The population density in Italy amounted to 199.56 people in 2022. Between 1961 and 2022, the population density rose by 27.73 people, though the increase followed an uneven trajectory rather than a consistent upward trend.

Naples is the Italian city with the highest population density. As of 2025, the largest south Italian city counts 7,780 inhabitants per square kilometer. Milan followed with around 7,500 residents per square kilometer, whereas Rome, the largest Italian city, registered a population density of only 2,135 people, 5,645 inhabitants per square kilometer less than Naples.

Population density (people per sq. km of land area) in Italy was reported at 199 sq. Km in 2023, according to the World Bank collection of development indicators, compiled from officially recognized sources. Italy - Population density (people per sq. km) - actual values, historical data, forecasts and projections were sourced from the World Bank on November of 2025.

Historical dataset showing Italy population density by year from 1961 to 2022.

Italy IT: Population Density: People per Square Km data was reported at 205.859 Person/sq km in 2017. This records a decrease from the previous number of 206.118 Person/sq km for 2016. Italy IT: Population Density: People per Square Km data is updated yearly, averaging 192.689 Person/sq km from Dec 1961 (Median) to 2017, with 57 observations. The data reached an all-time high of 206.667 Person/sq km in 2014 and a record low of 171.828 Person/sq km in 1961. Italy IT: Population Density: People per Square Km data remains active status in CEIC and is reported by World Bank. The data is categorized under Global Database’s Italy – Table IT.World Bank.WDI: Population and Urbanization Statistics. Population density is midyear population divided by land area in square kilometers. Population is based on the de facto definition of population, which counts all residents regardless of legal status or citizenship--except for refugees not permanently settled in the country of asylum, who are generally considered part of the population of their country of origin. Land area is a country's total area, excluding area under inland water bodies, national claims to continental shelf, and exclusive economic zones. In most cases the definition of inland water bodies includes major rivers and lakes.; ; Food and Agriculture Organization and World Bank population estimates.; Weighted average;

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.

We reported a 13-year (2009-2022) dataset of legacy POPs (DDTtot and sumPCB14, from 2016 also isomers and congeners concentrations are reported) in the zooplankton of Lake Maggiore (≥450 µm size fraction). The data were collected seasonally in the framework of a research program, funded by CIPAIS (Commissione Italiana per la Protezione delle Acque Italo-Svizzere), aimed at monitoring the presence of pollutants in the lake biota, particularly in the zooplankton size fraction directly linked to fish consumption. The dataset provides also the Standing Stock Density (SSD) and Standing Stock Biomass (SSB) of pelagic zooplankton organisms belonging to the size fraction ≥450 µm.

Sites of National Interest (SIN) are large portions of the national territory, of particular environmental value in the various environmental matrices (including any surface water bodies and their sediments), identified by law, for reclamation purposes, on the basis of characteristics (of contamination and others) that entail a high health and ecological risk due to population density or the extension of the site itself, as well as a significant socio-economic impact and a risk for assets of historical and cultural interest. The layer contains the perimeter at sea of coastal Sites of National Interest in Italy.
