Algeria DZ: Population Density: People per Square Km data was reported at 19.094 Person/sq km in 2022. This records an increase from the previous number of 18.793 Person/sq km for 2021. Algeria DZ: Population Density: People per Square Km data is updated yearly, averaging 11.046 Person/sq km from Dec 1961 (Median) to 2022, with 62 observations. The data reached an all-time high of 19.094 Person/sq km in 2022 and a record low of 4.883 Person/sq km in 1961. Algeria DZ: 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 Algeria – Table DZ.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 2023, Algiers was the city with the largest population in Algeria, with nearly 1.98 million inhabitants. The cities of Boumerdès and Oran followed with around 786,000 and 646,000 people, respectively. Most of the population is concentrated in the cities With an area of over 2.48 million square kilometers, Algeria is the largest country in Africa. Since the territory is predominantly desert, most of the population lives in the coastal areas by the Mediterranean Sea. This explains why the population density remains relatively low at around 18.6 inhabitants per square kilometer, although it is constantly increasing. In addition, due to internal migration from rural areas, as well as population growth, Algerian cities are becoming more populous and the urbanization rate in the country is increasing annually. In 2022, around 75 percent of the population lived in urban areas. Algeria’s population continues to grow Algeria ranks among the most populous countries in Africa, counting nearly 46 million inhabitants as of 2023. The total population has been increasing constantly and registered a growth rate of 1.63 percent in 2022. In the coming years, the population is forecast to reach around 49.6 million by 2029. The relatively high fertility rate, together with the rising life expectancy and declining mortality, would drive population growth in the country.

🇩🇿 Algeria — Population & Density by Wilaya (WorldPop 2020)

This dataset provides population and population density estimates for all Algerian wilayas, derived from:

• WorldPop 2020 Unconstrained Population Density (1 km resolution, CC-BY-4.0)
• GADM v4.1 Administrative Boundaries (Level 1: Wilaya)

The WorldPop population raster (XYZ format) was converted into point features and spatially aggregated inside GADM wilaya polygons using GeoPandas. For each wilaya, we computed:

Variables

• NAME_1 — Wilaya name
• total_population — sum of all WorldPop 1 km cell values inside the wilaya
• area_km2 — polygon area in square kilometers (computed using UTM projection)
• pop_density_per_km2 — total_population / area_km2

Files included

• wilaya_population_density.csv — clean table of population and density
• wilaya_population_density.geojson — full geospatial dataset with polygon geometries

Use cases

• Choropleth mapping
• Urban planning & demographic analysis
• Socio-economic research
• GIS or GeoPandas workflows

Roads can constrain movements of individuals and consequently gene flow across landscape. There is a consensus among experts that some species show road surface and width avoidance behavior. However, little attention has been paid on how spatial behavior can be translated into mortality risk and population genetic structure. With this study we examine the strength of the barrier effects of different roads types (4-lane highway, 2-lane paved road and unpaved road) on three rodent species with varying life-history traits: water vole Arvicola sapidus, pine vole Microtus duodecimcostatus and algerian mouse Mus spretus. More specifically, we address 1) the influence of traffic on individual movements, 2) the effect of road type (width/pavement) on crossing rates, 3) the annual risk of mortality and 4) the genetic structure of populations on both sides of the different roads. A total of 79 voles were caught in the vicinity of roads and 6481 locations were recorded through radio tracking. We used generalized linear mixed models to evaluate the effect of traffic on individual movements, compared observed crossing rates with simulations without roads, and used the information of number of crossings per individual and the probability of being killed while crossing a road to estimate the annual mortality risk. We also obtained 200 tissue samples for pine vole and Algerian mouse and estimate the genetic differentiation (FST) among groups of samples on both sides of roads. As expected, paved roads function as artificial territorial boundaries for the three species. Traffic intensity had only negative influence on water vole movements. Crossing rates decrease as the road width increase and paved roads have a negative effect on individual’s crossings, except for pine vole that had the highest crossing rate, and the 2-lane highway show a neutral effect. The likelihood of being killed during a crossing event at high traffic highway segments for pine vole and Algerian mouse at 4-lan highways were 0.22 and 0.05, respectively. Unexpectedly, pine vole populations show genetic structure at 4-lane highways while Algerian mouse populations did not show significant genetic structure for all type of roads. Our study shows that daily movement patterns of small mammals towards roads cannot be translated on dispersal and gene flow. Further information is needed to understand the implications of mortality risk in the viability of pine vole population occurring in the vicinity of heavy traffic roads. We recommend that only complementary studies of spatial behavior, population density and genetics may explain the mechanisms underlying the barrier effect of roads on wildlife.
