municipalities of Bari, Catania, and Palermo the incidence of the immigrant population is minimal, well below five percent. Italian demographics In 2024, beyond five million foreign residents lived in Italy, compared to the total population of 59 million inhabitants. Projections assert that in the upcoming years, the number of Italian citizens will progressively decrease, mostly given to the aging population and low birth rates. In fact, it has been predicted that the median age could reach 53.6 years by 2050, whereas the country experienced a constant decline in the number of births. In 2010, almost 550,000 babies came into life, but ten years later only 400,000 births were recorded. The divide between north and south From the distribution of immigrant residents, there is an evident separation between the northern Italian regions and the southern part of the country, making those territories less attractive for foreigners in terms of work opportunities. Analysis on the index of the gross domestic product (GDP) per capita in 2005, in 2015 and 2025 reveal that the total wealth produced by the southern region represents only half of the one recorded in the north. Moreover, in 2023 the unemployment rate in northern regions was around four percent, whereas in the south it reached 14 percent.

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.

Neighborhood houses. The Municipality of Bologna has launched the project ‘Case di Quartiere per un welfare di comunità’ (Neighbourhood Houses for Community Welfare), which aims to give continuity to the experience of the Social Centres, rooted in the civic and administrative tradition of our community, and to support their renewal together. The dataset contains the location data on the map with the indication of the address and relative name of the neighborhood where they are located.The Neighborhood Houses are:-collaborative and accessible spaces, able to facilitate the meeting between citizens, and in which to experiment a collaborative way also in terms of forms of management, available to multiple realities;-open and flexible spaces, social garrisons and "bridge" between generations, cultures and needs, respond to the needs of encounter and socialization, to counter loneliness and activate proximity networks;-point of reference for the elderly population in terms of services and opportunities to combat relational poverty, promoting sociality, recreational and cultural activities, health prevention, and integrating them into an intergenerational perspective.

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.

Introduction Health administrative databases are widely used for the estimation of the prevalence of Parkinson’s Disease (PD). Few in general, and none used in Italy, have been validated by testing their diagnostic accuracy. The primary objective was to validate two algorithms for the identification of persons with PD using clinical diagnosis as the reference standard on an Italian sample of people with PD. The second objective was to estimate 10-year trends in PD prevalence in the Bologna Local Health Trust from 2010 to 2019. Methods Two algorithms (index tests) applied to health administrative databases (hospital discharge, drug prescriptions, exemptions for medical costs) were validated against clinical diagnosis of PD by an expert neurologist (reference standard) in a cohort of consecutive outpatients. Sensitivity and specificity with relative 95% confidence intervals (CI) were calculated. The prevalence of PD in a specific year was estimated as the ratio between the number of subjects fulfilling any criteria of the algorithm with better diagnostic accuracy and the total population in the same year (x 1,000), stratified by age, sex and district of residence. Results The two algorithms showed high accuracy for identifying patients with PD: one with greater sensitivity 94.2% (CI 88.4 – 97.6) and the other with greater specificity 98.1% (CI 97.7 – 98.5). For the estimation of prevalence, we chose the most specific algorithm with the fewest total number of misclassified cases. We identified 3,798 people with PD as of December 31, 2019 corresponding to a prevalence of 4.3 per 1,000 inhabitants (CI 4.2 – 4.4). Prevalence was higher in males (4.7, CI 4.5 – 5.0) than females (3.8, CI 3.7 – 4.0) and increased with age. The crude prevalence over time was slightly elevated as it followed a progressive ageing of the population. When stratifying the prevalence for age groups we did not observe a trend except in the 45-64 year category where we observed an increasing trend over time. Conclusion Algorithms based on administrative data are accurate when detecting people with PD in the Italian public health system. In a large northern Italian population, increased prevalence of about 10% was observed in the decade 2010-2019 and is explained by increased life expectancy. These data may be useful in planning the allocation of health care resources for people with PD.

Milan, Bologna, Genoa, Florence, and Turin recorded a population increase between 2022 and 2023. In fact, all the other largest municipalities registered a decrease, most prominently in the south and on the islands. However, Naples is the third-largest Italian municipality, after Rome and Milan.

In the academic year 2023/2023, 112,000 students were enrolled at La Sapienza University of Rome, the largest Italian university. Pegaso online University followed with 99,600 enrollments. Around 84,000 students attended classes in Bologna, the oldest university in the world and the best in the country. Finally, the University of Turin collected 77,000 students. In total, 1.9 million undergraduates were enrolled at Italian universities. Ancient, public, and digital higher education Among the 20 largest Italian universities, 16 of them are public institutes. The four private universities are the Catholic University of Milan and three online universities. Among them, Pegaso University was founded in 2006 and counts 95,000 students. Many of the world's oldest higher-learning institutions are located in Italy. The University of Bologna is the oldest university, continuously operating since 1088. In 1222, scholars from Bologna founded the University of Padua. Two years later, in 1224, the University of Naples Federico II was established, the oldest public and secular institution globally. In the 14th century were constituted the universities of Perugia, Siena, Pisa, and Pavia. Popular courses of study Back in the Middle Ages, the University of Bologna offered mainly subjects of liberal arts, law, and theology. However, these seem to rank lower among the most common degrees nowadays. Almost 270,000 students in Italy enrolled in medicine programs, the most popular field of study. Moreover, economics was the second most chosen degree program.

The 4th century BC marks the main entrance of Celtic populations in northern Italy. Their arrival has been suggested based on the presence of Celtic customs in Etruscan mortuary contexts, yet up to now few bioarchaeological data have been examined to support or reject the arrival of these newcomers. Here we use strontium isotopes, non-metric dental traits and funerary patterns to unravel the biocultural structure of the necropolis of Monterenzio Vecchio (Bologna, Italy). Subsamples of our total sample of 38 individuals were analyzed based on different criteria characterizing the following analyses: 1) strontium isotope analysis to investigate migratory patterns and provenance; 2) non-metric dental traits to establish biological relationships between Monterenzio Vecchio, 13 Italian Iron age necropolises and three continental and non-continental Celtic necropolises; 3) grave goods which were statistically explored to detect possible patterns of cultural variability. The strontium isotopes results indicate the presence of local and non-local individuals, with some revealing patterns of mobility. The dental morphology reveals an affinity between Monterenzio Vecchio and Iron Age Italian samples. However, when the Monterenzio Vecchio sample is separated by isotopic results into locals and non-locals, the latter share affinity with the sample of non-continental Celts from Yorkshire (UK). Moreover, systematic analyses demonstrate that ethnic background does not retain measurable impact on the distribution of funerary elements. Our results confirm the migration of Celtic populations in Monterenzio as archaeologically hypothesized on the basis of the grave goods, followed by a high degree of cultural admixture between exogenous and endogenous traits. This contribution shows that combining different methods offers a more comprehensive perspective for the exploration of biocultural processes in past and present populations.
