Hamadan

Source identity and administrative path

The source row behind Hamadan is GeoNames ID 132144. Its recorded administrative path is Hamadan Province → Iran, and GeoNames classifies the place as a first-order administrative seat.

Hamadān 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 2024-07-22; 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, Hamadan ranks 1,069 by recorded population. Inside the 15 selected Iran entries it ranks 14; inside the 243 entries in its broad region it ranks 224.

Its 528,256 population value is 0.63 times the 841,145 median for the country cohort and 0.59 times the 902,588 regional median. Hamadan sits in the lower half of this atlas's selected Iran entries.

Hamadan'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

The closest-to-farthest distance spread is 82.753 km. Compared with Arak, Hamadan's recorded population is 1.05 times as large. Against Hamadan, Arak follows Markazi → Iran in the source. Its point has lower 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 below Hamadan's. Against Hamadan, Kermanshah follows Kermanshah Province → Iran in the source. Its point has lower latitude and lower 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 Hamadan's. Against Hamadan, Qom follows Qom Province → Iran in the source.

Its point has lower 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 Hamadan's. Its nearest-neighbor distance ranks 830 of 1,206 from shortest to longest in the same snapshot. Hamadan'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 132144, the coordinate pair 34.7992 / 48.5146, country rank 14 of 15, and neighbor GeoNames 143127 at 133.83 km bind Hamadan 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

Hamadan's reference point is 34.7992° north and 48.5146° 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. Hamadan's row carries a first-order administrative label but no second-order label.

Hamadan's point falls in the middle-latitude coordinate band used by this atlas's row checks. Hamadan's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Hamadan, 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.
