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 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.

BackgroundInequalities in health among groups of various socio-economic status (as measured by education, occupation, and income) constitute one of the main challenges for public health. Since 2006, the Lazio Regional Outcome Evaluation Program (P.Re.Val.E.), presents a set of indicators of hospital performance based on quality standards driven by strong clinical recommendations, and measures the variation in the access to effective health care for different population groups and providers in the Lazio Region. One of the aims of the program was to compare population subgroups in order to promote equity in service provision. Since June 2013, a new management strategy has been put in place that assigned specific goals based on performance assessment to the chief executive officers of the hospitals.AimTo evaluate whether, in recent years, there has been a reduction in the differential access to effective health care, among individuals with different educational levels.MethodsWe enrolled all patients discharged from both public and private hospitals of the Lazio region between 2012 and 2015, living in Lazio region. We analysed the proportion of patients with ST-elevation myocardial infarction (STEMI) treated with percutaneous coronary intervention within 90 minutes (primary PCI), the proportion of patients with hip fracture (HF) who underwent surgery within 2 days, and the proportion of women with primary C-section. We applied multivariate logistic regression models to assess the effect of educational level on health outcomes, adjusting for demographic characteristics and comorbidities that could affect the outcomes. For each year of the study period, we compared adjusted proportions of outcomes for the highest and the lowest level of education by using percentage differences.ResultsIn the Lazio region, 44.6% of STEMI patients (N = 3,299) were treated with primary PCI, 54.4% of patients with hip fractures (N = 6,602) underwent surgery within 2 days, and 27.7% of women without a previous C-section (N = 34,718) delivered via C-section, in 2015. The corresponding proportions in 2012 were 27.8%, 31.3% and 31.5%, respectively. By comparing the adjusted proportions in patients with the highest education level (a university degree or higher) to those with the lowest level education level (None/Primary school), a decrease in the percentage difference was observed during the study period. In STEMI and delivery cohorts, the improvement of outcomes involved the least and the most educated patients, respectively, and the difference between the two educational levels was close to zero in 2015, whereas for hip patients, the improvement was more evident among the less educated patients.ConclusionsIn the Lazio region, we observed a reduction in the differential access to effective heath care by educational level, in different clinical areas. Different factors might explain these results. On top of the public disclosure of outcome data, the management strategy applied in mid-2013 might have driven the overall improvement of the health system for the considered conditions, helping to achieve a fairer access to health.

This statistic illustrates the share of population covered by broadband lines in the Italian region of Lazio in 2018, broken down by speed. According to data, the share of population covered by broadband lines with speed included in the range from 2 Mbit/s to 30 Mbit/s reached 30.37 percent.

In 2024, the capital of Italy, Rome, maintained its position as the most populous city of the Italian peninsula. Over the last decade, the number of the Eternal City’s inhabitants has been growing, from about 2.6 million residents in 2012 to over 2.8 million individuals registered in 2020. From 2021, however, its population slightly dropped, reaching 2.75 million in 2024. Lazio, the region on the Tyrrhenian SeaRome is located in the region of Lazio. This central region, which in the west borders on the Tyrrhenian Sea, is the second-largest Italian region in terms of population, after Lombardy and before Campania. Expensive life in the Italian capital Despite being one of the most affordable European capitals in terms of average monthly rent, Rome occupies the second place on the Italian podium of cities with the highest dwelling rental prices. In 2019, an average monthly rent for a single room amounted to 448 euros, whereas the average monthly price in 2020 of a double room estimated at 287 euro per person, without utilities.

