Source identity and administrative path
The source row behind Algiers is GeoNames ID 2507480. Its recorded administrative path is Algiers → Algeria, and GeoNames classifies the place as a capital of a political entity. Algiers occurs once as a primary city label in this atlas sample; the numeric ID remains the durable source key if names change. The city row itself was updated 2024-08-05; that date belongs to the source record, not to every transport or visitor detail in the real destination.
Population position inside fixed cohorts
Within the fixed 1,206-record atlas, Algiers ranks 163 by recorded population. Inside the 2 selected Algeria entries it ranks 1; inside the 243 entries in its broad region it ranks 32. Its 2,364,230 population value is 1.49 times the 1,583,780 median for the country cohort and 2.62 times the 902,588 regional median. Algiers is rank 1 among the 2 selected Algeria entries, so a percentage band would overstate this small cohort. Algiers's recorded value is above the country-cohort median but remains below twice that benchmark. These comparisons describe this selected dataset only; they are not current census rankings or official urban-area boundaries.
Nearest-reference pattern
Algiers's three nearest other atlas coordinates are Oran at 353.202 km with 803,329 recorded people; City of Valencia (Spain) at 430.014 km with 824,340 recorded people; Oujda at 505.369 km with 539,711 recorded people. The closest-to-farthest distance spread is 152.167 km. Compared with Oran, Algiers's recorded population is 2.94 times as large. Against Algiers, Oran follows Oran → Algeria in the source. Its point has lower latitude and lower longitude; it belongs to the same selected Algeria cohort, uses the shared Africa/Algiers identifier, and carries first-order administrative seat rather than capital of a political entity. Its recorded population is below Algiers's. Against Algiers, City of Valencia (Spain) follows Provincia de Valencia → Valencia → Spain in the source. Its point has higher latitude and lower longitude; it belongs to the selected Spain cohort rather than Algeria, uses Europe/Madrid instead of Africa/Algiers, and carries first-order administrative seat rather than capital of a political entity. Its recorded population is below Algiers's. Against Algiers, Oujda follows Oujda-Angad → Oriental → Morocco in the source. Its point has lower latitude and lower longitude; it belongs to the selected Morocco cohort rather than Algeria, uses Africa/Casablanca instead of Africa/Algiers, and carries first-order administrative seat rather than capital of a political entity. Its recorded population is below Algiers's. Its nearest-neighbor distance ranks 1,144 of 1,206 from shortest to longest in the same snapshot. Algiers's nearest-coordinate gap belongs to the wider half of atlas distances. This pattern can reveal whether other catalog references are geographically close, but it cannot establish whether a border crossing is possible or practical, or whether rail, road, fare, or journey-time connections exist. Read as one record signature, GeoNames 2507480, the coordinate pair 36.7323 / 3.0875, country rank 1 of 2, and neighbor GeoNames 2485926 at 353.202 km bind Algiers to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
Coordinate, time-zone and class cohorts
Algiers's reference point is 36.7323° north and 3.0875° east. The IANA identifier Africa/Algiers is shared by 2 city rows in this catalog, while the GeoNames class PPLC is shared by 129 rows. Algiers's row carries a first-order administrative label but no second-order label. Algiers's point falls in the middle-latitude coordinate band used by this atlas's row checks. Algiers's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Algiers, so the profile preserves that missing value instead of guessing terrain. Together these fields form a reproducible identity check for this page, not a claim about walkability, climate or accessibility.
