Source identity and administrative path
The source row behind Üsküdar is GeoNames ID 738329. Its recorded administrative path is UEskuedar → Istanbul → Türkiye, and GeoNames classifies the place as a populated place. Üsküdar 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 2024-08-02; 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, Üsküdar ranks 1,080 by recorded population. Inside the 26 selected Türkiye entries it ranks 23; inside the 243 entries in its broad region it ranks 226. Its 524,452 population value is 0.66 times the 792,110 median for the country cohort and 0.58 times the 902,588 regional median. Üsküdar sits in the lower half of this atlas's selected Türkiye entries. Üsküdar's recorded value is materially below the country-cohort median used here. These comparisons describe this selected dataset only; they are not current census rankings or official urban-area boundaries.
Nearest-reference pattern
Üsküdar's three nearest other atlas coordinates are Istanbul at 5.46 km with 15,701,602 recorded people; Ümraniye at 9.347 km with 573,265 recorded people; Esenler at 11.759 km with 520,235 recorded people. The closest-to-farthest distance spread is 6.299 km. Compared with Istanbul, Üsküdar's recorded population is 0.03 times as large. Against Üsküdar, Istanbul follows Istanbul → Türkiye in the source. Its point has lower latitude and lower longitude; it belongs to the same selected Türkiye cohort, uses the shared Europe/Istanbul identifier, and carries first-order administrative seat rather than populated place. Its recorded population is above Üsküdar's. Against Üsküdar, Ümraniye follows UEmraniye → Istanbul → Türkiye in the source. Its point has lower latitude and higher longitude; it belongs to the same selected Türkiye cohort, uses the shared Europe/Istanbul identifier, and carries the same populated place class. Its recorded population is above Üsküdar's. Against Üsküdar, Esenler follows Esenler → Istanbul → Türkiye in the source. Its point has higher latitude and lower longitude; it belongs to the same selected Türkiye cohort, uses the shared Europe/Istanbul identifier, and carries the same populated place class. Its recorded population is below Üsküdar's. Its nearest-neighbor distance ranks 63 of 1,206 from shortest to longest in the same snapshot. Üsküdar's nearest-coordinate gap belongs to the tightest tenth of the atlas. 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 738329, the coordinate pair 41.0227 / 29.0137, country rank 23 of 26, and neighbor GeoNames 745044 at 5.46 km bind Üsküdar 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
Üsküdar's reference point is 41.0227° north and 29.0137° east. The IANA identifier Europe/Istanbul is shared by 26 city rows in this catalog, while the GeoNames class PPL is shared by 243 rows. Üsküdar's row carries both second- and first-order administrative labels. Üsküdar's point falls in the middle-latitude coordinate band used by this atlas's row checks. Üsküdar's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Üsküdar, 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.
