Changchun

Source identity and administrative path

The source row behind Changchun is GeoNames ID 2038180. Its recorded administrative path is Changchun Shi → Jilin → China, and GeoNames classifies the place as a first-order administrative seat.

Changchun 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 2026-04-13; 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, Changchun ranks 64 by recorded population. Inside the 296 selected China entries it ranks 22; inside the 632 entries in its broad region it ranks 40.

Its 4,714,996 population value is 4.05 times the 1,165,375 median for the country cohort and 4.68 times the 1,008,426 regional median. Changchun falls inside the leading tenth of this atlas's China population cohort.

Changchun'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.

Its recorded population is above Changchun's. Its nearest-neighbor distance ranks 695 of 1,206 from shortest to longest in the same snapshot. Changchun'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 2038180, the coordinate pair 43.8800 / 125.3228, country rank 22 of 296, and neighbor GeoNames 2036502 at 99.322 km bind Changchun 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

Changchun's reference point is 43.8800° north and 125.3228° east. The IANA identifier Asia/Shanghai is shared by 291 city rows in this catalog, while the GeoNames class PPLA is shared by 429 rows. Changchun's row carries both second- and first-order administrative labels.

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