Source identity and administrative path
The source row behind Diyarbakır is GeoNames ID 316541. Its recorded administrative path is Diyarbakir Province → Türkiye, and GeoNames classifies the place as a first-order administrative seat. Diyarbakır 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 2026-04-14; 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, Diyarbakır ranks 234 by recorded population. Inside the 26 selected Türkiye entries it ranks 6; inside the 243 entries in its broad region it ranks 52. Its 1,833,684 population value is 2.31 times the 792,110 median for the country cohort and 2.03 times the 902,588 regional median. Diyarbakır falls between the leading tenth and quarter of this atlas's Türkiye population cohort. Diyarbakır's recorded value reaches at least twice the country-cohort median in this snapshot. These comparisons describe this selected dataset only; they are not current census rankings or official urban-area boundaries.
Nearest-reference pattern
Diyarbakır's three nearest other atlas coordinates are Malatya at 173.169 km with 750,491 recorded people; Erzurum at 240.029 km with 767,848 recorded people; Ar Raqqah at 243.08 km with 531,952 recorded people. The closest-to-farthest distance spread is 69.911 km. Compared with Malatya, Diyarbakır's recorded population is 2.44 times as large. Against Diyarbakır, Malatya follows Malatya → 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 first-order administrative seat class. Its recorded population is below Diyarbakır's. Against Diyarbakır, Erzurum follows Erzurum → Türkiye in the source. Its point has higher latitude and higher longitude; it belongs to the same selected Türkiye cohort, uses the shared Europe/Istanbul identifier, and carries the same first-order administrative seat class. Its recorded population is below Diyarbakır's. Against Diyarbakır, Ar Raqqah follows Raqqa → Syria in the source. Its point has lower latitude and lower longitude; it belongs to the selected Syria cohort rather than Türkiye, uses Asia/Damascus instead of Europe/Istanbul, and carries the same first-order administrative seat class. Its recorded population is below Diyarbakır's. Its nearest-neighbor distance ranks 942 of 1,206 from shortest to longest in the same snapshot. Diyarbakır'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 316541, the coordinate pair 37.9136 / 40.2172, country rank 6 of 26, and neighbor GeoNames 304922 at 173.169 km bind Diyarbakır 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
Diyarbakır's reference point is 37.9136° north and 40.2172° east. The IANA identifier Europe/Istanbul is shared by 26 city rows in this catalog, while the GeoNames class PPLA is shared by 429 rows. Diyarbakır's row carries a first-order administrative label but no second-order label. Diyarbakır's point falls in the middle-latitude coordinate band used by this atlas's row checks. Diyarbakır's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Diyarbakır, 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.
