01What the data says — and does not say
This page separates the checked GeoNames row for İzmir—2,938,292, Europe/Istanbul, and source coordinates—from live travel claims. Those fields identify and compare the record; they do not prove current transport, accessibility, census totals, or a City Atlas Club visit.
Wikidata's localized description: city in İzmir Province, Turkey.
02This city's dataset fingerprint
The source row behind İzmir is GeoNames ID 311046. Its recorded administrative path is Izmir Province → Türkiye, and GeoNames classifies the place as a first-order administrative seat. İzmir 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 2026-06-21; that date belongs to the source record, not to every transport or visitor detail in the real destination.
Within the fixed 1,206-record atlas, İzmir ranks 122 by recorded population. Inside the 26 selected Türkiye entries it ranks 4; inside the 243 entries in its broad region it ranks 25. Its 2,938,292 population value is 3.71 times the 792,110 median for the country cohort and 3.26 times the 902,588 regional median. İzmir falls between the leading tenth and quarter of this atlas's Türkiye population cohort. İzmir'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.

Against İzmir, Karabağlar district follows Karabaglar → Izmir Province → Türkiye in the source.

Its recorded population is below İzmir's. Against İzmir, Nilüfer follows Niluefer → Bursa Province → 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 second-order administrative seat rather than first-order administrative seat.

Its recorded population is above İzmir's. Its nearest-neighbor distance ranks 28 of 1,206 from shortest to longest in the same snapshot. İzmir'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 311046, the coordinate pair 38.4127 / 27.1384, country rank 4 of 26, and neighbor GeoNames 7701384 at 3.462 km bind İzmir to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
İzmir's reference point is 38.4127° north and 27.1384° 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. İzmir's row carries a first-order administrative label but no second-order label. İzmir's point falls in the middle-latitude coordinate band used by this atlas's row checks. İzmir's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for İzmir, 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.