As of January 2025, Italy had a population of around 59 million people. Over the past years, Italy's population decreased. An aging population and a very low birth rate are the main causes of such a contraction. Population forecasts predict that the number of residents in the country will be roughly 52.3 million by 2050. Birth rates and foreign population The birth rate in Italy declined continuously from 2002, when 9.4 babies per 1,000 inhabitants were born, to 2023, when this number dropped to 6.3. However, there was one increasing demographic trend in the country over the last years. The foreign-born population, in fact, increased from 2009 to 2023, surpassing six million people. Regional and gender distribution In Italy, female citizens were slightly more numerous than their male counterparts. The most populated region in 2025 was Lombardy, accounting for a sixth of the whole Italian population. Lazio and Campania followed, both around 5.6 million inhabitants. On the other hand, the smallest Italian region in terms of population was Aosta Valley, with only around 123,000 inhabitants.

The dataset consists of the database relating to the regional control programme of the Lazio Region for the protection of the health of the population with regard to radioactive substances present in water intended for human consumption (Legislative Decree 28/2016 – Decree of the Ministry of Health of 2 August 2017). The monitoring plan provides for sampling and analysis of total alpha and beta activity and radon in five supply areas representing approximately 50% of the regional population. Sampling is carried out by the local health authorities responsible for the area, which provide the samples to ARPA LAZIO for analysis at the Viterbo laboratory.

BackgroundThe increasing burden of chronic diseases associated with the ageing of the European population constitutes one of the main challenges for the welfare systems in developed western countries, especially through its impact on the use of hospital services and the cost of care. This study aims at evaluating the cost of hospital care for older adults living in the Lazio Region, Italy, according to their level of frailty.MethodsSince 2014 a longitudinal randomized cohort study has been carried out on a sample consisting of 1280 older adults aged over 64 years resident in the Lazio region (Italy), with their being evaluated for multidimensional frailty. Accesses to Hospital Services (acute care and Day Hospital care admissions and Emergency Room accesses) during the first year after enrolment, as well as the related costs have been recorded through a regional database. Costs have been stratified on the basis of the state of frailty.ResultsThe analysis of hospital services and costs highlights the role played by pre-frail individuals who generated 49.3% of the hospital care cumulative costs. Hospital Admission (HA) costs arising from robust and pre-frail subjects are 70% of the total HA costs. Pre-frail individuals also showed the highest average HA cost per person/year (7062.89 Euros). The main determinant of the highest HA costs was given by the number of HAs during the follow-up (multivariate linear regression, ß coefficient = 0.319; p

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.

The database returns the events of presence of the Marsican brown bear in the regional territory in the form of a grid of 2km x 2km. The occurrence events are defined on the basis of the signs of presence detected and then validated by the contacts of the Marsican Brown Bear Monitoring Regional Network according to the standards set out in the technical document ‘Criteria for planning the monitoring of the presence of the Marsican Brown Bear in peripheral areas of the distribution area in the Lazio Region’. The database also integrates the data of the presence events collected, validated and shared by the National Park of Abruzzo, Lazio and Molise (in the Lazio territory of the Park) with which the Monitoring Network of the Lazio Region operates in synergy. Presence events span the period from the 1990s to 2020. The grid does not represent the distribution of the population on the regional territory but the events of presence to date documented and validated. The presence events integrated with the cartography relating to the distribution models and environmental hygiene for the species (downloadable from the website of the Ministry of the Environment and Protection of Land and Sea at http://www.minambiente.it/page/plan-dation-the-protection-bear-marsicano-patom) represent an indispensable information layer for territorial management aimed at the conservation of the Marsican Brown Bear population. In the years 2015-2017, the Association Salviamo l'Orso collaborated with the activities of the Regional Network for the Monitoring of the Marsican Brown Bear. Since 2017, the Lazio Monitoring Network has also been working in synergy with the corresponding Abruzzo-Molise Monitoring Network through joint monitoring programmes in the Simbruini-Ernici Mountains area.

In 2019, Lombardy registered the largest number of families (4.5 millions), followed by Lazio and Campania, with 2.7 million and 2.2 million, respectively. On the contrary, the lowest number of families was recorded in Aosta Valley, where some 60 thousand families were living as of December 2019.

In fact, Lombardy is the region with the highest population, whereas Aosta Valley has the smallest amount of inhabitants nationwide.
