Source identity and administrative path
The source row behind Orūmīyeh is GeoNames ID 121801. Its recorded administrative path is West Azerbaijan → Iran, and GeoNames classifies the place as a first-order administrative seat. Orūmīyeh 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 2024-07-17; 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, Orūmīyeh ranks 964 by recorded population. Inside the 15 selected Iran entries it ranks 12; inside the 243 entries in its broad region it ranks 196. Its 577,307 population value is 0.69 times the 841,145 median for the country cohort and 0.64 times the 902,588 regional median. Orūmīyeh sits in the lower half of this atlas's selected Iran entries. Orūmīyeh'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
Orūmīyeh's three nearest other atlas coordinates are Tabriz at 121.835 km with 1,424,641 recorded people; Erbil at 178.669 km with 1,612,700 recorded people; Van at 181.53 km with 525,016 recorded people. The closest-to-farthest distance spread is 59.695 km. Compared with Tabriz, Orūmīyeh's recorded population is 0.41 times as large. Against Orūmīyeh, Tabriz follows East Azerbaijan → Iran in the source. Its point has higher latitude and higher longitude; it belongs to the same selected Iran cohort, uses the shared Asia/Tehran identifier, and carries the same first-order administrative seat class. Its recorded population is above Orūmīyeh's. Against Orūmīyeh, Erbil follows Arbil → Erbil → Iraq in the source. Its point has lower latitude and lower longitude; it belongs to the selected Iraq cohort rather than Iran, uses Asia/Baghdad instead of Asia/Tehran, and carries the same first-order administrative seat class. Its recorded population is above Orūmīyeh's. Against Orūmīyeh, Van follows Van → Türkiye in the source. Its point has higher latitude and lower longitude; it belongs to the selected Türkiye cohort rather than Iran, uses Europe/Istanbul instead of Asia/Tehran, and carries the same first-order administrative seat class. Its recorded population is below Orūmīyeh's. Its nearest-neighbor distance ranks 779 of 1,206 from shortest to longest in the same snapshot. Orūmīyeh'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 121801, the coordinate pair 37.5527 / 45.0761, country rank 12 of 15, and neighbor GeoNames 113646 at 121.835 km bind Orūmīyeh 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
Orūmīyeh's reference point is 37.5527° north and 45.0761° east. The IANA identifier Asia/Tehran is shared by 15 city rows in this catalog, while the GeoNames class PPLA is shared by 429 rows. Orūmīyeh's row carries a first-order administrative label but no second-order label. Orūmīyeh's point falls in the middle-latitude coordinate band used by this atlas's row checks. Orūmīyeh's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Orūmīyeh, 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.
