Karaj

Source identity and administrative path

The source row behind Karaj is GeoNames ID 128747. Its recorded administrative path is Alborz Province → Iran, and GeoNames classifies the place as a first-order administrative seat.

Karaj 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 2021-08-20; 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, Karaj ranks 338 by recorded population. Inside the 15 selected Iran entries it ranks 4; inside the 243 entries in its broad region it ranks 69.

Its 1,448,075 population value is 1.72 times the 841,145 median for the country cohort and 1.60 times the 902,588 regional median. Karaj falls between the leading tenth and quarter of this atlas's Iran population cohort.

Karaj's recorded value is above the country-cohort median but remains below twice that benchmark. These comparisons describe this selected dataset only; they are not current census rankings or official urban-area boundaries.

Nearest-reference pattern

Karaj's three nearest other atlas coordinates are Tehran at 41.73 km with 7,153,309 recorded people; Qom at 133.018 km with 900,000 recorded people; Rasht at 203.623 km with 594,590 recorded people. The closest-to-farthest distance spread is 161.893 km. Compared with Tehran, Karaj's recorded population is 0.20 times as large. Against Karaj, Tehran follows Tehran → 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 capital of a political entity rather than first-order administrative seat.

Its recorded population is above Karaj's. Against Karaj, Qom follows Qom 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 below Karaj's. Against Karaj, Rasht follows Gilan Province → Iran in the source.

Its point has higher 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 below Karaj's. Its nearest-neighbor distance ranks 373 of 1,206 from shortest to longest in the same snapshot. Karaj's nearest-coordinate gap sits in the second quarter 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 128747, the coordinate pair 35.8327 / 50.9916, country rank 4 of 15, and neighbor GeoNames 112931 at 41.73 km bind Karaj 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

Karaj's reference point is 35.8327° north and 50.9916° 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. Karaj's row carries a first-order administrative label but no second-order label.

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